19、 138 “Plastics pipes, fittings and valves for the transport 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 15875.This Technical Specification is a Part of a System
20、Standard for plastics piping systems of a particular material 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
21、Committee of the International Organization forStandardization (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 fo
