ISO International Standard

ISO 7743:2017 specifies methods for the determination of the compression stress-strain properties of vulcanized or thermoplastic rubber using a standard test piece, a product or a part of a product.

Four procedures are given:

– using standard test piece A with the metal plates lubricated (method A);

– using standard test piece A with the metal plates bonded to the test piece (method B);

– using standard test piece B (method C);

– using a product or a part of a product with the metal plates lubricated (method D).

The methods are not suitable for materials that exhibit high set.
