Rubber, vulcanized or thermoplastic. Determination of hardness - Apparent hardness of rubber-covered rollers by IRHD method1 Scope This document specifies a method for the determination of the apparent hardness, expressed in International Rubber Hardness Degrees (IRHD), of vulcanized or thermoplastic rubber roller covers. The method is similar in principle to the methods used for the determination of the hardness of rubber in ISO 482 in that it consists essentially of measuring the depth of penetration of a spherical indentor operating under a specified force. The
