BS ISO 7743Rubber, vulcanized or thermoplastic. Determination of compression stress-strain properties
ISO 7743 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).
Before conducting ISO 7743, it is important to read the entire specification. Standards can be obtained from appropriate standard authorities.
