冷热水装置用塑料管道系统.氯化聚氯乙烯(PVC-C).第3部分:配件

[中文适用范围]： 本部分 ISO 15877 规定了用于建筑物内热水和冷水安装系统（无论是否供人类饮用，即家庭系统）以及根据应用类别（见 ISO 15877-1:2009 表 1）的设计压力和温度的供暖系统管道系统的氯化聚氯乙烯（PVC-C）接头的特性。本部分 ISO 15877 涵盖了一系列服务条件（应用类别）和设计压力类别。对于超过 ISO 15877-1:2009 表 1 中 TD、Tmax 和 Tmal 值的范围，本部分 ISO 15877 不适用。注 1：选择者或规范制定者有责任根据具体情况、相关国家法规和安装实践或规范，从这些方面做出适当选择。它还规定了本部分 ISO 15877 中提及的测试方法的参数。结合 ISO 15877 的其他部分，它适用于 PVC-C 接头、其接头以及用于热水和冷水安装的 PVC-C 接头与其他塑料和非塑料材料组件的接头。本部分 ISO 15877 适用于以下类型的接头：溶剂胶接接头；机械接头；带内置插头的接头。注 2：PVC-C 接头是通过注塑成型的。 [外文原描述]： ISO 15877-3:2009 specifies the characteristics of fittings 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 according to the class of application. ISO 15877-3:2009 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 15877-3:2009 also specifies the parameters for the test methods to which it refers. In conjunction with the other parts of ISO 15877, it is applicable to PVC-C fittings, 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. It is applicable to fittings of the following types: fittings for solvent cement joints; mechanical fittings; fittings with incorporated inserts.
