ISO/TC 45/SC 2

Projekta Nr.ISO 48:2010
Nosaukums<p>ISO 48:2010 specifies four methods for the determination of the hardness of vulcanized or thermoplastic rubbers on flat surfaces (standard-hardness methods) and four methods for the determination of the apparent hardness of curved surfaces (apparent-hardness methods). The hardness is expressed in international rubber hardness degrees (IRHD). The methods cover the hardness range from 10 IRHD to 100 IRHD.</p> <p>These methods differ primarily in the diameter of the indenting ball and the magnitude of the indenting force, these being chosen to suit the particular application. </p> <p>ISO 48:2010 does not specify a method for the determination of hardness by a pocket hardness meter, which is described in ISO 7619‑2.</p> <p>ISO 48:2010 does not specify the determination of the apparent hardness of rubber-covered rollers, which is specified in ISO 7267 (all parts).</p>
