This depends on application. Definitions: Vicat softening point.Vicat softening temperature or Vicat hardness is the determination of the softening point for materials that have no definite melting point, such as plastics. It is taken as the temperature at which the specimen is penetrated to a depth of 1 mm by a flat-ended needle with a 1 mm² circular or square cross .The heat distortion temperature test is determined by the following test procedure outlined in ASTM D648. The test specimen is loaded in three-point bending in the edgewise direction.

The Heat Deflection Temperature (HDT), or Heat Distortion Temperature, is a measure of a polymer’s resistance to alteration under a given load at an elevated temperature. It is also known as the ‘deflection temperature under load’ (DTUL) or ‘heat deflection temperature under load (HDTUL)’.Traditional HDT Vicat test methods use silicon oil as the heating medium, but silicon oil has a high-temperature limit of 300°C. This temperature is not high enough to test new families of materials known as techno-polymers, which have HDT values of up to 500°C. Aluminum oxide is an alternative heating medium for high-temperature applications.

This can be divided into Vicat softening temperature and HDT (heat deflection temperature). In both methods an oil-bath is heated at a defined rate and the temperature is recorded at a deflection or indentation depth specified by the standard. Vicat softening temperature to ISO 306 and ASTM D1525 (VST: Vicat softening temperature) Vicat .The heat distortion temperature is the temperature at which a piece of PVC, placed in the heat medium with a bending load applied onto it, reaches a specified deflection as temperature rises. The Vicat softening temperature is defined as the temperature where the needle shaped penetrator sinks into the test piece to a specified depth.
