EN 1451的这一部分规定了固体聚丙烯（PP）管道，配件和系统的要求: - 建筑物内的土壤和废物排放应用（低温和高温）（应用领域代码“B”）; - 建筑物内部建筑物内的土壤和废物排放应用（低温和高温）和建筑结构内的地面（应用领域代码“BD”）。 EN 1451的这一部分也适用于PP管和配件，该系统旨在用于以下目的: - 与排放应用有关的管道通风部分; - 建筑结构内的雨水管道。 它还规定了本标准中提到的测试方法的测试参数。 该标准涵盖一系列公称尺寸，一系列管道和配件系列，并提供有关颜色的建议。 它适用于标有“B”的管道和配件，其用于建筑物内部以及固定在墙壁上的外部建筑物。 本标准适用于以下类型的PP管和配件: - 平原 - 整体弹性环密封插座; - 用于对接融合接头。 从而可以通过注射成型制造配件或者通过管道和/或模制品来制造配件

This part of EN 1451 specifies the requirements for solid-wall polypropylene (PP) pipes, fittings and the system intended for: - soil and waste discharge applications (low and high temperature) inside buildings (application area code "B"); - soil and waste discharge applications (low and high temperature) for both inside buildings and buried in the ground within the building structure (application area code "BD"). This part of EN 1451 is also applicable to PP pipes and fittings and the system intended for the following purposes: - ventilating part of the pipework in association with discharge applications; - rainwater pipework within the building structure. It also specifies the test parameters for the test methods referred to in this standard. This standard covers a range of nominal sizes, a range of pipes and fittings series and gives recommendations concerning colours. It applies to pipes and fittings, marked with "B", which are intended to be used inside buildings and outside buildings fixed onto the wall. This standard is applicable to PP pipes and fittings of the following types: - plain-ended; - with integral elastomeric ring seal socket; - for butt fusion joints. whereby the fittings can be manufactured by injection-moulding or be fabricated from pipes and/or mouldings.
