Methodology
The purpose of this study report is to provide recommendations and guidance to American Lime Technology on
which ASTM material tests may best fit the projected use and formulation of Tradical Hemcrete.

Tradical Hemcrete is a unique product that replaces several other building materials in a wall assembly: gypsum
board, vapor retarder, siding, insulation, sound baffles, etc. As such, research was undertaken as part of this study to
ascertain the building materials Hemcrete replaces and how those materials are traditionally tested. ModCell Hemp
was not evaluated as part of this report.

As part of this study the project team:
• Reviewed all previous completed testing and product data
• Utilized the IBC (International Building Code) to ascertain how code official may view Hemcrete
• Met with the client to discuss the future goals for product use
• Established the materials Hemcrete replaces in a building wall assembly
• Identified similar “traditional” and “innovation” building materials that have previously undertaken similar testing
• Identified appropriate ASTM tests
• Identified appropriate test agencies
• Identified the impact of regional issues (i.e. humidity, seismic, wind, etc...)

Fi n d i n g s M a t r i x
The information provided in the Matrix depicts the types of construction and ASTM test. The intent of this matrix is to
provide recommendations on what test likely suite specific types of construction. The use of this matrix should assist
in targeting ASTM tests that most suite your goals for Tradical Hemcrete in the United States.

Tests denoted as “required” for code compliance on the matrix are essential to receive code approval for product use.
Tests denoted in the matrix as “recommended” are not specifically required by code but are strongly encouraged to
collect hard product data and inform code officials. Tests denoted as “not critical” are more driven towards gathering
product data for marketing purposes and general information but not essential to any code official requirements.
Tests denoted as ”not applicable” do not apply to the type of construction. Please note that “recommended” tests
also speak to issues addressing individual states which may have regionally specific issues such as hurricanes. The
information provided in no way speaks to standards in other countries.

Ty p e s o f C o n s t r u c t i o n
Pages 8 and 9 provide information on types of construction including definitions and typical building types. This
information is critical in determining the types of buildings targeted for the Hemcrete market. Use this information
to supplement the decision making process provided in the Matrix for determining which ASTM test are the most
valuable to your end goal market needs at this time.

A S T M Te s t s D e f i n e d
The information provided in the section “ASTM Tests Defined” is meant to provide American Lime Technologies
with a synopsis of information pertinent to determining which tests may be the most appropriate and how they
are implemented. In their complete form, each ASTM section fully defines and instructs testing agencies as to how
testing should actually be carried out. This in depth information is lengthy and not necessary for your purposes. Gaps
in numeric sequences are not errors but are omissions of data more pertinent to testing agencies.

NOTE: Each test is considered proprietary. Once testing is complete and Hemcrete passes, compliance with the ASTM standard
is only achieved through exact duplication of how the material was formulated/installed at the time of testing. Therefore,
each sample/mock-up supplied to the labs should be an exact replica of how the product will be installed/specified in the
field. Compiled march 2009 5

ASTM: E 84 Surface Burning Characteristics of Building Materials
0.0 Preface
This test is the standard to establish the relative behavior of a finish material when exposed to open flame.

1.0 Scope
1.1 This fire-test-response standard for the comparative surface burning behavior of building materials is
applicable to exposed surfaces such as walls and ceilings. This test is conducted with the specimen in the
ceiling position with the surface to be evaluated exposed face down to the ignition source. The material,
product, or assembly shall be capable of being mounted in the test position during the test. Thus, the
specimen shall either be self-supporting by its own structural quality, held in place by added supports along
the test surface, or secured from the back side.
1.2 The purpose of this test method is to determine the relative burning behavior of the material by observing
the flame spread along the specimen. Flame spread and smoke developed index are reported. However,
there is not necessarily a relationship between these two measurements.
1.3 The use of supporting materials on the underside of the test specimen has the ability to lower the flame
spread index from those which might be obtained if the specimen could be tested without such support.
These test results do not necessarily relate to indices obtained by testing materials without such support.
1.4 Testing of materials that melt, drip, or delaminate to such a degree that the continuity of the flame front
is destroyed, results in a low flame spread indices (measurement) that do not relate directly to indices by
testing materials that remain in place.

4.0 Significance and use
4.1 This test method is intended to provide only comparative measurements of surface flame spread and smoke
density measurements with that of select grade red oak and reinforced cement board surfaces under the
specific fire exposure conditions described herein.
4.2 This test method exposes a nominal 24 ft (7.32-m) long by 20 in. (508 mm) wide specimen to a controlled
air flow and flaming fire exposure adjusted to spread the flame along the entire length of the select grade
red oak specimen in 5 1/2 min.
4.3 This test method does not provide the following:
4.3.1 Measurement of heat transmission through the tested surface.
4.3.2 The effect of aggravated flame spread behavior of an assembly resulting from the proximity of combustible
walls and ceilings.
4.3.3 Classifying or defining a material as noncombustible, by means of a flame spread index by itself.

