    22、l 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. Internation

    23、al 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 the rules

    24、 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 by at le

ISO shall not be held responsible for identifying any or all such patent rights. ISO 21003-2 was prepared by Technical Committee ISO/TC

    26、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: General

    28、dIntroduction The system Standard, of which this is Part 2, 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 f

    29、or 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 European criteria, e

    30、xisting national regulations concerning the use and/or the characteristics of this product stay in force. Requirements and test methods for material and components, other than pipes, are specified in ISO 21003-1 and ISO 21003-3 of the ISO 21003-series. Characteristics for fitness for purpose (mainly

    31、 for joints) are covered in 21003-5. CEN ISO/TS 21003-7 gives guidance for the assessment of conformity. This part of ISO 21003 specifies the characteristics of pipes. At the date of publication of this standard, System Standards for piping systems of plastics materials used for the same application

    32、 are stated in Annex A. SANS 21003-2:2008This standard may only be used and printed by approved subscription and freemailing clients of the SABS.FINAL DRAFT INTERNATIONAL STANDARD ISO/FDIS 21003-2:2007(E) ISO 2007 All rights reserved 1Multilayer piping systems for hot and cold water installations in

    33、side buildings Part 2: Pipes 1 Scope This part of ISO 21003 specifies the characteristics of pipes for 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

    34、for heating systems, under design pressures and temperatures appropriate to the class of application (see Table 1 of ISO 21003-1). It also specifies the test parameters for the test methods referred to in this standard. Part 2 of the ISO 21003-series is one part of a reference product standard. This

    35、 series is applicable to multilayer 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 in conjunction with all other parts of ISO 21003. This standard covers a range of service conditions (

    36、application classes) and design pressures. For values of 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 requirement

    37、s and any relevant national regulations and installation practices 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 po

    38、ly(vinyl chloride) (PVC-C). NOTE For the purpose of this 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 pi

    39、pes with thin outer layers (e.g. as a protection layer 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 Norm
