ISO 15877-5:2009规定了氯化聚氯乙烯（PVC-C）管道系统的适用性特征，该系统拟用于建筑物内的热水和冷水装置，以输送水，无论是否用于人类消费，（家用系统）以及供暖系统，根据应用类别，在设计压力和温度下。 ISO 15877-5:2009涵盖了一系列工作条件（应用等级）和设计压力等级。如果设计温度、最高设计温度和故障温度的值超过ISO 15877-1:2009中给出的值，则不适用。ISO 15877-5:2009规定了相关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金属部件的接头- 用于热水和冷水装置的塑料材料。

ISO 15877-5:2009 specifies the characteristics of the fitness for purpose 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 according to the class of application. ISO 15877-5:2009 covers a range of service conditions (application classes) and design pressure 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 15877-1:2009. ISO 15877-5:2009 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.