6.0 Test Specimens
6.2 The specimen shall be provided in one of two ways: (1) a continuous, unbroken length; (2) sections that will
be joined or butted end-to-end.
6.3 The size of the test specimen shall be:
Width: between 20 and 24 in. (508 and 610mm)
Length: 24 ft. + 12 in. - 6 in.
Thickness: maximum 4 in. (101 mm)

ASTM: E 119 Fire Tests of Building Construction and Materials
0.0 Preface
This test is the standard to establish the fire resistance of a building assembly (a system of components or
materials).

1.0 Scope
1.1 The test methods described in this fire-test-response standard are applicable to assemblies of masonry
units and to composite assemblies of structural materials for buildings, including bearing and other walls
and partitions, columns, girders, beams, slabs, and composite slab and beam assemblies for floors and roofs.
They are also applicable to other assemblies and structural units that constitute permanent integral parts of
a finished building.
1.3 This standard is used to measure and describe the response of materials, products, or assemblies to heat and
flame under controlled conditions, but does not by itself incorporate all factors required for fire hazard or
fire risk assessment of the materials, products or assemblies under actual fire conditions.
1.4 These test methods prescribe a standard fire exposure for comparing the test results of building construction
assemblies. The results of these tests are but one factor in assessing predicted fire performance of building
construction and assemblies. Application of these test results to predict the performance of actual building
construction requires the evaluation of test conditions.

4.1 This test method is intended to evaluate the duration for which the types of assemblies notes in 1.1 contain
fire, retain their structural integrity, or exhibit both properties dependent upon the type of assembly involved
during a predetermined test exposure.
4.2 The test exposes a specimen to a standard fire controlled to achieve specified temperatures throughout
a specified time period. When required, the fire exposure is followed by the application of a specified
standard fire hose stream. The test provides a relative measure of the fire-test-response of comparable
assemblies under these fire exposure conditions. The exposure is not representative of all fire conditions
because conditions vary with changes in the amount, nature and distribution of fire loading, ventilation,
compartment size and configuration, and heat sink characteristics of the compartment. Variation from the
test conditions or specimen construction, such as size, materials, method of assembly, also affects the fire-
test response. For these reasons, evaluation of the variation is required for application to construction in the
field.
4.3 This test standards provides for the following:
4.3.1 For walls, partitions, and floor or roof assemblies:
4.3.1.1 Measurement of the transmission of heat.
4.3.1.2 Measurement of the transmission of hot gases through the assembly, sufficient to ignite cotton waste.
4.3.1.3 For load bearing elements, measurement of the load carrying ability of the test specimen during the test
exposure.

9.0 Test Specimen
9.1 The test specimen shall be truly representative of the construction for which classification is desired, as
to materials, workmanship, and details such as dimensions of parts, and shall be built under conditions



representative of those obtaining as practically applied in building construction and operation. The physical
properties of the materials and ingredients used in the test specimen shall be determined and recorded.
9.2 The size and dimensions of the test specimen specified herein shall apply for rating constructions of
dimensions within the range employed in buildings. When the conditions of use limit the construction to
smaller dimensions, the dimensions of the specimen shall be reduced proportionately for a test qualifying
them for such restricted use.

TEST OF BEARING WALLS AND PARTITIONS
14.0 Size of Specimen
14.1 The area exposed to fire shall be not less than 100 ft2 (9m2), with neither dimension less than 9 ft. (2.7 m).
The test specimen shall not be restrained on its vertical edges.

TEST OF NONBEARING WALLS AND PARTITIONS
17.0 Size of Specimen
17.1 The area exposed to fire shall be not less than 100 ft2 (9m2), with neither dimension less than 9 ft. (2.7 m).
Restrain the test specimen on all four edges.

ASTM: E 136 Behavior of Materials in a Vertical Tube Furnace
0.0 Preface
This test is the standard to establish if a material is combustible or non-combustible.

1.0 Scope
1.1 This fire-test-response test method covers the determination under specified laboratory conditions of
combustion characteristics of building materials. It is not intended to apply to laminated or coated surfaces.
1.4 This standard is used to measure and describe the response of materials, products, or assemblies to heat and
flame under controlled conditions, but does not by itself incorporate all factors required for fire hazard or
fire risk assessment of the materials, products or assemblies under actual fire conditions.

4.1 While actual building fire exposure conditions are not duplicated, this test method will assist in indicating
those materials which do not act to aid combustion or add appreciable heat to an ambient fire.
4.2 Materials passing the test are permitted limited flaming and other indications of combustion.

