THERMOPLASTICS PIPES – LONGITUDINAL REVERSION – PART 1 : DETERMINATION METHODS (ISO 2505-1:1994, IDT)
This Malaysian Standard specifies two methods for determining the longitudinal reversion of thermoplastics pipes, to be carried out in liquid (method A) or in air (method B). In case of disagreement, method A is to be used as the reference method. It applies to all thermoplastics pipes with smooth internal and external walls of constant cross-section. lt does not apply to non-smooth structured-wall thermoplastics pipes (ringed, for instance).
