9、ederation 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 co
10、mmittee. 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 accor
11、dance 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 requir

20、ion with Technical Committee ISO/TC 138 “Plastics pipes, fittings and valves for the transport of fluids“. NOTE This standard was submitted for CEN enquiry as prEN 12319-1:1996. This European Standard shall be given the status of a national standard, either by publication of an identical text or by
21、endorsement, at the latest by June 2004, and conflicting national standards shall be withdrawn at the latest by December 2005.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. Sys
22、tem 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 Organisation for Standardization (ISO). They are supported by separate standards on test methods to which
23、 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 15876 consists of the following Parts 1) under the general title: Plastics piping systems for hot and cold wat

32、roduct covered by EN ISO 15876: 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 concernin
33、g the use and/or the characteristics of this product remain in force. Requirements and test methods for components of the piping systems, are specified in Part 2 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 158
34、76-7) gives guidance for the assessment of conformity. This Part of EN ISO 15876 specifies the general aspects of the plastics piping system.

36、ns 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 according to the class of application (see Table 1). This standard covers a range of service conditions (application class
37、es) and design pressure and pipe dimension classes. For values of TD, Tmax and Tmal in excess of those in Table 1, this standard does not apply. NOTE It is the responsibility of the purchaser or specifier to make the appropriate selections from these aspects, taking into account their particular req
38、uirements 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 15876 (see Foreword) it is applicable to PB pipes, fittings, their joints and to
39、 joints with components of other plastics and non-plastics materials intended to be used for hot and cold water installations. 2 Normative references This Standard incorporates by dated or undated reference, provisions from other publications. These normative references are cited at the appropriate
