ISO 15877-1:2009规定了在适用于应用类别的设计压力和温度下，用于建筑物内冷水和热水输送的氯化聚氯乙烯（PVC-C）管道系统的一般要求，无论是否用于人类消费（家用系统）和供暖系统。 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。如果设计温度、最高设计温度和故障温度的值超过给定值，则不适用。 ISO 15877-1:2009还规定了其所指试验方法的试验参数。 与ISO 15877的其他部分一起，它适用于PVC-C管道和配件、其接头以及与其他塑料和非塑料材料部件的接头，用于热水和冷水装置。

ISO 15877-1:2009 specifies the general requirements of chlorinated poly(vinyl chloride) (PVC-C) 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 appropriate to the class of application. It covers a range of service conditions (classes of application), 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. ISO 15877-1:2009 also specifies the test parameters for the test methods to which it refers. In conjunction with the other parts of ISO 15877, it is applicable to PVC-C pipes and fittings, their joints and joints with components of other plastics and non-plastics materials intended to be used for hot and cold water installations.
