本文件为根据EN 13476适用部分对材料、产品、接头和组件的符合性进行评估提供了指导，该部分将作为质量管理体系的一部分纳入制造商的质量计划，并用于建立认证程序。注1:质量管理体系应符合或不低于EN ISO 9001[1]的相关要求。注2:如果涉及第三方认证，认证机构可获得EN ISO\/IEC 17065[2]或EN ISO\/IEC 17021[3]认证（如适用）。注3:为了帮助读者，附录a中给出了基本测试矩阵。结合EN 13476 1、EN 13476 2和EN 13476 3，本文件适用于无压力地下排水和污水处理用塑料管道系统-未增塑聚氯乙烯（PVC-U）、聚丙烯（PP）和聚乙烯（PE）结构墙管道系统:-建筑结构外的无压地下排水和污水（应用区域代码“U”）用“U”表示，并-对于建筑结构内（应用区域代码“D”和建筑结构外（应用区域代码“U”）地下埋置的无压地下排水和污水，用“UD”标记产品。

This document gives guidance for the assessment of conformity of materials, products, joints and assemblies in accordance with the applicable part(s) of EN 13476 intended to be included in the manufacturer’s quality plan as part of the quality management system and for the establishment of certification procedures. NOTE 1 The quality management system is expected to conform to or be no less stringent than the relevant requirements to EN ISO 9001 [1]. NOTE 2 If third-party certification is involved, the certification body can be accredited to EN ISO/IEC 17065 [2] or EN ISO/IEC 17021 [3], as applicable. NOTE 3 In order to help the reader, a basic test matrix is given in Annex A. In conjunction with EN 13476 1, EN 13476 2 and EN 13476 3 this document is applicable to Plastics piping systems for non-pressure underground drainage and sewerage — Structural-wall piping systems of unplasticized poly(vinyl chloride) (PVC-U), polypropylene (PP) and polyethylene (PE): - for non-pressure underground drainage and sewerage outside the building structure (application area code “U”) reflected in the marking of products by “U”, and - for non-pressure underground drainage and sewerage for both buried in ground within the building structure (application area code “D” and outside the building structure (application area code “U”) reflected in the marking of products by “UD”.
