Vicat Softening Temperature
This test determines the temperature at which a specified needle penetration occurs under a given load. A flat specimen, is placed in an oil bath which is heated at a constant rate and subjected to a standard load with a needle indenter. The temperature at which the specimen has deflected the specified amount is recorded.
- ASTM D1525
- ISO 306
