20、aboration with Technical Committee ISO/TC 138 “Plastics pipes, fittings and valves for the transport of fluids“. This Technical Specification (TS) can be used to support elaboration of national third party certification procedures for products conforming to the applicable Part(s) of EN ISO 15874. Th
21、is Technical Specification is a Part of a System Standard for plastics piping systems of a particular material for a specified 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 and valves
22、 for the transport of fluids“, which is a Technical Committee of the International Organization for Standardization (ISO). They are supported by separate standards on test methods to which references are made throughout the System Standard. The System Standards are consistent with general standards
23、on functional requirements and on recommended practice for installation. This series consists of the following Parts 1), under the general title Plastics piping systems for hot and cold water installations Polypropylene (PP) Part 1: General Part 2: Pipes Part 3: Fittings Part 5: Fitness for purpose
