ISO 815-1 describes laboratory methods for the compression set of vulcanized and thermoplastic rubber at ambient and elevated temperatures. To match this to your program, talk with our team.
What ISO 815-1 Covers
It measures the permanent deformation remaining after a rubber specimen is held compressed, characterizing recovery and sealing performance.
How the Test Is Run
A specimen is compressed to a set deflection in a jig, held at the test temperature for a defined time, released, and the residual set is measured after recovery.
Why It Matters
Compression set governs seal and gasket longevity; controlled compression fixtures and accurate thickness measurement are used.