6.0 Test Specimen
6.1 All test specimens shall be 38 by 38 by 51 + 2.5 mm (1.5 by 1.5 by 2.0 + 0.1 in.). The specimens shall be dried
at 60 + 3oC (140 + 5oF) for not less than 24 hour but no more than 48 hours. Specimens shall not be placed
in a desiccator to cool at least 1 hour before testing.
6.2 Not less than four identical specimens shall be tested.

8.0 Report
8.1 Report the material as passing the test if at least three of the four specimens tested meet the individual
specimen criteria detailed in 8.2 or 8.3. The three specimens do not need to meet the same condition.
8.2 When the weight loss of the specimens is 50% or less:
8.2.1 The recorded temperatures of the surface and interior thermocouples do not at any time during the test rise
more than 30oC (54oF) above the stabilized temperature measured at T2 prior to the test.
8.2.2 There is no flaming from the specimen after the first 30 seconds.
8.3 When the weight loss of the specimen exceeds 50%:
8.3.1 The recorded temperature of the surface and interior thermocouples do not at any time during the test rise
above the stabilized temperature measured at T2 prior to the test.
8.3.2 There is no flaming from the specimen at any time during the test.

ASTM: E 736 Cohesion/Adhesion of Sprayed Fire-Resistive Materials
Applied to Structural Members
0.0 Preface
This test establishes how well an applied fire-resistive material adheres to structural steel.

1.0 Scope
1.1 This test method covers a procedure for measuring the cohesion/adhesion or bond strength (tensile)
perpendicular to the surface of sprayed fire-resistive material (SFRM) applied to rigid backing. These fire-
resistive materials include sprayed fibrous and cementitious materials. The test method is applicable to both
laboratory and field procedures as indicated in Section 7.

4.1 The intent of this test method is to determine a property of SFRM that may be used to provide an indication
of its in-place serviceability. Satisfactory performance of SFRM applied to structural members and assemblies
depends upon its ability to withstand the various influences that may occur during construction and during
the life of the structure, as well as upon its satisfactory performance under fire conditions.

7.0 Test Specimen
Note: The specimen can either be laboratory or field tested.
7.1 Laboratory Tests:
7.1.1 The SFRM shall be applied at a thickness of 12 mm to 25 mm (1/2 in. to 1 in.) to the 300 by 300 mm (12 by
12 in.) galvanized steel sheet.
7.1.2 Condition the specimen at room temperature (20+ 10oC (68 + 18oF)). After 72 h, samples may be forced
dried in a drying oven at 43 + 6oC (110 + 10oF), and a relative humidity not greater than 60% until successive
weight readings, taken at 8 h intervals, differ by less than 1 percent.
7.1.3 Testing may be performed after it has been determined that all samples have reached constant weight as
defined in 7.1.2.
7.2 Field Tests:
7.2.1 The test specimen shall be the in-place SFRM as applied to any field condition surface. Where a 300 mm
(12 by 12 in.) area is not available, such as on beams and fluted deck, use the width of the beam or the
width of a flute by 300 mm (12 in.) length. The area shall be at least 100 by 300 mm (4 by 12 in.). See 5.2 for
exceptions.
7.2.2 Condition the specimen at atmospheric conditions or in accordance with the manufacturer’s
recommendations for a period sufficient to be considered dry.
7.2.3 Mechanical ventilation may be employed on the manufacturers’ recommendation to expedite drying.

8.0 Procedure
8.1 Apply adhesive sufficient to fill the metal or plastic cap, and immediately place the cap against the surface
of the SFRM.
8.2 Support the cap at the surface until the adhesive has adequately cured. Wipe away any excess adhesive
around the cap before it cures, or carefully cut it away after it cures.



8.3.1 Restrain the specimen with the SFRM facing up to prevent movement and flexing during testing.
8.3.2 Engage the scale with the hook and exert an increasing force at a minimum uniform or incremental rate of
approximately 5 kg (11 lb)/min perpendicular to the surface.
8.3.3 Force shall be applied until failure occurs, a predetermined value is reached, or until the capacity of the scale
is reached.
8.4 Field Tests:
8.4.1 Perform tests as described in 8.3.2-8.3.4.
8.4.2 A nondestructive field test may be performed by replacing the scale with a fixed weight that must be
supported for 1 min.

10.0 Report
10.1 Report the following information:
10.1.1 Force, newtons (pounds force),
10.1.2 Cohesion/adhesive force (bond strength), pascals (pounds per
10.1.3 Description of the type of failure.
10.1.4 Approximate area of material involved in the failure, if it extends beyond the perimeter of the cap.
10.1.5 Thickness of the SFRM.
10.1.6 Density of the SFRM.

ASTM: E 759 Effect of Deflection on Sprayed Fire-Resistive Materials
0.0 Preface
This test establishes how well an applied fire-resistive material bonds to steel decks while under bending
stress.

