16、iiiForeword ISO (the International Organization for Standardization) 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
17、a technical committee has been established has the right to be represented 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 matt
18、ers of electrotechnical standardization. International Standards are 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 circul
19、ated to the member bodies for voting. Publication as an International 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 responsib
20、le for identifying any or all such patent rights. ISO 15876-2 was 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 wat
21、er supplies, in accordance with the Agreement on technical cooperation between ISO and CEN (Vienna Agreement).

38、 of the EU or EFTA; It should be noted that, while awaiting the adoption of verifiable European criteria, existing national regulationsconcerning the use and/or the characteristics of this product remain in force.Requirements and test methods for material and components, other than pipes, are specif
39、ied in Part 1 and Part 3of EN ISO 15876:2003. Characteristics for fitness for purpose (mainly for joints) are covered in Part 5. Part 7 (CENISO/TS 15876-7) gives guidance for the assessment of conformity.This Part of EN ISO 15876 specifies the characteristics of pipes.ISO 15876-2:2003(E) ISO 2003 Al
40、l rights reserved 11 ScopeThis Part of EN ISO 15876 specifies the characteristics of pipes made of polybutylene (PB) for piping systemsintended to be used for hot and cold water installations within buildings for the conveyance of water whether or notintended for human consumption (domestic systems)
41、, and for heating systems, under design pressures andtemperatures appropriate to the class of application (see Table 1 of EN ISO 15876-1:2003).This standard covers a range of service conditions (application classes), design pressures and pipe dimensionclasses. For values of TD, Tmaxand Tmalin excess
42、 of those in Table 1 of 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 theirparticular requirements and any relevant national regulations and installation practices or codes
43、.It also specifies the test parameters for the test methods referred to in this standard.In conjunction with the other Parts of EN ISO 15876 (see Foreword) it is applicable to PB pipes, their joints and tojoints with components of PB, other plastics and non-plastics materials intended to be used for
44、 hot and cold waterinstallations.It is applicable to pipes with or without (a) barrier layer(s).NOTE 2 In the case of plastics pipes provided with a thin barrier layer, e.g. to prevent or greatly diminish the diffusion of gases and thetransmission of light into or through the pipe wall and where the
45、 design stress requirements are totally met by the base polymer (PB).2 Normative referencesThis standard incorporates by dated or undated reference, provisions from other publications.
