9、ganization 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 a technical committee has been establ
10、ished 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 matters of electrotechnical standardizati
11、on. 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 circulated to the member bodies for voting.
12、 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 responsible for identifying any or all such pa

19、nt (EN ISO 15874-5:2003) has been prepared by Technical Committee CEN/TC 155 “Plastics piping systems and ducting systems”, the secretariat of which is held by NEN, in collaboration with Technical Committee ISO/TC 138 “Plastics pipes, fittings and valves for the transport of fluids“. NOTE This draft
20、 was submitted for CEN enquiry as prEN 12202-5:1995. 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of an identical text or by endorsement, at the latest by June 2004, and conflicting national standards shall be withdrawn at the latest by December 2005
21、. 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 work undertaken in ISO/TC 138 “Plastics pipes, fittings and valves for the tran
22、sport 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 Standard. The System Standards are consistent with general standards on functional
23、 requirements and recommended practices for installation. EN ISO 15874:2003 consists of the following Parts 1), under the general title Plastics piping systems for hot and cold water installations Polypropylene (PP) Part 1: General Part 2: Pipes Part 3: Fittings Part 5: Fitness for purpose of the sy

The pi
31、ping 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 EN ISO 15874; This standard provides no information as to whether the product may be used without
32、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 characteristics of this product remain in force. Requirements and test methods for components o
33、f the piping system are specified in Part 1, 2 and 3 of this System Standard. Part 7 (CEN ISO/TS) gives guidance for the assessment of conformity. This Part of EN ISO 15874 specifies the characteristics of fitness for purpose of the piping systems. Copyright International Organization for Standardiz

35、 characteristics of the fitness for purpose of 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 an
36、d temperatures according to the class of application (see Table 1 of EN ISO 15874-1:2003). This standard covers a range of service conditions (classes of application) 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. N
37、OTE It 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 regulations and installation practices or codes. It also specifies the test parameters for the test methods re
38、ferred to in this standard. In conjunction with the other Parts of EN ISO 15874 (see Foreword) it is applicable to PP pipes, fittings, their joints and to joints with components of other plastics and non-plastics materials intended to be used for hot and cold water installations. 2 Normative referen
