适用范围：This part of ISO 7267 specifies a method for the determination of the apparent hardness, expressed inInternational Rubber Hardness Degrees (IRHD), of vulcanized- or thermoplastic-rubber roller covers. Themethod is similar in principle to the methods used for the determination of the hardness of rubber in ISO 48 inthat it consists essentially of measuring the depth of penetration of a spherical indentor operating under aspecified force. The apparatus used is similar to that described in ISO 48, having a base specifically designedfor application to roller covers and similar curved surfaces.NOTE With some rollers, there may be significant variation in the thickness of the rubber over the surface of theroller, which could affect the measured apparent hardness.
