This document 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.
