This can cause brittleness and may lead to cracks in the wire

as covered in the companion standard BS EN ISO 1101

Test-sieving machines are used for determining the size distribution of bonded and coated abrasive macrograins

These measurements need to be reproducible and independent of conditions other than those being recorded and documented

Rubber, vulcanized or thermoplastic. Resistance to ozone cracking - Reference and alternative methods for determining the ozone concentration in laboratory test chambers Ingestion-build-251241 This can cause brittleness and1 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
