标准摘要
[中文适用范围]： 本文件规定了用于埋地和用于供应气体燃料的未塑化聚酰胺（PA-U）管道系统的适用性要求。 它还规定了电熔接头和对接熔接头的定义。 本文件规定了试件接头的制备方法以及对这些接头进行的测试，以评估系统在正常和极端条件下的适用性。 它还指定了它所引用的测试方法的测试参数。 熔接和/或机械连接。 与 ISO 16486 的其他部分一起，它适用于 PA-U 配件、其接头以及带有 PA-U 组件的接头。 [外文原描述]： This document specifies the requirements of fitness for purpose of unplasticized polyamide (PA-U) piping system, intended to be buried and used for the supply of gaseous fuels. It also specifies the definitions of electrofusion and butt fusion joints. This document specifies the method of preparation of test piece joints and the tests to be carried out on these joints for assessing the fitness for purpose of the system under normal and extreme conditions. It also specifies the test parameters for the test methods to which it refers. The ISO 16486 series is applicable to PA-U piping systems, the components of which are connected by fusion jointing and/or mechanical jointing. In conjunction with the other parts of ISO 16486, it is applicable to PA-U fittings, their joints and to joints with components of PA-U.