1.0 Scope
1.1 This test method covers a procedure for determining the effect of deflection on sprayed fire-resistive
material (SFRM) applied to steel deck. Thee materials include sprayed fibrous and cementitious materials
applied directly in contact with the structural members. The test method is applicable only to laboratory
procedures.

3.0 Summary of Test Method
3.1 In this test method a cellular steel deck panel sprayed with fire-resistive material is subjected to bending by
a vertical center load while supported horizontally at its ends.

4.1 The intent of this test method is to determine properties of direct-applied SFRM that may be used to provide
an indication of serviceability. Satisfactory performance of fire-resistive material applied to structural
members and assemblies depends upon its ability while in place to withstand the various influences that
may occur during the life of the structure, as well as upon its satisfactory performance under fire tests.
4.2 This test method measures the behavior of SFRM when subjected to deflection and evaluates such
phenomena as spalling and delamination under bending stress. It is an indication of the ability of SFRM to
remain in place and resist removal during anticipates service conditions.

7.0 Test Specimen
7.1 Apply the SFRM to the underside of the steel deck at a minimum 19 mm (3/4 in.) thickness. Do not apply
the SFRM to the area 330 mm (13 in.) from each end of the specimen, in order to permit the steel deck to
bear directly on the supports.
7.2 Condition the prepared specimen for a period of not less than one week at ambient temperatures and
humidity conditions (but not less than 4.4oC (40oF)) until cured.
7.3 Condition the specimen for a period sufficient to be considered dry in accordance with the manufacturers’
recommendations.

8.0 Procedure
8.1 Place the specimen on the test supports with the SFRM as the lower surface.
8.2 To measure the deflection of the specimen, record the initial reading of the dial micrometer prior to the
application of the load and record the deformation of the load applied.
8.3 Apply a vertical center load to the upper face of the specimen by means of a bearing block to develop a
deflection of 1/120 of the clear span, that is, 25 mm (1.0 in.).



9.0 Report
9.1.1 Condition of the test specimen when it has deflected the required 1/120 the clear span,
9.1.2 Any spalling or delamination, and
9.1.3 Thickness of the SFRM in millimeters (or inches) and the density in kilograms per cubic metre (or pounds per
cubic foot).

ASTM: E 760 Effect of Impact on Bonding of Sprayed Fire-Resistive
Materials Applied to Structural Members
0.0 Preface
This test establishes how well an applied fire-resistive material bonds to steel decks while under bending
stress.

1.0 Scope
1.1 This test method covers a procedure for determining the effect of impact loading on the bonding of sprayed
fire-resistive material (SFRM) applied to the underside of steel floor deck. These materials include sprayed
fibrous and cementitious materials applied directly in contact with the structural members. The test method
is applicable only to laboratory procedures.

of its in-place serviceability. Satisfactory performance of SFRM applied to structural members and assemblies
depends upon its ability to withstand the various influences that may occur during construction and during
the life of the structure, as well as upon its satisfactory performance under fire conditions.
4.2 The test method measures the behavior of SFRM when the floor construction to which it is applied is
subjected to shock loading and evaluates adhesion and resistance to spalling, cracking, and delamination.

ASTM: E 761 Compressive Strength of Sprayed Fire-Resistive Materials
0.0 Preface
This test establishes the compressive strength of an applied fire-resistive material after being applied to
structural steel.

1.0 Scope
1.1 This test method covers a procedure for measuring the compressive strength of sprayed fire-resistive material
(SFRM) applied to a rigid substrate. These fire-resistive materials include sprayed fibrous and cementitious
materials applied directly in contact with the structural members. The test method is applicable only to
laboratory procedures.

3.1 The compressive strength of SFRM applied to steel sheet is determined by applying a crushing load normal
to the surface of the specimen. This test method measures the stress at 10% deformation or at failure,
whichever is smaller.

4.1 The intent of this test method is to determine properties of direct-applied SFRM that may be used to provide
an indication of its serviceability. Satisfactory performance of fire-resistive material applied to structural
members and assemblies depends upon its ability to withstand the various influences that may occur
during the life of the structure, as well as upon its satisfactory performance under fire tests.
4.2 The test method measures the compressive strength of SFRM and is a measure of the resistance to
deformation under a compressive load. It is an indication of the ability of SFRM to remain in place and resist
removal during anticipated service conditions.

6.0 Materials
6.1 This test method requires the application of SFRM in accordance with manufacturer’s published instructions.
The apparatus, materials, and procedures used to apply the SFRM fro this test shall be representative of
application in the field.

