本文件规定了由聚乙烯（PE）管或套管端配件和电熔配件（例如，连接器或鞍座等承插配件）组装的试件的制备方法。 规定的装配标准包括环境温度、熔合条件、管件和管道尺寸、管道配置（盘管或直管）等参数，同时考虑到相关产品标准规定的极限使用条件。 根据制造商的说明，本文件可适用于其他形状，例如重新倒圆的管道。 注:就本文件而言，PE被理解为PE、PE-RT或PE-X。

This document specifies a method for the preparation of test pieces assembled from polyethylene (PE) pipes or spigot-ended fittings and electrofusion fittings (e.g. socket fittings such as couplers, or saddles). The assembly criteria specified include parameters such as ambient temperature, fusion conditions, fitting and pipe dimensions, pipe configuration (coiled or straight pipe), taking into account the limiting service conditions specified by the relevant product standards. This document can apply to other shapes, e.g. re-rounded pipes, dependent on the manufacturer's instructions. NOTE For the purpose of this document, PE is understood to be PE, PE-RT or PE-X.
