BRITISH STANDARD BS EN ISO 15875-32003 Plastics piping systems for hot and cold water installations Crosslinked polyethylene PE-X Part 3 Fittings The European Standard EN ISO 15875-32003 has the status of a British Standard ICS 23.040.45; 91.140.60 Licensed Copy Institute Of Technology Tallaght, Institute of Technology, Tue Dec 19 095400 GMT0000 2006, Uncontrolled Copy, c BSI BS EN ISO 15875-32003 This British Standard was published under the authority of the Standards Policy and Strategy Committee on 14 June 2004 BSI 14 June 2004 ISBN 0 580 43885 6 National foreword This British Standard is the official English language version of EN ISO 15875-32003. It is identical with ISO 15875-32003. The UK participation in its preparation was entrusted by Technical Committee PRI/88, Plastics piping systems, to Subcommittee PRI/88/2, Plastics piping systems for pressure applications, which has the responsibility to A list of organizations represented on this subcommittee can be obtained on request to its secretary. Additional ination The UK voted against the acceptance of this standard at the CEN al Vote, and PRI 88/2 will maintain BS 7291-120011, BS 7291-220012 and BS 7291-320013 and strongly recommends the continued use of polybutylene PB and crosslinked polyethylene PE-X piping systems certified to BS 7291-2 or BS 7291-3, Class S, for the following reasons. a Attention is drawn to the statement in the Scope of BS EN ISO 15875-1 relating to the exclusion from it of piping systems having service conditions in excess of those quoted in BS EN ISO 15875-1, Table 1. Central heating systems in the UK fall into this category. BS 7291-1 states the service conditions for UK systems where the maximum system service temperature for sealed central heating systems, designated as Class S, is 105 C and the system malfunction temperature is 114 C. Both these temperatures are significantly in excess of those specified in BS EN ISO 15875-1, Table 1 and these UK systems are therefore not covered by this standard. aid enquirers to understand the text; present to the responsible international/European committee any enquiries on the interpretation, or proposals for change, and keep the UK interests ined; monitor related international and European developments and promulgate them in the UK. 1BS 7291-12001, Thermoplastics pipes and associated fittings for hot and cold water for domestic purposes and heating installations in buildings Part 1 General requirements. 2BS 7291-22001, Thermoplastics pipes and associated fittings for hot and cold water for domestic purposes and heating installations in buildings Part 2 Specification for polybutylene PB pipes and associated fittings. 3BS 7291-32001, Thermoplastics pipes and associated fittings for hot and cold water for domestic purposes and heating installations in buildings Part 3 Specification for cross-linked polyethylene PE-X pipes and associated fittings.

Consequently piping systems could be subjected to temperatures in service for which they have not been tested. 4 The unique and traditional practice in the UK is to use products certified to BS 7291-2 or BS 7291-3, Class S, for all applications, as defined in BS 7291-1. This is recognized in the national annex to BS EN 128288, which recommends the use of systems suitable for the maximum temperatures and pressures for their intended application specified in BS 7291-1. Updated versions of BS 7291-1, BS 7291-2 and BS 7291-3 are being prepared, which maintain these traditional UK operating conditions, and measures are being taken to address this issue in appropriate harmonized European Standards.

“Plastics piping systems and ducting systems”, the secretariat of which is held by NEN, in collaboration with Technical Committee ISO/TC 138 “Plastics pipes, fittings and valves for the transport of fluids“. This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by June 2004, and conflicting national standards shall be withdrawn at the latest by December 2005. NOTE This draft was ted for CEN enquiry as prEN 12318-31996. This standard is 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 being undertaken in ISO/TC 138 “Plastics pipes, fittings and valves for the transport of fluids“, which is a Technical Committee of the International Organisation for Standardization ISO. They are supported by separate Standards on test s to which references are made throughout the System Standard. The System Standards are consistent with general standards on functional requirements and recommended practices for installation. EN ISO 15875 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 the present standard Part 5 Fitness for purpose of the system Part 7 Guidance for the assessment of conity published as CEN ISO/TS 15875-7.
