ISO 15877-2:2009规定了由氯化聚氯乙烯（PVC-C）制成的管道系统的要求，该管道系统拟用于建筑物内的热水和冷水输送装置，无论是否拟用于人类消费（家用系统）和供暖系统，其设计压力和温度与应用类别相适应。 ISO 15877-2:2009涵盖了一系列工作条件（应用等级）、设计压力和管道系列。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 15877-2:2009还规定了其所指试验方法的试验参数。 与ISO 15877的其他部分一起适用于PVC- C管道、其接头以及与PVC-C组件、其他塑料和非塑料材料的接头，拟用于热水和冷水装置。

ISO 15877-2:2009 specifies the requirements of pipes made from chlorinated poly(vinyl chloride) (PVC-C) for 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. ISO 15877-2:2009 covers a range of service conditions (application classes), design pressures and pipe series. 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 15877-2:2009 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, their joints and joints with components of PVC-C, other plastics and non-plastics materials intended to be used for hot and cold water installations.
