ISO 15874-1:2013规定了聚丙烯（PP）管道系统的一般方面，该系统拟用于建筑物内的冷热水装置，用于输送水，无论是否供人类使用（家用系统），以及用于供暖系统，其设计压力和温度根据应用类别而定。 它涵盖了一系列工作条件（应用类别）、设计压力和管道尺寸类别。 它还规定了测试方法的测试参数。 ISO 15874-1:2013与ISO 15874的其他部分一起适用于PP管道、配件及其接头，以及与其他塑料和非塑料材料组成的用于热水和冷水装置的接头。

ISO 15874-1:2013 specifies the general aspects 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), design pressures and pipe dimension classes. It also specifies test parameters for test methods. In conjunction with the other parts of ISO 15874, ISO 15874-1:2013 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.
