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

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

(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.
