标准范围

本文件规定了一种测定热塑性塑料管道纵向反转的方法，该方法在液体或空气中进行。如有争议，以加热液体为参考。本文件适用于所有具有恒定交叉的光滑内壁和外壁的热塑性塑料管道？部分。它不适用于非？结构流畅？壁式热塑性塑料管道。附件中给出了适用于管道材料的参数和作为管道材料函数的最大回复水平的建议？A.本方法适用于壁厚≤16？嗯。

This document specifies a method for determining the longitudinal reversion of thermoplastics pipes, to be carried out in either a liquid or in air. In case of dispute, heated liquid is used as the reference.

This document is applicable to all thermoplastics pipes with smooth internal and external walls of constant cross？section. It is not applicable to non？smooth structured？wall thermoplastics pipes.

The parameters appropriate to the pipe material and recommendations for the maximum levels of reversion as a function of the pipe material are given in Annex A.

This method is applicable for pipes of wall thickness ≤ 16 mm.