18oF)) and at a relative humidity not greater than 60%. After 72 h, the specimen may be forced dried in a
dying oven at 43 + 6oC (110 + 10oF), and at a relative humidity not greater than 60% until reachig constant
weight.
7.4 Testing may be performed after it has been determined that the specimen has reached constant weight.
7.5 Where necessary, even the surface of the specimen at two areas 150 mm (6 in.) square at opposite ends of
the specimen with an appropriate capping material such as polyurethane, epoxy, polyester, or other similar
materials. The top plane of the capping material shall not exceed the thickest point of the test area of a test
specimen with an irregular surface by more than 1.3 mm (0.05 in.).
7.6 Make two compression tests at opposite ends of the test specimen. Make one density test on the
specimen.

ASTM: C 1363 Thermal Performance
0.0 Preface
This test establishes the insulative value of a material more commonly known as “R-value”.

1.0 Scope
1.1 This test method covers the laboratory measurement of heat transfer through a specimen under controlled
air temperature, air velocity, and thermal radiation conditions established in a metering chamber on one
side and in a climate chamber on the other side.
1.2 This test method generally is used for large homogeneous or nonhomogeneous specimens. This test
method may be used for any building structure or composite assemblies of building elements for which it
is possible to build a representative specimen of a size that is appropriate for the testing apparatus.
1.3 This test method is intended for use at conditions typical of normal building applications. The usual
consideration is to duplicate naturally occurring outside conditions that in temperate zones may range
from approximately -48 to 85oC and normal inside residential temperatures of approximately 21oC. Building
materials used to construct the specimens are generally pre-conditioned to typical laboratory conditions of
23oC and 50% relative humidity prior to assembly.
1.4 The test method permits operation under natural or forced convective conditions at the specimen surface.
The direction of air flow motion may be either perpendicular or parallel to the surface.
1.8 This test method does not permit intentional mass transfer of air or moisture through the specimen during
measurements of energy transfer. Air infiltration or moisture migration can significantly alter net heat
transfer.

5.1 There is a need for accurate data on heat transfer through insulations and through insulated structures.
The data are needed to judge compliance with specifications and regulations as well as design guidance,
for research evaluations of the effects of changes in materials or construction, and verification of, or use in,
simulation models/energy models.
5.2 For the results to be representative of a building construction, only representative full-scale sections should
be tested. The specimens should be duplicate framing geometry, material composition and installation
practice, and orientation of construction.

7.0 Test Specimens
7.1 The test specimens shall be representative of typical product (field) applications.
7.1.1 Size - The specimen shall be sized for the apparatus. Normally, the outside dimensions of the specimen
must match the inside dimensions of the specimen frame. If smaller elements must be tested, a surround
panel may be used to fill out the required size.

11.0 Calculation
11.2 Average Temperature Determination:
11.2.1 When operated under steady-state conditions with temperatures held constant during a test, the results
maybe expressed as either thermal resistance, R, thermal conductance, C, overall thermal resistance Ru, or
thermal transmittance, U. This allows two procedures which are to be used in determining the average


A S T M Te s t s D e f i n e d : T H E R M A L P E R F O R M A N C E

surface temperatures used in the calculations. The choice between the two procedures depends upon the
uniformity of the specimen and thus upon whether sufficiently uniform surface temperature exist that they
can be measured by temperature sensors and a representative average obtained.
The two procedures are :
11.2.1.1 For uniform and nearly uniform specimens, the average surface temperatures may be determined from area
weighted measurements from the temperature sensors installed as directed in 6.10. The thermal resistance,
R, is then calculated using the measured heat transfer and the difference in the average temperatures of the
two surfaces.
11.2.2 For very nonuniform specimens, meaningful average surface temperatures will not exist. In this case the
thermal resistance, R, is calculated by subtracting surface resistance fro the two surfaces from the measured
overall thermal resistance, Ru. These surface resistances shall be determined from tests conducted
under similar conditions, but using a uniform test specimen of approximately the same overall thermal
resistance.

12.0 Report
12.1.10 Net heat transfer through the specimens, steady-state average rate or the average amount per cycle or
other stated time interval for dynamic tests. Include values for metering box loss, flanking loss, and other
losses included in the net energy calculation.
12.1.11 Any thermal transmission properties calculated in 11.3 (“Calculation of Thermal Properties”), and their
estimated error.

Segmental Retaining Wall units and Related Concrete
units
0.0 Preface
This test establishes the behavior of a material to freeze/thaw cycles.

1.0 Scope
1.1 This test method covers the resistance to freezing and thawing of dry-cast segmental retaining wall (SRW)
units (see Specification C 1372) and related concrete units. Units are tested in a test solution that is either
water or 3% saline solution depending on the intended use of the units in actual service. (Note 1: Related
concrete units include units such as hollow and solid concrete masonry units, concrete brick, and concrete
roof pavers.)
1.2 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses
are mathematical conversions to SI units that are provided for information only and are not considered
standard.

