Repeated Compression Set Tester for Foam - For Testing Lab
Determination of change in thickness of Foam material due to repeated
compression encountered in their day-to-day use is of great importance
in determining their quality. Determination of this change is carried
out with the help of a Repeated Compression Set Tester. In this test a
test specimen taken from the material under test is compressed
repeatedly under simulated conditions of use and the effect of this
action on its thickness evaluated to determine the quality of the
material under test.
The Repeated Compression Set Tester for foam material is
designed to simulate the action of repeated pressings encountered in
use. It consists of an arrangement to give a vertical reciprocating
movement to two indentors held on two eccentric discs with the help of
an electric motor and reduction gearbox.
The movement of
the indentors can be adjusted so that they can give a compression equal
to 50% of the thickness of the test specimens. The height of the
indentors can be adjusted and they can be locked so that at the top of
their movement they just touch the top of the test specimens. The number
of repeated compression undergone is recorded on a pre-set type digital
counter with memory backup, which automatically stops the motor on
completion of the desired number of operations.
