1.1
1. GENERAL REQUIREMENTS
a. Detailed requirements for Type and Production testing are given in Sections 2.
and 3. respectively.
1.1 Site of Tests
a. Each equipment is to be tested at the works of the equipment manufacturer or
elsewhere as approved.
1.2 Test Facilities
a. Machinery supports and holding down arrangements are to simulate as closely
as possible those for onboard installation, unless otherwise approved.
b. Lubrication of equipment during tests is to be similar to the installed onboard
arrangements.
c. The test rig is to simulate the associated system so that all functions are subject
to operational conditions unless otherwise approved.
d. Ancillary equipment, eg starter and cut-out switches, is to be the same as that
used in service when available. Where not available slave equipment may be
used.
e. Services to be provided by the contractor or test establishment are to include
electricity, water, drainage and air supplies.
f. Consumable materials can be obtained from Naval Stores and may include fuel,
oil and refrigerant.
g. When fuel has been supplied from other than MOD sources, a sample is to be
sent to the Superintendent, Naval Petroleum Chemistry and Technology
Division, Royal Aircraft Establishment, Fairmile, Cobham, Surrey KT11 1B5
for determination of the calorific value.
h. Instrumentation is to be fitted to record each parameter including quantity of
flow, temperatures and pressures, and these are to be measured at each point
where there is significant variation. Additionally the speed (and torque where
appropriate) are to be measured and recorded from any output shaft.
i. The instrumentation is to be of sufficient accuracy to enable significant
variations to be noted. This is to include a high degree of sensitivity and a rapid
response to fluctuations. A sensitivity of 1% of the maximum scale value
throughout the anticipated range is the minimum acceptable recording level.
j. All instruments are to be calibrated prior to the type test and selected
instruments calibrated after the test. Instruments used for Production Testing
are to be calibrated periodically in accordance with AQAP−6.
k. Safety precautions are to be in accordance with current requirements.
Note: In general with test facilities, it is also advisable that an equipment is
tested in conjunction with the specific item(s) with which it will be
associated on the ship whenever the performance of the associated units
is likely to affect the primary equipment. For example, experience has
shown that it is essential that prototype tests on auxiliary boilers are
carried out using the distilling plant appropriate to the ship fit.

Issue 3 (Reformatted)
2.4
c. Before equipment is type tested a record is to be made by direct measurement
of the dimensions of wearing parts and clearances, unless these dimensions are
available from the manufacturing records of the equipment. See ‘Examinations
for Wear’, Clause 2.3n.
d. All protective devices are to be tested to establish satisfactory operation. Tests
to establish actuation speeds, pressures and temperatures are to be repeated not
less than 5 times and each result recorded. Where appropriate, rapid variations
of speed or pressure are to be imposed to establish the time response of the
system.
(1) Relief valve: test to establish the pressures at which the relief valve lifts,
is fully open and reseats, also establish the flow when fully open and
confirm that the valve is tight at design working pressure before lifting
and after reseating, and establish accumulation pressure.
(2) Overspeed emergency trip of rotating machinery:
(a) demonstrate that trip operates within the following limits:
Diesel engines Approved trip speed +0, −2½%
Other units both
electrical and mechanical
Approved trip speed +2½%, −2½%
(b) demonstrate hand operation and resetting of trip.
(3) Lubricating oil failure emergency trip: demonstrate actuation of the trip
at the pre-set pressure and record pressure.
(4) High temperature emergency trip: demonstrate actuation of the trip at
the pre-set temperature and record temperature.
Note: Turbo-generators and main turbines as fitted in submarines have a
vacuum trip arrangement.
e. Control equipment and governor operational tests: each control device is to be
tested to establish satisfactory operation over the full range of control. It is to
be demonstrated that the control device can cope with the most severe single or
cyclic signal variation that is specified.
f. Overspeed tests:
(1) Diesel and Petrol Engines
On completion of the performance tests, the overspeed trip is to be
rendered inoperative and the engine run for a period of 15 minutes at a
speed which is either 20% in excess of its nominal full speed or is 5% of
nominal speed greater than the overspeed trip setting, the greater of these
two being used. If these requirements are not permissible the actual
overspeed percentage is to be agreed with the engine manufacturer
depending on application. The engine is to be run on no-load and the speed
at which this test is run is to be recorded. The overspeed trip is to be reset
and retested after this overspeed test is completed.
Note: It can be detrimental to run a diesel in an overspeed condition for a
prolonged period. DEF STAN 07−55 or the relevant NES provide guides
to acceptable vibration limits.
