9、n) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be rep
10、resented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards a
11、re drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an Internatio
12、nal Standard requires approval by at least 75 % of the member bodies casting a vote. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. ISO 15875-2 was
13、prepared by the European Committee for Standardization (CEN) in collaboration with Technical Committee ISO/TC 138, Plastics pipes, fittings and valves for the transport of fluids, Subcommittee SC 2, Plastics pipes and fittings for water supplies, in accordance with the Agreement on technical coopera
14、tion between ISO and CEN (Vienna Agreement). Throughout the text of this document, read “.this European Standard.” to mean “.this International Standard.”.

21、ics pipes, fittings and valves for the transport of fluids“. NOTE This draft was submitted for CEN enquiry as prEN 12318-2:1996. 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 conf
22、licting national standards shall be withdrawn at the latest by December 2005. 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 wor
23、k 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 Standa
24、rd. 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)
25、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 15875-7).

For ancillary equipment separate s
29、tandards 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 12108:2001 1.

33、he System Standard, of which this is Part 2, specifies the requirements for a piping system when made from crosslinked polyethylene (PE-X). 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 huma
34、n 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
35、 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 15875:2003. Characteristics for fitness for purpose (mainly for joints) are co
36、vered in Part 5. Part 7 (CEN ISO/TS 15875-7) gives guidance for the assessment of conformity. This Part of EN ISO 15875 specifies the characteristics of pipes.

39、lations within buildings for the conveyance of water, whether or not intended for human consumption (domestic systems), and for heating systems, under design pressures and temperatures appropriate to the class of application (see Table 1 of EN ISO 15875-1:2003). This standard covers a range of servi
40、ce conditions, (application classes), design pressures and pipe dimension classes. For values of TD, Tmax and Tmal in excess of those in Table 1 of Part 1, this standard does not apply. NOTE 1It is the responsibility of the purchaser or specifier to make the appropriate selections from these aspects
41、, 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 15875 (see Foreword) it is applicable
42、to PE-X pipes, their joints and to joints with components of PE-X, other plastics and non-plastics materials intended to be used for hot and cold water installations. It is applicable to pipes with or without (a) barrier layer(s). NOTE 2In the case of plastics pipes provided with a thin barrier laye
43、r, e.g. to prevent or greatly diminish the diffusion of gases and the transmission of light into or through the pipe wall, the design stress requirements are totally met by the base polymer (PE-X). 2 Normative references This Standard incorporates by dated or undated reference, provisions from other
44、 publications. These normative references are cited at the appropriate places in the text and the publications are listed hereafter. For dated references, subsequent amendments to or revisions of any of these publications apply to this Standard only when incorporated in it by amendment or revision.
