本技术规范为符合EN 1565标准的材料（化合物/制剂），产品和组件的一致性评估提供了指导意图，作为质量管理体系的一部分，以及制造商质量计划的一部分的第三方认证程序。 注1:建议质量管理体系符合EN ISO 9001 [1]的相关要求或严格要求。 注2:如果涉及第三方认证，建议认证机构根据EN 45011 [2]，EN 45012 [3]或EN ISO/IEC 17021 [4]的认证。 注3:为了帮助读者，附件A给出了基本的测试矩阵。 结合EN 1565 1，本文件适用于旨在用于以下目的的苯乙烯共聚物共混物（SAN PVC）制成的固体壁管道系统: - 建筑物内的土壤和废物排放（低温和高温）（应用领域代码“B”）; - 用于建筑物内部建筑物内的土壤和废物排放（低温和高温），并埋在建筑结构内的地面（应用领域代码“BD”）。 注4:这反映在“B”或“BD”的产品标记中

This Technical Specification gives guidance for the assessment of conformity of materials (compounds/formulations), products and assemblies in accordance with EN 1565 1 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 It is recommended that the quality management system conforms to or is no less stringent than the relevant requirements of EN ISO 9001 [1]. NOTE 2 If third-party certification is involved, it is recommended that the certification body is accredited to EN 45011 [2], EN 45012 [3] or EN ISO/IEC 17021 [4], as applicable. NOTE 3 In order to help the reader, a basic test matrix is given in Annex A. In conjunction with EN 1565 1, this document is applicable to solid-wall piping systems made of styrene copolymer blends (SAN+PVC) intended to be used for the following purposes: - for soil and waste discharge (low and high temperature) inside buildings (application area code "B"); - for soil and waste discharge (low and high temperature) for both inside buildings and buried in ground within the building structure (application area code "BD"). NOTE 4 This is reflected in the marking of products by "B" or "BD".
