本文件为根据EN 1451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，并为建立第三方认证程序提供了指导。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，认证机构应获得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中给出了试验制度的概要。结合EN 1451 1，本文件适用于拟使用聚丙烯（PP）制成的管道系统:-建筑物内的土壤和废物排放系统（低温和高温）（应用区域代码“B”）和，-用于建筑物内部和建筑物内地下的土壤和废物排放系统（低温和高温）（应用区域代码“BD”）这反映在产品的“B”或“BD”标记上。

This document gives guidance for the assessment of conformity of materials, products, joints and assemblies in accordance with the applicable part(s) of EN 1451 intended to be included in the manufacturer’s quality plan as part of the quality management system and for the establishment of third-party certification procedures. NOTE 1 The quality management system is expected to conform to or is no less stringent than the relevant requirements to EN ISO 9001 [1]. NOTE 2 If third-party certification is involved, the certification body is expected be accredited to EN ISO/IEC 17065 [2] or EN ISO/IEC 17021 [3], as applicable. NOTE 3 In order to help the readers, a summary of the test regime is given in Annex A. In conjunction with EN 1451 1 this document is applicable to piping systems made of polypropylene (PP) intended to be used: - for soil and waste discharge systems (low and high temperature) inside buildings (application area code “B”) and, - for soil and waste discharge systems (low and high temperature) for both inside buildings and buried in ground within the building structure (application area code “BD”) This is reflected in the marking of products by “B” or “BD”.
