Rubber-covered rollers. Determination of apparent hardness - IRHD methodBS ISO 7267 1: 2008 Rubber covered rollers. Determination of apparent hardness. IRHD method BS ISO 7267 1 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 BS ISO 48 in that it consists essentially of measuring the depth
