标准摘要
[中文适用范围]: 本部分ISO 22391规定了由以下材料制成的管道系统的通用特性: - 耐热聚乙烯(PE-RT),I型; - 耐热聚乙烯(PE-RT),II型。 这些系统旨在用于建筑物内的热水和冷水安装,用于输送水(无论是否供人类饮用,即家庭系统)以及供暖系统,并在适用于应用类别的指定设计压力和温度下运行。 本部分涵盖了各种服务条件(应用类别)、设计压力和管道尺寸类别,并规定了测试参数和定义了术语。结合ISO 22391的其他部分,它适用于用于热水和冷水安装的PE-RT管道、管件、其接头以及具有PE-RT部件的接头,以及其他塑料和非塑料材料。 它不适用于超过其规定值的设计温度、最高设计温度或故障温度。 注:采购方或指定方有责任根据特定要求以及任何相关国家法规和安装实践或规范,从这些方面做出适当的选择。 [外文原描述]: ISO 22391-1:2009 specifies the general characteristics of piping systems made of polyethylene of raised temperature resistance (PE‑RT), Type I and polyethylene of raised temperature resistance (PE-RT), Type II intended to be used for hot and cold water installations within buildings for the conveyance of water, whether or not the water is intended for human consumption (domestic systems) and for heating systems, under specified design pressures and temperatures appropriate to the class of application. ISO 22391-1:2009 covers a range of service conditions (classes of application), design pressures and pipe dimension classes, and also specifies test parameters and defines terms. In conjunction with the other parts of ISO 22391, it is applicable to PE-RT pipes, fittings, their joints and to joints having components of PE-RT, as well as of other plastics and non-plastics materials, respectively, used for hot and cold water installations.
