19、t of fluids“.This Technical Specification can be used to support elaboration of national third party certification procedures forproducts conforming to the applicable Part(s) of EN ISO 15876.This Technical Specification is a Part of a System Standard for plastics piping systems of a particular mater
20、ial for aspecified application. There are a number of such System Standards.System Standards are based on the results of the work undertaken in ISO/TC 138 “Plastics pipes, fittings andvalves for the transport of fluids“, which is a Technical Committee of the International Organization forStandardiza
21、tion (ISO).They are supported by separate standards on test methods to which references are made throughout the SystemStandard.The System Standards are consistent with general standards on functional requirements and on recommendedpractice for installation.This series consists of the following Parts
