The work of preparing International Standards is normally carried o
17、ut 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. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO c
18、ollaborates closely with the International Electrotechnical Commission (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
19、 Standards. Draft International Standards adopted by the technical committees 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 elemen
20、ts 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 21003-1 was prepared by Technical Committee ISO/TC 138, Plastics pipes, fittings and valves for the transport of fluids, Subcommittee SC 2, Plastics pipes and
21、 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: General Part 2: Pipes Part 3: Fittings Part 5: Fitness for purpose of the system Part 7: Guidance for the assessme
22、nt of conformity ISO 21003 does not incorporate a Part 4: Ancillary equipment and a Part 6: Guidance for installation. For ancillary equipment separate standards can apply. A guidance for installation for multilayer piping systems made from different materials, intended to be used for hot and cold w
23、ater installations, is covered by ENV 12108.

24、ements 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, caused by the product covered by this standard: This Stand
25、ard 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 characteristics of th
26、is product stay in force. Requirements and test methods for components of the piping system are specified in ISO 21003-2 and ISO 21003- 3 of the ISO 21003-series. Characteristics for fitness of purpose (mainly for joints) are covered in ISO 21003-5. CEN ISO/TS 21003-7 gives guidance for the assessme
27、nt of conformity. This part of ISO 21003 specifies the general aspects of the multilayer piping systems. At the date of publication of this standard, System Standards for piping systems of plastics materials used for the same application are stated in Annex A. SANS 21003-1:2008This standard may only

30、nded for human consumption (domestic systems) and for heating systems, under design pressures and temperatures according to the class of application (see Table 1). Part 1 of the ISO 21003-series is one part of a reference product standard. This series is applicable to multilayer pipes, fittings, the
31、ir joints 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
32、 T D , T maxand T malin 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 requirements and any relevant national regulations and installatio
33、n practices or codes. The polymeric materials used for the stress designed layers are the following: polyethylene of raised temperature resistance polybutylene (PB), (PE-RT), crosslinked polyethylene (PE-X), polypropylene (PP) and chlorinated poly(vinyl chloride) (PVC-C). NOTE For the purpose of thi
34、s International 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. NOTE Solid wall pipes with thin outer layers (e.g. as a protection layer
35、or a barrier layer) are not covered by ISO 21003 but are specified in the amendments of the ISO1587x-series. The total thickness of the outer layers, including the thickness of adhesives, barrier and/or protective layers, shall be 0.4 mm. 2 Normative references The following referenced documents are