19. NES 362
Issue 3 (Reformatted)
2.5
(2) Gas Turbines
For each gas turbine driven auxiliary the output turbine disconnected
from the dynamometer or auxiliary, is to be run at not less than 15% in
excess of the maximum continuous speed or 5% above the approved
overspeed emergency trip speed, whichever is the greater, for not less than
10 minutes continuously. Where engines have a separate gas generator
line the gas generator is to be run at not less than 10% in excess of the gas
generator speed corresponding with the maximum specified duty for not
less than 10 minutes continuously.
Notes:
1. It may be neither practical nor permissible to run the gas turbine driven
auxiliary at these speeds and the actual permitted percentage overspeed
to be used for this test is to be agreed with the turbine or auxiliary
manufacturer.
2. Turbo feed-pumps, turbo generators and main turbines, as fitted in
submarines, have emergency overspeed trip arrangements.
g. Performance characteristic tests: each equipment is to be tested to establish its
consumption and output over the full range of operating conditions, including
the performance characteristics defined inthe instructions issued by MOD(PE).
During performance testing, if it is found necessary to adjust control and safety
devices, the tests specified for these are to be repeated under appropriately
revised conditions.
h. Noise vibration and shock tests: to conform to NES 811, NES 2020−2028, DGS
591, DGS 10008, DGS 10009 and BR 3021 and 3028.
i. Air pressure tests: the airbell enclosure of an equipment which is required to be
tested when submerged is to be subjected to an internal air pressure prior to
submergence. The air pressure is to be equivalent to the depth of submergence
and it is to be demonstrated by means of a sensitive gauge or manometer that
no leakage will occur during a minimum period of one hour. Suitable closure
plates are to be manufactured and used as required.
j. Submerged tests: when an equipment is to be capable of operation under
submerged conditions, tests are to demonstrate its capability to meet the
requirements. See also NES 1004.
k. Ambient tests: when an equipment is to operate under ambient conditions, tests
are to demonstrate its capability to meet the requirements. See also NES 1004.
l. Inclined tests: tests are to demonstrate the capability of the equipment to start,
stop and operate when inclined over the full range of output. Tests are normally
to be conducted at the inclination (or inclinations) in that direction which
imposes the most severe operating conditions. The length of test will be stated
in the procurement specification relevant to the equipment. See also NES 1004.
20. NES 362
Issue 3 (Reformatted)
2.6
m. Endurance tests: the equipment is to be run for a period, including all other test
running, of not less than 100 hours or more than 1000 hours, but the MOD may
choose to extend their period if considered necessary. The running time will be
determined having regard to experience of similar equipment, operational
requirements of the equipment and test facilities available. The total running
time is to be completed without mechanical defect or undue wear. During this
test a record is to be made of consumption of lubricating oil and fuel oil if
appropriate. The balance of time required to complete the endurance trial, after
completion of earlier type testing, is to comprise a series of operation cycles,
each one to simulate that likely to be met in service and to include where
applicable:
(1) Starting.
(2) Stopping.
(3) Idling or minimum power for a defined time.
(4) Full Power.
(5) Rapid increases of power.
(6) Rapid reductions of power.
(7) Reversals of direction of rotation.
(8) Astern power.
(9) Operation at fractions of power ahead.
(10) Operation at fractions of power astern.
n. Examination for wear: on completion of type test the equipment isto be stripped
and examined. All critical dimensions are to be recorded and divergence from
the original noted. Any wear observed is to be described and recorded and
photographic records of unusual wear or defects are to be provided. MOD(PE)
will advise when any particular examinations are required. Every equipment
embodying a rotor with fitted blades is to be opened up for examination of the
blading after completion of the overspeed test. After refurbishing the
equipment is to be subjected to production tests.
o. Assessment of Work Content of Scheduled Maintenance Operations: facilities
may be required for MOD(PE) representatives to witness, during or after type
tests, some or all of the scheduled maintenance operations to assess their work
content. Obstructions to simulate space limitations around the machine in the
ship are to be provided.
2.4 Results of Type Tests
a. The equipment manufacturer is to prepare four copies of the type test results
in a form agreed by MOD(PE). The report is to include the following
information:
(1) Date of report.
(2) Date of tests.

requirements. Where the equipment does not fully comply, a statement
that it has complied apart from the exceptions described.
(10) An indication of any deficiencies in operation arising out of the type
testing programme and suggested modifications which would improve
design and performance, whether or not such deficiencies are within the
scope of the specification or test requirements. These deficiencies and
suggestions are to be noted in the report.
(11) The modification state of the equipment during the type test.
(12) Certification by the maker that the test has been conducted in accordance
with the type test requirements.
(13) Type test results are to include tolerances for acceptable standards for
later production tests.
