This Technical Specification can be used to support elaboration of national third party certification procedures for products conforming to the applicable Part(s) of EN ISO 15875. This 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 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 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 Crosslinked polyethylene (PE-X) Part 1: General Part 2: Pipes Part 3: Fittings Part 5: Fitness for purpose of the system Part 7: Guidance for the assessment of conformity (this Technical Specification) This Technical Specification includes a bibliography. At the date of publication of this Technical Specification, System Standards for piping systems of other plastics materials used for the same application are the following: EN ISO 15874, Plastics piping systems for hot and cold water installations Polypropylene (PP) EN ISO 15876, Plastics piping systems for hot and cold water installations Polybutylene (PB) EN ISO 15877, Plastics piping systems for hot and cold water installations Chlorinated poly(vinyl chloride) (PVC-C) According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to announce this Technical Specification: Austria, Belgium, Czech Republic, Denmark, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Luxembourg, Malta, Netherlands, Norway, Portugal, Slovakia, Spain, Sweden, Switzerland and the United Kingdom. 1) This System Standard does not incorporate Part 4: Ancillary equipment and Part 6: Guidance for installation. For ancillary equipment separate standards can apply. For guidance for installation reference is made to separate documents. NOTE A guidance for installation of plastics piping systems made from different materials, intended to be used for hot and cold water installations, is covered by ENV 121081.
