It is identical with ISO 15874-1:2003. The UK participation in its prepar

5、BS 7291-2 or BS 7291-3, Class S, for the following reasons. a) Attention is drawn to the statement in the Scope of BS EN ISO 15874-1 relating to the exclusion from it of piping systems having service conditions in excess of those quoted in BS EN ISO 15874-1, Table 1. Central heating systems in the U

6、K fall into this category. BS 7291-1 states the service conditions for UK systems where the maximum system service temperature for sealed central heating systems, designated as Class S, is 105 C and the system malfunction temperature is 114 C. Both these temperatures are significantly in excess of t

20、piping systems in the BS EN ISO 15874 series of standards do not meet. 2) The BS EN ISO 15874 series of standards does not specifically describe push fit joints, which are the predominant jointing method in the UK. 3) There is a disparity between the malfunction temperature quoted in BS EN ISO 15874

21、-1, Table 1 (100 C) and the malfunction temperatures applicable to boilers (110 C) conforming to BS EN 297:1994 5) , BS EN 483:2000 6)and BS EN 625:1996 7) . Consequently piping systems could be subjected to temperatures in service for which they have not been tested. 4) The unique and traditional p
