ISO 15875-1:2003规定了旨在用于建筑物内的热水和冷水设施的交联聚乙烯（PE-X）管道系统的一般方面，用于运输可能用于或可能不用于人类消费的水国内系统）或加热系统，在适用于应用类别的设计压力和温度下。 它涵盖一系列服务条件（应用类别），设计压力和管道尺寸等级。 它还规定了标准参考的测试方法的测试参数。 结合ISO 15875的其他部分，适用于PE-X管，配件及其接头，包括用于其他塑料部件的接头和旨在用于冷热水设备的非塑料材料

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.
