Overview
- Purpose Of Procedure: To determine the temperature at which a material softens under a specific load.
- Definition Of Terms: The Vicat softening temperature is the temperature at which a flat-ended needle penetrates the specimen to a depth of 1 mm.
- This temperature indicates the material's performance in elevated temperature applications.
