ISO 15874-5:2013规定了聚丙烯（PP）管道系统的适用性特征，该管道系统拟用于建筑物内输送水的热水和冷水装置，无论是否用于人类消费（家用系统）和供暖系统，其设计压力和温度取决于应用类别。 它涵盖了一系列工作条件（应用等级）和设计压力等级。 它还规定了测试方法的测试参数。 与ISO 15874的其他部分一起，它适用于PP管、管件及其接头，以及与其他塑料和非金属部件的接头- 用于热水和冷水装置的塑料材料。

ISO 15874-5:2013 specifies the characteristics of the fitness for purpose of polypropylene (PP) piping systems, intended to be used for hot and cold water installations within buildings for the conveyance of water, whether or not intended for human consumption (domestic systems) and for heating systems, under design pressures and temperatures according to the class of application. It covers a range of service conditions (classes of application) and design pressure classes. It also specifies test parameters for test methods. In conjunction with the other parts of ISO 15874, it is applicable to PP pipes, fittings, their joints and to joints with components of other plastics and non-plastics materials intended to be used for hot and cold water installations.
