3、e UK implementation of EN ISO 21003-5:2008. 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 Sta

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 pi
5、pework application in the UK. 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 jo
6、inting method in the UK but 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 E
7、N 625:1996. Current UK practice 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 pr
8、oducts certified to BS 7291 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 no

The multilayer piping system is intended to be used for hot and cold water installations inside buildings. In respect of potential adver
28、se effects 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
29、verifiable 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 21003-1, ISO 21003-2 and ISO 21003-3. ISO/TS 21003-7 gives guidance on t
30、he assessment of conformity. This part of ISO 21003 specifies the characteristics for fitness for purpose. For ancillary equipment, separate standards can apply.

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
35、ion with all the other parts of ISO 21003. ISO 21003 covers 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 malfunction temperature, Tmal, in excess of those in Table 1 of ISO 2
