18、bscription and freemailing clients of the SABS.ISO/FDIS 21003-3:2007(E) iv ISO 2007 All rights reservedForeword ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normal
19、ly 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. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the
20、 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 given in the ISO/IEC Directives, Part 2. The main task of technical committees is to prepare I
21、nternational 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 o
22、f 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 21003-3 was prepared by Technical Committee ISO/TC 138, Plastics pipes, fittings and valves for the transport of fluids, Subcommittee SC 2, Plasti
23、cs 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 Part 2: Pipes Part 3: Fittings Part 5: Fitness for purpose of the system Part 7: Guidance for
24、the assessment of conformity SANS 21003-3:2008This standard may only be used and printed by approved subscription and freemailing clients of the SABS.ISO/FDIS 21003-3:2007(E) ISO 2007 All rights reserved vIntroduction The system Standard, of which this is Part 3, specifies the requirements for a mul
25、tilayer 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 ISO 21003. This Standard provides no info
26、rmation 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 this product stay in f
27、orce. Requirements and test methods for materials and components, other than fittings,are specified in ISO 21003-1 and ISO 21003-2 of the ISO 21003 series. Characteristics for fitness for purpose (mainly for joints) are covered in ISO 21003-5. CEN ISO/TS 21003-7 gives guidance for the assessment of
28、conformity. This part of ISO 21003 specifies the characteristics of fittings.

30、g 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 temperatures appropriate to the class of application (see Table 1 of IS
31、O 21003-1). It also specifies the test parameters for the test methods referred to in this standard. Part 3 of the ISO 21003-series is one part of a reference product standard. This series is applicable to multilayer pipes, fittings, their joints and to joints with components of other plastics and n
32、on-plastics materials intended to be used for hot and cold water installations in conjunction with all other parts of ISO 21003. This standard covers fusion, solvent cemented and mechanical fittings and a range of service conditions (application classes) and design pressures. For values of T D , T m

34、 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 Internati
35、onal 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 the
