DIN CEN ISO/TS 21003-7:2010-12

This document is a new edition of Technical Specification DIN ISO/TS 21003-7. This contains methods for the verification of conformity for multilayer piping systems and their components, intended to be used in piping systems which are used for hot and cold water installations within buildings, whether or not the water is intended for human consumption (domestic systems) and for heating systems. This new edition takes into account Amendment 1 of the underlying International Technical Specification ISO/TS 21003-7:2008, which has been published separately by ISO as ISO/TS 21003-7:2008/Amd 1:2010. The subject of the amendment is the supplementary specifications for delamination testing within the framework of the batch release test (BRT) and the audit test (AT). The International Amendment has been prepared by ISO/TC 138/SC 2/WG 6 "Plastic pipes and fittings for water supplies - Reinforced polyolefin piping systems" (secretariat: NBN, Belgium). The corresponding initiative came from the German Mirror Committee, the Joint Subcommittee NA 119-04-06-06 GUA "Kunststoffrohre in der Trinkwasserversorgung - Mehrschichtrohrsysteme" ("Plastic pipes in the drinking water supply - Multilayer piping systems").
