ISO 15875-1:2003规定了交联聚乙烯（PE-X）管道系统的一般方面，该系统拟用于建筑物内的热水和冷水装置，用于输送可能用于或可能不用于人类消费（家用系统）的水，或用于加热系统，其设计压力和温度与应用类别相适应。 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。 它还规定了本标准中提及的试验方法的试验参数。 与ISO 15875的其他部分一起，它适用于PE-X管道、配件及其接头，包括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 15875-1:2003 specifies the general aspects of crosslinked polyethylene (PE-X) 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 design pressures and temperatures appropriate to the class of application. It covers a range of service conditions (classes of application), design pressures and pipe dimension classes. 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, fittings and their joints, including joints with components of other plastics and non-plastics materials intended to be used for hot and cold water installations.
