3、 ISO 21003-3:2008.The UK participation in its preparation was entrusted by Technical Committee PRI/88, Plastics piping systems, to Subcommittee PRI/88/2, Plastic piping for pressure applications.The UK Committee would like to emphasise that compliance with this British Standard does not necessarily
4、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 the U
5、K. In particular: (i) The normal maximum operating cold water supply 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
6、 defines mechanical fittings in general. (iii) There is a disparity 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 prac
7、tice can be found in BS 7291-1 which should be consulted when applying 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
8、 Class S for all applications, as defined in BS 7291-1. This is recognized 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. This standard does not replace BS 7291 Parts 1,
9、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. Amendments/corrigenda issued since publicationDate CommentsBS EN ISO 21003-3:2008iIn addition to the above, pipes con
10、forming to this standard may also be required to convey water intended for human consumption. The legislation setting out the requirements for water supply installations in the UK is as follows: the Water Supply (Water Quality) Regulations 2000, Regulation 31 (England); the Water Supply (Water Quali
11、ty) Regulations 2001, Regulation 31 (Wales); the Water Supply (Water Quality) Regulations 2001, Regulation 27 (Scotland); the Water Supply (Water Quality) Regulations 2007, Regulation 30 (Northern Ireland) for installations for public water supplies; the Water Supply (Water Fittings) Regulations 199
12、9 (England and Wales); the Water Byelaws 2000 (Scotland); and the current requirements for Northern Ireland for installations for consumers premises.

30、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 potentially adverse effects on the quality of water intended for human consumption caused by the products covered by ISO 21003: no informati
31、on 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 verifiable European criteria, existing national regulations concerning the use and/or the characteristics of these products
32、 remain in force. Requirements and test methods for materials and components other than fittings are specified in ISO 21003-1 and ISO 21003-2. Characteristics for fitness for purpose (mainly for joints) are covered in ISO 21003-5. ISO/TS 21003-7 gives guidance on the assessment of conformity. This p
33、art of ISO 21003 specifies the characteristics of fittings. 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 21003-3:20081Multilayer piping systems for hot
34、 and cold water installations inside buildings Part 3: Fittings 1 Scope This part of ISO 21003 specifies the characteristics of fittings for multilayer piping systems intended to be used for hot and cold water installations inside buildings for the conveyance of water whether or not the water is int
35、ended for human consumption (domestic systems) or for heating systems under specified design pressures and temperatures appropriate to the class of application (see Table 1 of ISO 21003-1:2008). It also specifies the test parameters for the test methods referred to in this part of ISO 21003. ISO 210
36、03 is a reference product standard. 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 only in conjunct
37、ion with all the other parts of ISO 21003. This part of ISO 21003 covers fusion, solvent-cemented and mechanical fittings for a range of service conditions (application classes) and design pressures. It is not applicable for values of design temperature, TD, maximum design temperature, Tmax, and mal
38、function temperature, Tmal, in excess of those in Table 1 of ISO 21003-1:2008. 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 installation
39、 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 fully
40、 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. 2 Normative references The following referenced documents
