VST HDT (Vicat Softening Temperature)

VST HDT (Vicat Softening Temperature)

The Vicat softening temperature is used in measuring technology for the melting point. It indicates the temperature at which a circular indenter with a cross-section of 1 mm² under a standard load of 10 N or 50 N will penetrate the specimen precisely 1 mm deep. The Vicat softening temperature is defined in ISO 306 and ASTM D1525
