EN 727:1994
(Main)Plastics piping and ducting systems - Thermoplastics pipes and fittings - Determination of Vicat softening temperature (VST)
General Information
- Abstract
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°C/h. A measure of the temperature is obtainable only for those thermoplastics for which the softening becomes rapid.
