Rubber, vulcanized or thermoplastic - Determination of hardness (hardness between 10 IRHD and 100 IRHD) (ISO 48:2010)
Elastomere oder thermoplastische Elastomere - Bestimmung der Härte (Härte zwischen 10 IRHD und 100 IRHD) (ISO 48:2010)
Overview
This document contains the German translation of the International Standard ISO 48:2010 which has been prepared at Technical Committee ISO/TC 45 "Rubber and rubber products" (secretariat: DSM, Malaysia). The responsible national committee is NA 062-04-34 AA"Prüfung der physikalischen Eigenschaften von Kautschuk und Elastomeren" ("Test procedures for physical properties of rubber") at DIN Standards Committee Materials Testing (NMP). This International Standard 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. 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.
