4、PB) and crosslinked polyethylene (PE-X) piping systems certified to BS 7291-2 or BS 7291-3, Class S, for the following reasons.a) Attention is drawn to the statement in the Scope of this standard relating to the exclusion from it of piping systems having service conditions in excess of those quoted
5、in Table 1. Central heating systems in the UK 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 t
6、emperatures are significantly in excess of those specified in Table 1 and these UK systems are therefore not covered by this standard.1)BS 7291-1:2001, Thermoplastics pipes and associated fittings for hot and cold water for domestic purposes and heating installations in buildings Part 1: General req

It is identical with ISO 15875-1:2003, incorporating amendment 1:2007.The UK participation in its preparation was entrusted by Technical Commi

11、he normal maximum operating cold water supply pressure in the UK is 12.5 bar4)which some categories of piping systems in the BS EN ISO 15875 series of standards do not meet.2) The BS EN ISO 15875 series of standards does not specifically describe push fit joints, which are the predominant jointing m
12、ethod in the UK.3) There is a disparity between the malfunction temperature quoted in Table 1 (100 C) and the malfunction temperatures applicable to boilers (110 C) conforming to BS EN 297:19945), BS EN 483:20006)and BS EN 625:19967). Consequently piping systems could be subjected to temperatures in
13、 service for which they have not been tested.4) The unique and traditional practice 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 128288), which recommends the use of systems
14、 suitable for the maximum temperatures and pressures for their intended application specified in BS 7291-1.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 approp

EN ISO 15875-1:2003 (E)51 ScopeThis Part of EN ISO 15875 specifies the general aspects of crosslinked polyethylene (PE-X) piping systemsintended to be used for hot and cold water installations within buildings for the conveyance of water, whether or notintended for human consumption (domesti
44、c systems), and for heating systems, under design pressures andtemperatures according to the class of application (see Table 1).This standard covers a range of service conditions (application classes) and design pressure and pipe dimensionclasses. For values of TD, Tmaxand Tmalin excess of those in
