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
22、ractice in the UK is to use products certified to BS 7291-2 or BS 7291-3, Class S, for all applications, as defined in BS 7291-1. This is recognized in the national annex to BS EN 12828 8) , which recommends the use of systems suitable for the maximum temperatures and pressures for their intended ap

Updated versions of BS 7291-1, BS 7291-2 and BS 7291-3 are being prepared, which maintain these traditional UK operating conditions, and measures are being taken to address this issue in appropriate harmonized European Standards.
