The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in
8、a subject for which 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 Commissi
9、on (IEC) on all matters 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 c
10、ommittees are circulated 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 n

This European Standard shall be given the status of a national standard, either by publication of an identical text or by endors
19、ement, at the latest by June 2004, and conflicting national standards shall be withdrawn at the latest by December 2005.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. System St
20、andards are based on the results of the work being 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
21、 references are made throughout the System Standard. The System Standards are consistent with general standards on functional requirements and recommended practices for installation.

28、 2003 All rights reserved Introduction The System Standard of which this is Part 3, specifies the requirements for a piping system when made from polypropylene (PP). The piping system is intended to be used for hot and cold water installations. In respect of potential adverse effects on the quality
29、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 E
30、uropean criteria, existing national regulations concerning the use and/or the characteristics of this product remain in force. Requirements and test methods for materials and components, other than fittings, are specified in Part 1 and Part 2 of EN ISO 15874:2003. Characteristics for fitness for pur
31、pose (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 the fittings. ISO 15874-3:2003(E) ISO 2003 All rights reserved 1 1 Scope This Part of EN ISO 15874 specifies th
32、e characteristics of fittings for polypropylene (PP) piping systems intended to be used for hot and cold water installations 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
33、according to the class of application (see Table 1 of EN ISO 15874-1:2003). This standard covers a range of service conditions (application classes) and design pressure classes. For values of TD, Tmax and Tmal in excess of those in Table 1 of Part 1, this standard does not apply. NOTE It is the resp
34、onsibility 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 parameters for the test methods referred to in this stand
35、ard. In conjunction with the other parts of EN ISO 15874 (see Foreword) it is applicable to fittings made from PP and to fittings made from other materials which are intended to be fitted to pipes conforming to EN ISO 15874-2 for hot and cold water installations and whereby the joints conform to the
36、 requirements of EN ISO 15874-5. It is also applicable to fittings made from alternative materials which when fitted to pipes conforming to Part 2, conform to the requirements of Part 5 of EN ISO 15874. This standard is applicable to fittings of the following types: socket fusion fittings electrofus
