ISO 15875-2:2003规定了用于管道系统的交联聚乙烯（PE-X）的管道系统的特性，用于在建筑物内的热水和冷水设施，用于运输水，可能用于或不用于人类消费（家庭系统）或供暖系统，在适用于应用类别的经营压力和温度下。 它涵盖一系列服务条件（应用类），设计压力和管道维度等级。如果设计温度，最大设计温度和故障温度的值超过ISO 15875-1中给出的值，则不适用。 它还规定了标准参考的测试方法的测试参数。 与ISO 15875的其他部分结合使用，适用于PE-X管及其接头，包括与其他PE-X部件的接头和由其他塑料制成的部件和旨在用于冷热水的非塑料材料安装。 适用于具有或不具有（a）阻挡层的管道

ISO 15875-2:2003 specifies the characteristics of pipes made from crosslinked polyethylene (PE-X) for piping systems intended to be used for hot and cold water installations, within buildings, for the conveyance of water which may or may not be intended for human consumption (domestic systems) or for heating systems, under operating pressures and temperatures appropriate to the class of application. It covers a range of service conditions (application classes), design pressures and pipe dimension classes. It does not apply if the values of the design temperature, maximum design temperature and malfunction temperature are in excess of those given in ISO 15875-1. It also specifies the test parameters for the test methods referred to in the standard. In conjunction with the other parts of ISO 15875, it is applicable to PE-X pipes and their joints, including joints with other PE-X components and components made of other plastics and non-plastics materials intended to be used for hot and cold water installations. It is applicable to pipes with or without (a) barrier layer(s).
