DIN ISO 815-2:2016-09

This document contains the German translation of the International Standard ISO 815-1:2014 which has been prepared by Technical Committee ISO/TC 45 "Rubber and rubber products" (secretariat: DSM, Malaysia). The committee responsible for this standard 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 part of ISO 815 specifies two methods for the determination of the compression set characteristics of vulcanized and thermoplastic rubbers at low temperatures. Method 1 derives from the methodology used in ISO 815-1. Method 2 uses a specified testing device, allowing to measure and record the test piece thickness during recovery. Due to the load applied during recovery in method 2, no correlation can be established between the results given by both methods.
