16、 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 committee. Int
17、ernational 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 with t
18、he 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 approval
19、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 21003-5 was prepared by Technical Committee
20、 ISO/TC 138, Plastics pipes, fittings and valves for the transport of fluids, Subcommittee SC 2, Plastics pipes and fittings for water supplies. ISO 21003 consists of the following parts, under the general title Multilayer piping systems for hot and cold water installations inside buildings: Part 1:

22、tem Standard, of which this is Part 5, specifies the requirements for a multilayer piping system. The multilayer piping system is intended to be used for hot and cold water installations inside buildings. In respect of potential adverse effects on the quality of water intended for human consumption,
23、 caused by the product covered by ISO 21003: 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 regulati
24、ons concerning the use and/or the characteristics of this product stay in force. Requirements and test methods for components of the piping systems are specified in ISO 21003-1, ISO 21003-2 and ISO 21003-3 of the ISO 21003-series. CEN ISO/TS 21003-7 gives guidance for the assessment of conformity. T
25、his part of ISO 21003 specifies the characteristics for fitness for purpose. NOTE ISO 21003 does not incorporate a Part 4 Ancillary equipment or a Part 6 Guidance for installation. For ancillary equipment separate standards can apply. A guidance for installation for multilayer piping systems made fr

28、racteristics for the fitness for purpose of multilayer piping systems intended to be used for hot and cold water installations inside buildings for the conveyance of water whether or not intended for human consumption (domestic systems) and for heating systems, under design pressures and temperature
29、s according to the class of application (see Table 1 of ISO 10508). It also specifies the test parameters for the test methods referred to in this standard. Part 5 of the ISO 21003-series is one part of a reference product standard. This series is applicable to multilayer pipes, fittings, their join
30、ts and to joints with components of other plastics and non-plastics materials intended to be used for hot and cold water installations in conjunction with all other parts of ISO 21003. This standard covers a range of service conditions (application classes) and design pressures. For values of T D ,

32、ces or codes. The polymeric materials used for the stress designed layers are the following: polybutylene (PB), polyethylene of raised temperature resistance (PE-RT), crosslinked polyethylene (PE-X), polypropylene (PP) and chlorinated poly(vinyl chloride) (PVC-C). NOTE For the purpose of this Intern
33、ational Standard crosslinked polyethylene (PE-X) as well as adhesives are to be considered as thermoplastic materials. PE-X shall be crosslinked and shall comply with the requirements of the reference product standard. 2 Normative references The following referenced documents are indispensable for t
