9、tion 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 represented on that committ
10、ee. 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 are drafted in accordance
11、 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 International Standard requires ap
12、proval 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 15876-2 was prepared by the European
13、 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 cooperation between ISO and CEN

21、t 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of an identical text or by endorsement, at the latest by June 2004, and conflicting national standards shall be withdrawn at the latest by December 2005.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 submitted for CEN
22、 enquiry as prEN 12319-2:1996. This standard is a 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, f
23、ittings 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 methods to which references are made throughout the System Standard. The System Standards are consistent with
24、general standards on functional requirements and recommended practices for installation.

25、 3: Fittings Part 5: Fitness for purpose of the system Part 7: Guidance for the assessment of conformity (CEN ISO/TS 15876-7). This Part of EN ISO 15876 includes the following: Annex A (informative): Derivation of Scalc,max; Bibliography. At the date of publication of this standard, System Standards
26、 for piping systems of other plastics materials used for the same application are the following: EN ISO 15874, Plastics piping systems for hot and cold water installations Polypropylene (PP) (ISO 15874:2003) EN ISO 15875, Plastics piping systems for hot and cold water installations Crosslinked polye

33、ecifies the requirements for a piping system when made from polybutylene (PB). 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
34、: 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 character
35、istics 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 15876:2003. Characteristics for fitness for purpose (mainly for joints) are covered in Part 5. Part 7 (CEN ISO/TS 15876-7) gives guidance
36、for the assessment of conformity. This Part of EN ISO 15876 specifies the characteristics of pipes.

38、-,-,- ISO 15876-2:2003(E) ISO 2003 All rights reserved 1 1 Scope This Part of EN ISO 15876 specifies the characteristics of pipes made of polybutylene (PB) for piping systems intended to be used for hot and cold water installations within buildings for the conveyance of water whether or not intended
39、 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 15876-1:2003). This standard covers a range of service conditions (application classes), design pressures and pipe dimension clas
40、ses. 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, taking into account their particular requirements and any relevant national
41、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 15876 (see Foreword) it is applicable to PB pipes, their joints and to joints with components of PB, other plastics
42、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 layer, e.g. to prevent or greatly diminish the diffusion of gases and the transmission
43、 of light into or through the pipe wall and where the design stress requirements are totally met by the base polymer (PB). 2 Normative references This standard incorporates by dated or undated reference, provisions from other publications. These normative references are cited at the appropriate plac
44、es in the text and the publications are listed hereafter. For dated subsequent amendments to, or revisions of, any of these publications apply to this standard only when incorporated in it by amendment or revision.
