Overview
This document contains the German translation of the International Standard ISO 1431-3:2000, which has been prepared by 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 the Petroleum, Fuels, Lubricants and Related Products Standardization Committee (NMP). A number of techniques exist for the analysis of gaseous ozone/air mixtures used for ozone crack testing of rubbers. These include wet-chemical procedures, electrochemical cells, UV absorption and chemiluminescence with ethylene. This part of DIN ISO 1431 specifies three methods for the determination of ozone concentration in laboratory test chambers. Method A - UV absorption: reference method which is used as the means of calibration for the alternative methods B and C. Method B - Instrumental techniques: B1: electrochemical B2: chemiluminescence. Method C - Wet-chemical techniques: Procedure I, Procedure II, Procedure III. condense