4.1 The procedure described in this test method is intended to determine the effects of freezing and thawing
on SRW and related units in the presence of water or saline solution.
4.2 This procedure is not intended to provide a quantitative measure to determine an expected length of
service for a specific type of concrete unit.

6.0 Sampling
6.1 Selection of Test Specimens - Select while units representative of the lot from which they have been selected.
The units shall be free from visible cracks or structural defects.
6.2 Number of Specimens - Select five SRW units for freeze-thaw tests.

9.0 Calculation and Report
9.1 Determine and report the cumulative weight loss of each residue collection interval expressed in terms of g
(lb) and as a percent of the calcualted initial weight of the specimen determined in accrodance with 8.3.5.
Where the coupon thickness is less than 1.25 in. (32mm), the percentage and cumulative weight loss shall
be multiplied by a value equal to the actual thickness in inches (mm) divided by 1.25 in. (32mm). Report
these values for each specimen as well as the average of the specimens tested.
(8.3.5 - At the completion of the freezing-and thawing testing, dry each specimen at 212 to 239 oF (100 to
155oC) for 24+ 1h. Weigh to the nearest 1 g (0.002lb) the final oven-dried specimen and record the final
weight.

ASTM: D 3273 Resistance to Growth of Mold on the Surface of Interior
Coatings in an Environmental Chamber
0.0 Preface
This test measures the resistance to mold growth on or within the material.

1.0 Scope
1.1 This test method describes a small environmental chamber and the conditions of operation to evaluate
reproducibility in a 4 week period the relative resistance of paint films to surface mold fungi, mildew growth
in a severe interior environment.
1.2 This test method can be used to evaluate the comparative resistance of interior coating to accelerated
mildew growth. Performance at a certain rating does not imply and specific period of time for a fungal free
coating. However, a better rated coating nearly always performs better in actual end use.

3.1 An accelerated test for determining the resistance of interior coatings to mold growth is useful in estimating
the performance of coatings designed for use in interior environments that promote mold growth and in
evaluating compounds that may inhibit such growth and the aggregate levels for their use.

5.0 Reagents and Materials
5.3.2 Gypsum Board Panels, 12.7 mm (1/2 in.) thick, 75 by 100 mm (3 by 4 in.). Note: These panels (after an initial
mold growth stage) are coated with the surface coating to be tested i.e. lime wash.

8.0 Report
8.1 Report the results at the end of the 4 week exposure giving the mean and range of the three panels. The
result from any panel that differs by more than 2 rating units from either of the others can be considered
manifestly faulty and discarded and the mean of the remaining two panels reported. If all panels in a set
differ by more than 2 units in their ratings, discard all results and repeat the test.

ASTM: E 1886 Performance of Exterior Windows, Curtain Walls, Doors,
and Storm Shutters Impacted by Missles(s) and Exposed
to Cyclic Pressure Differentials
TKWA Note: Given that this test is typically structured around the wind speed maps for a particular region, we
suggest selecting a region that typifies hurricane level event wind loads for maximum results.

0.0 Preface
This test establishes the materials resistance to flying debis. The test is primarily used to evaluate windows.
however, testing hemcrete would establish the strength and durability to aborant weather conditions. It is
not out of the ordinary to test building materials in this manner.

1.0 Scope
1.1 This test method determines the performance of exterior windows, curtain walls, doors, and storm
shutters impacted by missile(s) and subsequently subjected to cyclic static pressure differentials. A missile
propulsion device, an air pressure system, and a test chamber are used to model some conditions which
may be representative of windborne debris and pressures in a windstorm environment. This test method is
applicable to the design of entire fenestration or shutter assemblies and their installation. The performance
determined by this test method relates to the ability of elements of the building envelope to remain
unbreached during a windstorm (i.e. hurricane or tornado).

4.1 This test method consists of mounting the test specimen, impacting the test specimen with a missile(s), and
then applying cyclic static pressure differentials across the test specimen in accordance with a specified test
loading program, observing and measuring the condition of the test specimen, and reporting the results.

5.1 Structural design of exterior windows, curtains walls, doors, and storm shutters is typically based on positive
and negative design pressure(s). Design pressures based on wind speeds with a mean recurrence interval
(usually 25-100 years) that relates to desired levels of structural reliability and are appropriate for the type
and importance of the building. The adequacy of the structural design is substantiated by other Test
Methods such as E 330 and E 1233 which discuss proof loads as added factors of safety. However, these test
methods do not account for other factors such as impact from windborne debris followed by fluctuating
pressures associated with a severe windstorm environment. As demonstrated by windstorm damage
investigations, windborne debris is present in hurricanes and has caused significant amount of damage
to building envelopes. The actual in-service performance of fenestration assemblies and storm shutters in
areas prone to severe windstorms is dependent on many factors. Windstorm damage investigations have
shown that the effects of windborne debris, followed by the effects of repeated or cyclic wind loading, were
a major factor in building damage.



