5、of BS EN ISO 15875-1 relating to the exclusion from it of piping systems having service conditions in excess of those quoted in BS EN ISO 15875-1, 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 servi

6、ce 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 those specified in BS EN ISO 15875-1, Table 1 and these UK systems are therefore not covered by this standard.1)B

10、ntical with ISO 15875-2:2003, incorporating amendment 1:2007.The UK participation in its preparation was entrusted by Technical Committee PRI/88, Plastics piping systems, to Subcommittee PRI/88/2, Plastics piping systems for pressure applications.BS EN ISO 15875-2:2003 BSI 2007b) In addition to the

11、above:1) The 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

12、jointing method in the UK.3) There is a disparity between the malfunction temperature quoted in BS EN ISO 15875-1, 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

13、 subjected to temperatures in 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

14、recommends the use of systems 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

EN ISO 15875-2:2003 (E)51 ScopeThis Part of EN ISO 15875 specifies the characteristics of pipes made from crosslinked polyethylene (PE-X) forpiping systems intended to be used for hot and cold water installations within buildings for the conveyance of water,whether or

45、 not intended for human consumption (domestic systems), and for heating systems, under designpressures and temperatures appropriate to the class of application (see Table 1 of EN ISO 15875-1:2003).This standard covers a range of service conditions, (application classes), design pressures and pipe di

46、mensionclasses. For values of TD, Tmax and Tmal in excess of those in Table 1of Part 1, this standard does not apply.NOTE 1 It is the responsibility of the purchaser or specifier to make the appropriate selections from these aspects, taking into account theirparticular requirements and any relevant

47、national regulations and installation practices or codes.It also specifies the test parameters for the test methods referred to in this standard.In conjunction with the other Parts of EN ISO 15875 (see Foreword) it is applicable to PE-X pipes, their joints andto joints with components of PE-X, other

48、 plastics and non-plastics materials intended to be used for hot and coldwater installations.It is applicable to pipes with or without (a) barrier layer(s).NOTE 2 In the case of plastics pipes provided with a thin barrier layer, e.g. to prevent or greatly diminish the diffusion of gases and thetrans

49、mission of light into or through the pipe wall, the design stress requirements are totally met by the base polymer (PE-X).2 Normative referencesThis Standard incorporates by dated or undated reference, provisions from other publications. These normativereferences are cited at the appropriate places in the text and the publications are listed hereafter.
