标准摘要
[中文适用范围]: 本文件规定了根据相关 ISO 标准规定的聚乙烯 (PE) 管道系统组件对接熔接接头的施工和质量评估程序的一般原则。 这些组件是根据相关实践规范、国家法规或行业指南安装的。 具体来说,本文件规定了 PE 管道和配件的三种对接熔接程序。 它们是: ——单一低压熔接工艺; ——双低压熔接工艺; ——单次高压熔接工艺。 本文件考虑了所使用的材料和部件、熔接程序和设备以及已完成接头的质量评估。 它可以与相应的国家法规和标准结合应用。 注 1:这些程序的参考文献在参考书目中给出。 [1][2][3][4][5][6]单一低压熔接工艺是由多个工艺衍生而来并得到专家一致同意的,在参考文献中给出[1][2]。 注 2:本文件中详述的三个程序基于最常用的程序。 无意使用这些程序中的一个或多个来取代完善且经过验证的基于行业的程序。 [外文原描述]: ISO 21307:2017 establishes general principles regarding the procedure used in the construction and quality assessment of butt fusion jointing of polyethylene (PE) piping system components specified in accordance with relevant ISO standards. These components are installed in accordance with the relevant codes of practice, national regulations or industry guidance. Specifically, this document specifies three butt fusion jointing procedures for PE pipes and fittings. These are: - single low-pressure fusion jointing procedure; - dual low-pressure fusion jointing procedure; - single high-pressure fusion jointing procedure. ISO 21307:2017 takes into consideration the materials and components used, the fusion jointing procedure and equipment and the quality assessment of the completed joint. It can be applied in conjunction with appropriate national regulations and standards.