5.1.1 Many factors affect the actual loading on building surfaces during a severe windstorm, including varying
wind direction, duration of the wind event, height above ground, building shape, terrain, surrounding
structures, and other factors. The resistance of fenestration or shutter assemblies to wind loading after
impact depends upon the product design, installation, load magnitude, duration, and repetition.
5.1.2 Windows, doors, and curtain walls are building envelope components often subject to damage in
windstorms. The damage caused by windborne debris during windstorms goes beyond failure of building
envelope components such as windows, doors, and curtain walls. Breaching of the envelope exposes a
building’s content to the damaging effects of continued wind and rain. A potentially more serious result
is internal pressurization. When the windward wall of a building is breached, the internal pressure in the
building increases, resulting in increased outward acting pressure on the other walls and roof. The intyernal
pressure coefficient (see ANSI/ASCE 7), which is one of several design parameters, can increase by a factor
as high as four. This can increase the net outward acting pressure by a factor as high as two.
5.2 In this test method, a test specimen is first subjected to specified missile impact(s) followed by the application
of a specified number of cycles of positive and negative static pressure differential. The assembly must satisfy
the pass/fail criteria established by the specifying authority, which may allow damage such as deformation,
deflection, or glass breakage.
5.3 The windborne debris generated during a severe windstorm varies greatly, depending upon windspeed,
height above the ground, terrain, surrounding structures, and other sources of debris. Typical debris in
hurricanes consists of missiles including, but not limited to, roof gravel, roof tiles, signage, portions of
damaged structures, framing lumber, roofing materials, and sheet metal... The missiles and their associated
velocity ranges used in this test method are selected to reasonably represent typical debris produced by
windstorms.
5.4 To determine design wind loads, average wind speeds are translated into air pressure differences.
Superimposed on the average winds are gusts whose aggregation, for short periods of time (ranging from
fractions of seconds to a few seconds) may move at considerably higher speeds than the averaged winds.
Wind pressures related to building design, wind intensity versus duration, frequency of occurrence, and
other factors are considered.
5.4.1 Wind speeds are typically selected for particular geographic locations and probabilities of occurrence from
wind speed maps such as those prepared by the National Weather Service, from appropriate wind load
documents such as ANSI/ANCE 7 or from building codes enforced in a particular geographic region.
5.4.2 Equivalent static pressure differences are calculated using the selected wind speeds.
5.5 Cyclic pressure effects on fenestration assemblies after impact by windborne debris are significant. It is
appropriate to test the strength of the assembly for a time duration representative of sustained winds and
gusts in a windstorm. Gust wind loads are of relatively short duration. Other test methods such as E 330 and
E 1233, do not model gust loadings. They are not to be specified for the purpose of testing the adequacy of
the assembly to remain unbreached in a windstorm environment following impact by windborne debris.



8.0 Test Specimen
8.1 The test specimen shall consist of the entire fenestration or shutter assembly and contain all devices used to
resist wind and windborne debris. Test specimens for large fenestrations and curtain wall assemblies shall
be one panel unless otherwise specified.

ASTM: E 90 Airborne Sound Transmission Loss of Building Partition
and Elements (acoustic properties)
0.0 Preface
This test establishes the materials sound absorbing behavior.

1.0 Scope
1.1 This test method covers the laboratory measurement of airborne sound transmission loss of building
partitions such as walls of all kinds, operable partitions, floor-ceiling assemblies, doors, windows, roofs,
panels, and other space-dividing elements.

5.1 Sound transmission loss refers to the response of specimens exposed to a diffuse incident sound field, and
this is the test condition approached by this laboratory test method. The test results are therefore most
directly relevant to the performance of similar specimens exposed to similar sound fields. They provide,
however, a useful general measure of performance for the variety of sound fields to which a partition or
element may typically be exposed.

7.0 Test Specimens
7.1 Size and Mounting - Any test specimen that is to typify a wall or floor shall be large enough to include all the
essential construction elements in their nominal size, and in a proportion typical of actual use. The minimum
dimension (excluding thickness) shall be 2.4 m (7’-10 1/2”), except that specimens of doors, office screens,
and other smaller building elements shall be their customary size. Preformed panel structures should
include at least two complete modules (panels plus edge mounting elements), although single panels can
be tested. In all cases the test specimen shall be installed in a manner similar to actual construction, with a
careful simulation of normal constraint and sealing conditions at the perimeter and at joints within the field
of the specimen.
7.2 Aging of Specimens - Test specimens that incorporate materials for which there is a curing process (for
example adhesives, plasters, concrete, mortar, damping compound) shall age for a sufficient interval before
testing. Manufacturers may supply information about curing times for their products.

