2、as published under the authority of the Standards Policy and Strategy Committee on 30 September 2008 BSI 2008 ISBN 978 0 580 55370 7 National foreword This British Standard is the UK implementation of EN ISO 21003-1:2008. The UK participation in its preparation was entrusted by Technical Committee P
3、RI/88, Plastics piping systems, to Subcommittee PRI/88/2, Plastic piping for pressure applications. A list of organizations represented on this committee can be obtained on request to its secretary. The UK Committee would like to emphasise that compliance with this British Standard does not necessar
4、ily mean that products are fit for non-potable hot water pipes. The requirements contained in this standard are not necessarily indicative of all the performance requirements, or the suitability of pipework for the service conditions, likely to be encountered in a particular pipework application in
5、the UK. In particular: This standard does not replace BS 7291 parts 1, 2 and 3 (Class S) which contain detailed requirements for performance and contact with drinking water for pipes, fittings and joints manufactured from Polybutylene and PEX materials. (i)The normal maximum operating cold water sup
6、ply pressure in the UK is 12.5 bar, a pressure that some application classes of pipe in this standard do not meet. (ii)This standard does not specifically describe push-fit joints that are the predominant jointing method in the UK but defines mechanical fittings in general. (iii)There is a disparity
7、 between the malfunction temperature (100 C) quoted in Table 1 of Part 1 of this standard and the malfunction temperatures applicable to boilers (110 C) conforming to BS EN 297:1994, BS EN 483:2000 and BS EN 625:1996. Current UK practice can be found in BS 7291-1 which should be consulted when apply
8、ing this standard. Pipe systems not conforming to BS 7291-1 could be subjected to temperatures in service for which they have not been tested. (iv)The unique and traditional practice in the UK is to use products certified to BS 7291 Class S for all applications, as defined in BS 7291-1. This is reco
9、gnized in the National Annex to BS EN 12828 that requires the use of systems suitable for the maximum temperatures and pressures for their intended application specified in BS 7291-1.

29、08 03:09, Uncontrolled Copy, (c) BSI iv Introduction The system standard of which this is Part 1 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 potentially adverse eff
30、ects on the quality of water intended for human consumption caused by the products covered by ISO 21003: no information is provided as to whether the products 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 verifi
31、able European criteria, existing national regulations concerning the use and/or the characteristics of these products remain in force. Requirements and test methods for components of the piping system are specified in ISO 21003-2 and ISO 21003-3. Characteristics relating to fitness for purpose (main
32、ly for joints) are covered in ISO 21003-5. ISO/TS 21003-7 gives guidance on the assessment of conformity. This part of ISO 21003 specifies the general aspects of multilayer piping systems. For ancillary equipment, separate standards can apply. Guidance on installation of plastics piping systems made
33、 from various materials intended to be used for hot and cold water installations is given in ENV 12108. Other system standards which, at the date of publication of this part of ISO 21003, had been published for plastics piping systems used for the same application are listed in Annex A. BS EN ISO 21
34、003-1:2008 Licensed CopyChinese University of Hong Kong, 21/10/2008 03:09, Uncontrolled Copy, (c) BSI 1 Multilayer piping systems for hot and cold water installations inside buildings Part 1: General 1 Scope This part of ISO 21003 specifies the general aspects of multilayer piping systems intended t
35、o be used for hot and cold water installations inside buildings for the conveyance of water whether or not the water is intended for human consumption (domestic systems) or heating systems under specified design pressures and temperatures appropriate to the class of application (see Table 1). ISO 21
36、003 is a reference product standard (see 3.4.3). It is applicable to multilayer pipes, fittings, their joints, and also to joints with components made of other plastics and non-plastics materials intended to be used for hot and cold water installations. This part of ISO 21003 is intended for use onl
37、y in conjunction with all the other parts of ISO 21003. ISO 21003 applies only to multilayer pipes with their inner layer made of plastics. It covers a range of service conditions (application classes) and design pressures. It is not applicable for values of design temperature, TD, maximum design te
38、mperature, Tmax, and malfunction temperature, Tmal, in excess of those in Table 1. NOTE 1 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 installa
39、tion 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 poly(vinyl chloride) (PVC-C). The PE-X used shall be f
40、ully crosslinked and shall comply with the requirements of the relevant reference product standard (ISO 15875). NOTE 2 For the purposes of ISO 21003, crosslinked polyethylene (PE-X) as well as adhesives are considered as thermoplastic materials. Solid-wall pipes with thin outer layers (applied as pr
41、otection layers or barrier layers, for instance) are not covered by ISO 21003 but are specified in the Amendments to ISO 15874-2, ISO 15875-2 and ISO 15876-2. The total thickness of such outer layers, including the thickness of the adhesives used, shall be u 0,4 mm. BS EN ISO 21003-1:2008 Licensed C
