冷热水装置用塑料管道系统.耐升温的聚乙烯(PE-RT).第5部分:系统的适用性

[中文适用范围]： 本部分ISO 22391规定了由耐热聚乙烯（PE-RT）I型和II型制成的管道系统的适用性特征，该系统用于建筑物内的热水和冷水安装，用于输送水（无论是否用于人类消费，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PE-RT管道、管件、其接头，以及由PE-RT以及其他塑料和非塑料材料组成的接头，用于热水和冷水安装。它不适用于超过ISO 22391-1中规定的最高设计温度、最大设计温度或故障温度的值。注：选择这些方面的责任在于采购方或规范制定方，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 22391-5:2009 specifies the characteristics of the fitness for purpose 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 the design pressures and temperatures appropriate to the class of application according to ISO 22391-1. ISO 22391-5:2009 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 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.