13.0 Report
13.1.1 A description of the test specimen.
13.1.6 Sound transmission losses rounded to the nearest decibel for the frequency bands required and any other
measured.
13.1.6.1 Identify data affected by flanking transmission or background noise.
13.1.8 The temperature and humidity in the rooms during the measurement.
13.1.9 The volumes of the test rooms.
13.1.11 Single Number Ratings:
13.1.11.1 Sound Transmission Class - If single number rating are given, the sound transmission class described in
Classification E 413 shall be included.

13.1.11.2 Outdoor-Indoor Transmission Class - Where the test specimen may be used as part of a facade of a building,
the Outdoor-Indoor transmission class should be included. This single number rating is intended to rate
the effectiveness of building facade elements at reducing transportation noise intrusion.

LEED and hemcrete: Evaluation of Potential LEED Point Opportunities
The following are LEED credits that Hemcrete could potentially contribute towards on a LEED project. A project
team filing LEED documentation would need MSDS sheets confirming this information, or documentation on
Manufacturer letterhead stating the claims. (Please note that this document is based on requirements for LEED for
New Construction v2.2. This is the current standard, which is being updated to v3.0 (a.k.a. LEED 2009) scheduled for
release in Spring 2009.)

Based upon our review of Hemcrete, it is potentially eligible for the following 9 LEED points. These points are subject
to review and documentation on a project-by-project basis and assume Hemcrete components will eventually be
produced in the Unites States.

LEED Compliance Evaluation

MRc4 Recycled Content: (3 points possible)
Summary
1. Use building materials with recycled content.
2. Recycled content value of a material assembly shall be determined by weight. The recycled fraction of the
assembly is then multiplied by the cost of the assembly to determine the recycled value.
3. Recycled content shall be defined in accordance with the International Organization for Standardization Document,
ISO 14021-Environmental labels and declarations-Self-declared environmental claims (Type II environmental
labeling)
• Pre-consumer material is defined as material diverted from the waste stream during the manufacturing
process. Excluded is reutilization of materials such as rework, regrind or scrap generated in the process
and capable of being reclaimed within the same process that generated it.
• Post-consumer material is defined as waste material generated by households or by commercial, industrial,
and institutional facilities in their role as end-users of the product, which can no longer be used for its
intended purpose.
4. Post-Consumer recycled content is calculated using 100% of material value.
5. Pre-Consumer recycled content is calculated using 50% of the material value.
• Recycled Content Value ($) = (% Post-consumer Recycled Content x Material Cost) + 0.5 x (% Pre-consumer
Recycled Content x Material Cost)
6. For assembly (products that are composed of multiple materials) recycled content values, consider the percents
by weight of the post- and pre-consumer recycled content in the assembly.
7. In the case of supplementary cementitious materials (SCMs) used in concrete that are recycled from other
operations, it is allowable to calculate the recycled content value based on the mass of the cementitious materials
only rather then on the entire concrete mix. (See Example 1: Sample Supplementary Cementitious materials
Calculation)

LEED Documentation Requirements from Manufacturer:
• Description of the material
• List Manufacturer
• Identify the percentage of post-consumer and/or pre-consumer recycled content by weight

of the project site for a minimum of 10% or 20% (based on cost) of the total materials value.
2. IF only a fraction of the product or material is extracted/harvested/recovered and manufactured locally, then only
that percentage (by weight) shall contribute to the regional value.
3. Reused and Salvaged materials may also contribute. Location they were salvaged is the point of extraction, and
the location of the salvaged goods vendor is the point of manufacture.
4. For material with more then one point of manufacture or extraction:
• IF all within the 500-mile radius list the single item with the greatest distance.
• IF a portion of the material is from beyond the 500-mile radius, list only the portion and associated cost
satisfying the credit requirement

Innovation and Design Credits
Innovation and Design (ID) credits are credit opportunities that are not associated with any single rating system.
These are credits that were developed by individual project teams that submitted their innovative methods. If
their credit ideas are approved by USGBC, future projects can follow the credit methodology to achieve a point for
following the same methods. A list of accepted ID credits are available on the USGBC website. (www.usgbc.org)

ID-SS/EQ: Integrated Pest Management: (1 point possible)
Summary
1. Implement an Integrated Pest Management (IPM) program that demonstrates a comprehensive approach that
utilizes environmentally control methods.
2. NOTE: Hemcrete won’t directly relate to this credit since it is primarily planning and method related. However,
Hemcrete could help eliminate a need for toxic control methods.

• Documentation stating that the Hemcrete product is naturally pest resistant and would be a positive asset to an
IPM program.
