24、This document (EN ISO 15876-1:2003) has been prepared by Technical Committee CEN/TC 155 “Plastics pipingsystems and ducting systems”, the secretariat of which is held by NEN, in collaboration with Technical CommitteeISO/TC 138 “Plastics pipes, fittings and valves for the transport of fluids“.NOTE Th
25、is standard was submitted for CEN enquiry as prEN 12319-1:1996.This European Standard shall be given the status of a national standard, either by publication of an identical text orby endorsement, at the latest by June 2004, and conflicting national standards shall be withdrawn at the latest byDecem
26、ber 2005.This standard is Part of a System Standard for plastics piping systems of a particular material for a specifiedapplication. 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
27、transport of fluids“, which is a Technical Committee of the International Organisation 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
28、 requirements and recommendedpractices for installation.EN ISO 15876 consists of the following Parts 1) under the general title: Plastics piping systems for hot and coldwater installations Polybutylene (PB)Part 1: General (the present standard)Part 2: PipesPart 3: FittingsPart 5: Fitness for purpose
