Thermoplastics pipes — Longitudinal reversion — Test method and parameters
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.
