Rubber-covered rollers — Determination of apparent hardness — Part 2: Shore-type durometer method ISO 7267-2:2008

Publication date:   Jul 21, 2008

Scope

ISO 7267-2:2008 specifies a method for the determination of the apparent hardness of vulcanized- or thermoplastic-rubber roller covers, expressed in Shore hardness, for measurement where only medium precision is required. The method and apparatus used are essentially those described in ISO 7619‑1, the measurements in this case being made on the curved surface of the conditioned rubber-covered roller rather than on a flat test piece. Shore type A and type D instruments are specified, the latter being used for measurements on rollers of high hardness.
