BRITISH STANDARD BS EN ISO 15874-2:2003 Plastics piping systems for hot and cold water installations Polypropylene (PP) Part 2: Pipes The European Standard EN ISO 15874-2:2003 has the status of a British Standard ICS 23.040.20; 91.140.60 ?

It is identical with ISO 15874-2:2003. 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 information The UK voted against the acceptance of this standard at the CEN Formal Vote, and PRI 88/2 will maintain BS 7291-1:20011), BS 7291-2:20012) and BS 7291-3:20013) 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 15874-1 relating to the exclusion from it of piping systems having service conditions in excess of those quoted in BS EN ISO 15874-1, 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 15874-1, 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 informed; monitor related international and European developments and promulgate them in the UK. 1)BS 7291-1:2001, Thermoplastics pipes and associated fittings for hot and cold water for domestic purposes and heating installations in buildings Part 1: General requirements. 2)BS 7291-2:2001, 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. 3)BS 7291-3:2001, 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.

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 1 This standard was submitted for CEN enquiry as prEN 12202-2:1995. 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 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 recommended practices for installation. EN ISO 15874 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 (the present standard) Part 3: Fittings Part 5: Fitness for purpose of the system Part 7: Guidance for the assessment of conformity (CEN ISO/TS 15874-7). This Part of EN ISO 15874 includes the following: Annex A (informative): Derivation of Scalc,max Bibliography At the date of publication of this standard, System Standards for piping systems of other plastics materials used for the same application are the following: EN ISO 15875, Plastics piping systems for hot and cold water installations Crosslinked polyethylene (PE-X) (ISO 15875:2003) EN ISO 15876, Plastics piping systems for hot and cold water installations Polybutylene (PB) (ISO 15876:2003) EN ISO 15877, Plastics piping systems for hot and cold water installations Chlorinated poly(vinyl chloride) (PVC-C) (ISO 15877:2003) For pipes and fittings which have conformed to the relevant national standard before 1st November 2003, as shown by the manufacturer or by a certification body, the national standard may continue to apply until 30th November 2005. According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: 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 a Part 4 Ancillary equipment or a Part 6: Guidance for installation. For ancillary equipment separate standards can apply. Guidance on installation of plastics piping systems made from different materials, intended to be used for hot and cold water installations, is given by ENV 12108 1.

The piping system is intended to be used for hot and cold water installations. In respect of potential adverse effects on the quality of water intended for human consumption, caused by the product covered by this standard: This standard provides no information as to whether the product may be used without restriction in any of the Member States of the EU or EFTA; It should be noted that, while awaiting the adoption of verifiable European criteria, existing national regulations concerning the use and/or the characteristics of this product remain in force. Requirements and test methods for material and components, other than pipes, are specified in Part 1 and Part 3 of EN ISO 15874:2003. Characteristics for fitness for purpose (mainly for joints) are covered in Part 5. Part 7 (CEN ISO/TS 15874-7:2003) gives guidance for the assessment of conformity. This part of EN ISO 15874 specifies the characteristics of pipes.

This standard covers a range of service conditions (application classes), design pressures and pipe dimension classes. For values of TD, Tmax and Tmal in excess of those in Table 1of Part 1, this standard does not apply. NOTE 1 It is the responsibility of the purchaser or specifier to make the appropriate selections from these aspects, taking into account their particular requirements and any relevant national regulations and installation practices or codes. It also specifies the test parameters for the test methods referred to in this standard. In conjunction with the other parts of EN ISO 15874 (see Foreword) it is applicable to PP pipes, their joints and to joints with components of PP, other plastics and non-plastics materials intended to be used for hot and cold water installations. It is appli
