    Abstract - (Show below) - (Hide below)

    Defines a method for determining the longitudinal reversion of thermoplastics pipes, to be carried out in either a liquid or in air.

    Scope - (Show below) - (Hide below)

    This International Standard 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 International Standard 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 AnnexA.

    NOTE Measurement of longitudinal reversion is not considered relevant for pipe wall thickness greater than 16mm.
