Vicat softening temperature or Vicat hardness is the determination of the softening point for materials that have no definite melting point, such as plastics...

The softening point is the temperature at which a material softens beyond some arbitrary softness. It can be determined, for example, by the Vicat method...

glass transition temperature of about 147 °C (297 °F), so it softens gradually above this point and flows above about 155 °C (311 °F). Tools must be held...
