标准摘要
[中文适用范围]: 本ISO 22391-3部分规定了由以下材料制成的管道系统配件的特性: - 耐温聚乙烯(PE-RT),I型; - 耐温聚乙烯(PE-RT),II型。 这些配件旨在用于建筑物内的热水和冷水安装系统,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,其设计压力和温度应符合ISO 22391-1中规定的适用应用类别。 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测试方法。结合ISO 22391的其他部分,它适用于由PE-RT制成的配件,以及由其他材料制成的配件,这些配件旨在安装在符合ISO 22391-2的管道上,用于热水和冷水安装,其接头符合ISO 22391-5。 本部分适用于以下类型的配件: - 机械配件; - 承插热熔配件; - 电熔配件; - 带内置插头的配件。 它不适用于设计温度、最高设计温度或故障温度超过ISO 22391-1中规定值的配件。 注:选择适当的方面是采购方或指定方的责任,需考虑其特定要求以及任何相关的国家法规和安装实践或规范。 [外文原描述]: ISO 22391-3:2009 specifies the characteristics of fittings for 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 the design pressures and temperatures appropriate to the class of application according to ISO 22391-1. ISO 22391-3:2009 covers a range of service conditions (classes of application), design pressures and pipe dimension classes, and also specifies test parameters and test methods. In conjunction with the other parts of ISO 22391, it is applicable to fittings made of PE-RT, as well as to those made of other materials, intended to be fitted to pipes conforming to ISO 22391-2 for hot and cold water installations, the joints of which are in accordance with ISO 22391-5. It is applicable to the following types of fitting: - mechanical fittings; - socket fusion fitting; - electrofusion fittings; - fittings with incorporated inserts.
