COMPRESSION SET
Description
Applications in which the rubber will be subjected to compressive stresses in air or liquid media.
METHOD A: CONSTANT FORCE IN AIR
METHOD B: CONSTANT DEFLECTION IN AIR
Choice between methods is optional, however Method B must be adopted unless otherwise stated.
Method B is NOT suitable for vulcanized harder than 90 IRHD.
Intended to measure the ability of rubber compounds to retain elastic properties after prolonged action of compressive stresses. Compression set tests are mainly applicable to service conditions involving static stresses.
Tests are usually performed at high temperatures.
