标准范围

ISO的这一部分？22391规定了由耐高温聚乙烯（PE-RT）制成的管道的特性，该管道旨在用于建筑物内的热水和冷水装置，用于输送水——无论水是用于人类消费（家用系统）还是供暖系统——根据ISO？22391-1.它涵盖了一系列使用条件（应用类别）、设计压力和管道尺寸类别，还规定了测试参数和测试方法。当与ISO的其他部分结合使用时？22391，其分别适用于PE-RT管、配件、它们的接头，以及具有PE-RT以及其他塑料和非塑料部件的接头。塑料材料，用于热水和冷水装置。它适用于有或没有阻挡层的管道。它不适用于超过ISO规定的设计温度、最高设计温度或故障温度？22391-1.笔记？买方或指定方有责任从这些方面做出适当的选择，同时考虑其特殊要求以及任何相关的国家法规和安装惯例或规范。

This part of ISO 22391 specifies the characteristics of pipe made from polyethylene of raised temperature resistance (PE-RT), 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) or heating systems — under the design pressures and temperatures appropriate to the class of application according to ISO 22391-1.It covers a range of service conditions (classes of application), design pressures and pipe dimension classes, and also specifies test parameters and test methods. When used in conjunction with the other parts of ISO 22391, it is respectively 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, used for hot and cold water installations.It is applicable to pipes with or without a barrier layer or layers.It is not applicable for values of design temperature, maximum design temperature or malfunction temperature in excess of those specified in ISO 22391-1.NOTE          It is the responsibility of the purchaser or specifier to make the appropriate selections from these aspects, taking into account their particular requirements and any relevant national regulations and installation practices or codes.
