2、ents and performance characteristicsBS EN 134761:2018National forewordThis British Standard is the UK implementation of EN 134761:2018. It supersedes BS EN 134761:2007, which is withdrawn.The UK participation in its preparation was entrusted to Technical Committee PRI/88/1, Plastics piping for nonpr
3、essure applications.A list of organizations represented on this committee can be obtained on request to its secretary.The responsible UK committee gives the following advice concerning the scope and contents of EN 134761:2018. Attention is drawn to the scope of this standard, which, together with BS
4、 EN 134762:2018 and BS EN 134763:2018, is applicable to structuredwall plastic piping systems made of unplasticized poly(vinyl chloride) (PVCU), polypropylene (PP) or polyethylene (PE) with any additives needed to facilitate the manufacture of components conforming to this standard. Multilayer compo
5、site pipes with an intermediate layer of metal; reinforced pipes; and pipes made of polymers other than PVCU, PP or PE are not covered by the scope of this standard. The test methods and performance criteria are not applicable to these types of pipe. Recycled material: The use of recycled or reproce
6、ssed materials is encouraged in the UK. However, their use should be strictly in accordance with this standard. Interchangeability: This standard does not guarantee interchangeability between manufacturers. It is strongly advised that users specify the bore series of pipes (DN/ID) as specified in BS
7、 EN 134762:2018 and BS EN 134763:2018 to maximize the hydraulic performance of these products. Initial ring stiffness: The BS EN 13476 series specifies four nominal ring stiffness classes (SN): SN2, SN4, SN8 and SN16. DN 500: SN4, SN8 or SN16; DN 500: SN2, SN4, SN8 or SN16.From the viewpoint of inst
8、allation, SN4 and SN8 are the traditionally recommended classes used in the UK for water company adopted sewers and are to be used if the system is to be installed in accordance with BS EN 752:2017 or BS EN 1610:2015 to achieve the intended resistance to longterm deformation. If use of the SN2 class
9、 of pipe or fittings is intended, the installation should first be subject to a structural design soil load / traffic load calculation and the installation technique modified to suit the results of that calculation. The appropriate calculation method is given in the National Annex NA to BS EN 12951.
10、 The shortterm E modulus for the material should be taken from Table A.1 of BS EN 134761:2018. The longterm value of E should be taken as the shortterm value divided by the creep ratio. The creep ratio is derived from the tests specified in the Mechanical characteristics section of BS EN 134762:2018
11、 or BS EN 134763:2018 as appropriate. Impact: Annex G of BS EN 134762:2018 and BS EN 134763:2018 details an impact resistance test at 23C. This is the preferred test in the UK. Annex H therefore becomes informative in the UK.BRITISH STANDARDBS EN 134761:2018This publication does not purport to inclu

39、stics1 ScopeThis European Standard, together with EN 134762 and EN 134763, specifies the definitions and general requirements for pipes, fittings and the system based on unplasticized poly(vinyl chloride) (PVCU), polypropylene (PP) and polyethylene (PE) structuredwall piping systems that are to be u
40、sed for nonpressure underground drainage and sewerage systems.This standard is applicable to:a) structuredwall pipes and fittings, which are to be used buried in the ground outside a building structure only; reflected by the marking of products by “U”;b) structuredwall pipes and fittings, which are
41、to be used buried in ground both outside (application area code “U”) and within a building structure (application area code “D”); reflected in the marking of products by “UD”.In conjunction with EN 134762 and EN 134763, it is applicable to structuredwall pipes and fittings with or without an integra
42、l socket with elastomeric ring seal joints, as well as welded and fused joints.This part specifies general aspects and gives guidance concerning a national selection of requirement levels and classes where part 2 and part 3 of this standard provide options.EN 134762 and EN 134763 specify material ch
43、aracteristics, dimensions and tolerances, test methods, test parameters and requirements for pipes with smooth internal and external surfaces, Type A, and pipes with smooth internal and profiled external surfaces, Type B.This standard, together with EN 134762 and EN 134763, covers a range of pipe an
