本技术规范为材料，产品，接头和组件的一致性评估提供了指导，根据EN 14758的适用部分，旨在将其作为质量管理体系的一部分纳入制造商质量计划，用于建立认证程序。 注意为了帮助读者，附件A给出了一个基本的测试矩阵。 结合EN 14758 1本文件适用于由用于（PP-MD）改性的聚丙烯制成的实心管道系统，用于: - 建筑结构外的非压力地下排水和污水处理（应用领域代码“U”）;和 - 在建筑结构内（应用领域代码“D”）和建筑结构外部埋地埋地的非压力地下排水和污水处理。 这反映在“U”和“OU”的产品标记中

This Technical Specification gives guidance for the assessment of conformity of materials, products, joints and assemblies in accordance with the applicable part(s) of EN 14758 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 In order to help the reader, a basic test matrix is given in Annex A. In conjunction with EN 14758 1 this document is applicable to solid wall piping systems made of polypropylene modified with mineral(s) (PP-MD) intended to be used for: — non-pressure underground drainage and sewerage outside the building structure (application area code “U”); and — non-pressure underground drainage and sewerage for both buried in ground within the building structure (application area code “D”) and outside the building structure. This is reflected in the marking of products by “U” and “UD”.
