标准摘要
[中文适用范围]： 该文件根据ISO 16486-1规定了未增塑聚酰胺（PA-U）管材的物理和机械性能，适用于要埋设并用于气体燃料供应的管材。此外还指定了所引用测试方法的试验参数。ISO 16486系列适用于通过熔接和/或机械连接方式连接的PA-U管道系统。特别是，该文件规定了管材的尺寸特性和标记要求。符合本文件规定的管材通常使用机械、电熔或对接技术进行连接。 [外文原描述]： This document specifies the physical and mechanical properties of pipes made from unplasticized polyamide (PA-U) in accordance with ISO 16486-1, intended to be buried and used for the supply of gaseous fuels. 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 particular, this document lays down dimensional characteristics and requirements for the marking of pipes. Pipes conforming to this document are jointed typically by using mechanical, electrofusion or butt fusion techniques.
