DIN ISO 34-1
Rubber, vulcanized or thermoplastic - Determination of tear strength - Part 1: Trouser, angle and crescent test pieces (ISO 34-1:2015)
Elastomere oder thermoplastische Elastomere - Bestimmung des Weiterreißwiderstandes - Teil 1: Streifen-, winkel- und bogenförmige Probekörper (ISO 34-1:2015)
Overview
This standard has been prepared by Technical Committee ISO/TC 45 "Rubber and rubber products" (secretariat: DSM, Malaysia), SC 2 "Testing and analysis" (secretariat: JISC, Japan). The responsible German committee is Working Committee 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 part of ISO 34 specifies three test methods for the determination of the tear strength of vulcanized or thermoplastic rubber, namely the following: - method A, using a trouser test piece; - method B, using an angle test piece, with or without a nick of specified depth; - method C, using a crescent test piece with a nick. The value of tear strength obtained depends on the shape of the test piece, speed of stretching, and temperature of test. It can also be susceptible to grain effects in rubber.
