It is specifically intended to give guidance for the assessment of confor
4、mity to BS EN 1451-1:2000 of Polypropylene (PP) piping system components and their joints. (BS EN 1451-1:2000 superseded BS 5254:1976 and partially superseded BS 5255:1989). There is no British Standard corresponding to ENV 1451-2:2001. It is available for optional use in conjunction with any other
5、existing procedures for such purposes. The UK participation in its preparation was entrusted by Technical Committee PRI/88, Plastic Piping Systems and Components to sub-committee PRI/88/1, Thermoplastic Piping Systems for non-pressure application which has the responsibility to: Aid enquiries to und

Th
29、is prestandard includes: a) requirements for materials, components, joints and assemblies given in EN 1451-1; b) requirements for the manufacturers quality system; NOTE 1 It is recommended that the quality system conforms to EN ISO 9001, as applicable. c) definitions and procedures to be applied if
30、third party certification is involved. NOTE 2 If third party certification is involved, it is recommended that the certification body is accredited to EN 45011 or EN 45012, as applicable. This Part of EN 1451 is applicable to solid-wall piping systems made of polypropylene (PP) in the field of soil
31、and waste discharge (low and high temperature) - inside buildings (application area code “B“) and - inside buildings and buried in ground within the building structure (application area code “BD“). 2 Normative references This European Prestandard incorporates by dated or undated reference, provision
