ISO 15877-5:2009规定了用于氯化聚氯乙烯（PVC-C）管道系统适用性的特性，旨在用于建筑物内用于运输水的冷热水设施，无论是否根据应用类别，设计压力和温度，用于人类消费（家庭系统）和供暖系统。 ISO 15877-5:2009涵盖了一系列服务条件（应用类）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指定了其参考的测试方法的测试参数。 与ISO 15877的其他部分相结合，适用于PVC-C管和配件，其接头和接头，其他塑料和非塑料材料的部件用于冷热水设施

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.
