2、al forewordThis Draft for Development is the UK implementation of CEN ISO/TS 21003-7:2008+A1:2010. It is identical to ISO/TS 21003-7:2008, incorporating amendment 1:2010. It supersedes DD CEN ISO/TS 21003-7:2008 which is withdrawn.The start and finish of text introduced or altered by amendment is in

For example, text altered by ISO amendment A1 is indicated by !“.The UK Committee would like to emphasise that compliance with this Draft for Development does not necessarily mean that products ar

In particular: (i) T
5、he normal maximum operating cold water supply pressure in the UK is 12.5 bar, a pressure that some application classes of pipe in this Draft for Development do not meet.(ii) This Draft for Development does not specifically describe push-fit joints that are the predominant jointing method in the UK b
6、ut 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 Draft for Development and the malfunction temperatures applicable to boilers (110 C) conforming to BS EN 297:1994, BS EN 483:2000 and BS EN 625:1996. C
7、urrent UK practice can be found in BS 7291-1 which should be consulted when applying this Draft for Development. 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 pro
8、ducts 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 Draft for Developm
9、ent 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.This publication is not to be regarded as a British Standard.DD CEN ISO/TS 21003
