Vicat softening point of plastics

The Vicat softening point is the temperature at which a flat-pointed needle penetrates the sample to a thickness of 1 mm when loaded with a 10 N or 50 N load. In the test, the sample is placed in an oil bath that is heated at a rate of 50 °C/h or 120 °C/h, and the needle is placed on the surface of the sample. The test gives you the temperature at which the needle has penetrated 1 mm deep into the sample. The test price includes the measurement of the Vicat softening point as a triplicate with method A50, A120, B50, or B120.
