2. BOX COMPRESSION STRENGTH TESTER- DIGITAL
‘PACORR’ Compression Strength Tester for transport packages is fabricated out of rigid mild steel
sections and plates. The lower platen on which the box is kept for pressing is fixed on the frame of the
tester. The package under test is placed over this platen and pressed down from top with the help of another
platen. The upper platen is moved down by means of a screw arrangement. This platen is pivoted so that is
can tilt to align its lower face with the top of the package, if the top and bottom faces of the package are not
parallel. For conducting the edge and corner loading tests the upper platen can be held rigidly so that it does
not tilt.
The load cell used for measurement of compressive force acting on the package under test is mounted above
the upper platen. The load is indicated on a microprocessor based digital indicator. The load indicator has
peak force memory to indicate the maximum load at which the package failed, and a relay with overload
protection to stop the motor if the load exceeds the maximum capacity of the load cell.
The movement to the upper platen is given through a motor and gearbox arrangement. The distance moved
by the upper platen is indicated on a separate digital display capable of measuring the distance to the nearest
1 mm. The equipment has over-travel protection arrangement to stop the motor at extreme limits of platen
movement.

time is determined, from which the sizing characteristic is evaluated. However, this method is not
recommended for determination of sizing characteristic of writing paper.

area fitted on a swinging plate, a steel back up plate lined with a sheet of rubber, and a clamping bar to
clamp the backup plate on the specimen placed over the reservoir.

reservoir and is held over a flat metallic base. The base also has a provision for placing the test specimen
on a stainless steel lined flat surface for rolling after exposure to water.

10. ELMENDORF TEARING TESTER
The tearing strength of fabrics, papers, plastic films, or other similar materials in sheet form is determined
by measurement of work done in tearing through a fixed length of the test specimen using the Elmendorf
tear tester.
Pacorr Elmendorf Tearing Tester consists of a brass sector pendulum pivoted on low-friction ball
bearings over a vertical bracket fixed on a rigid metallic base. The test specimen, in shape of a rectangle, is
held between two clamps, one of which is mounted on the pendulum and the other is mounted on the vertical
bracket. The clamps are mounted in such a manner that their holding faces are aligned with each other when
the pendulum is locked in its raised position. The pendulum is released by lifting a release lever. This action
causes the pendulum to fall down under its weight and to tear the test specimen while doing so. The energy
absorbed during tearing is indicated on a scale fitted on the pendulum by a low friction pointer pivoted on
the axis of the pendulum.
An adjustable knife is also mounted on the pendulum support bracket. It is centered between the two clamps
and is used for making the initial slit in the test specimen.
A check weight is supplied with the tester for verification of the scale.
The apparatus is finished in shore blue metallic painting and bright chrome plating to give it a corrosion
resistant finish.
Augmenting weights for increasing the range of the tester for testing high strength materials are available
as optional accessories. Low strength materials can be tested by mounting multiple specimens at the same
time.

12. Vibration Table
Vibration test is not only desired for products used in grueling working circumstances and being looked
on as the environmental test in the distribution routes. It is because that the effect of shock in transit
having on products is to such an extent that they deteriorate progressively and it often leads products
unusable. Needless to say, ordinary products are mostly put in far severer conditions in the distribution
routes than in their working condition.
The test method simulated the conditions occur on a package during transit and is an effective
equipment for package design and performance analysis before production and use.
