Rubber, vulcanized or thermoplastic. Resistance to ozone cracking - Reference and alternative methods for determining the ozone concentration in laboratory test chambers Ingestion-build-183098 Annex A (informative) Preferred designs1 Scope This document describes three types of method for the determination of ozone concentration in laboratory test chambers. Method A UV absorption: this is the reference method, and 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
