Thermoplastics pipes. Longitudinal reversion. Test methods and parameters included-in-kit — nominal values and tolerances1 Scope 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
