该欧洲标准与EN 13476 2和EN 13476 3一起规定了基于未增塑的聚氯乙烯（PVC-U），聚丙烯（PP）和聚乙烯（PE）的管道，配件和系统的定义和一般要求，用于非压力地下排水和污水处理系统的结构化壁管系统。 本标准适用于: a）仅用于建筑结构外的埋设在地下的结构化壁管和配件;反映在产品的标记“— b）结构化壁管和配件，要被埋在地面以外（应用领域代码“U”）和建筑结构（应用领域代码“D”）;反映在产品的标记“— 结合EN 13476 2和EN 13476 3，它适用于具有或不具有弹性体环密封接头的整体插座以及焊接和熔合接头的结构化壁管和配件。 本部分规定了一般方面，并提出了关于国家对本标准第2部分和第3部分提供选择的要求等级和类别选择的指导意见。 EN 13476 2和EN 13476 3指定材料特性，尺寸和公差，测试方法，测试参数和p的要求

This European Standard, together with EN 13476 2 and EN 13476 3, specifies the definitions and general requirements for pipes, fittings and the system based on unplasticized poly(vinyl chloride) (PVC-U), polypropylene (PP) and polyethylene (PE) structured-wall piping systems that are to be used for non-pressure underground drainage and sewerage systems. This standard is applicable to: a) structured-wall 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) structured-wall pipes and fittings, which are 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 13476 2 and EN 13476 3, it is applicable to structured-wall pipes and fittings with or without an integral 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 13476 2 and EN 13476 3 specify material characteristics, 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 13476 2 and EN 13476 3, covers a range of pipe and fitting sizes, materials, pipe constructions, stiffness classes and tolerance classes and offers recommendations concerning colours. NOTE 1 It is the responsibility of the purchaser or specifier to make the appropriate selections from these aspects, taking into account their particular requirements and any relevant national regulations and installation practices or codes. NOTE 2 Pipes, fittings and other components conforming to any plastic product standards referred to in Clause 2 can be used with pipes and fittings conforming to this standard, when they conform to the requirements for joint dimensions given in part 2 and part 3 of this standard and to the performance requirements given in Clause 9.
