適用范圍：This standard specifies a method for determining the Vicat softening temperature (VST) of pipes and fittings (see note) of thermoplastics materials, based on method B of ISO 306 : 1987, i.e. using a force of (50 ±1) N and a rate of temperature increase of 50 ℃/h. A measure of the temperature is obtainable only for those thermoplastics for which the softening becomes rapid. NOTE. The term 'fittings' is intended to also cover valves and other ancillaries made of thermoplastics material(s).
