Abstract
Overview
ISO 4433-2:1997 - Thermoplastics pipes - Resistance to liquid chemicals - Classification - Part 2: Polyolefin pipes - defines a laboratory classification system for the chemical resistance of polyolefin pipes (PE, PP, PB, PE-X) and applicable sheets. It is intended for assessing pipe material behaviour when immersed in liquids in the absence of pressure or external stress. The method is based on measured changes in mass and mechanical properties after immersion (immersion tests follow ).
