Learn about the Vicat softening temperature test method, which involves using a flat-ended needle loaded with a specified mass to test the thermal stability of PMMA. The test specimen and needle are heated at a specific rate, and the temperature at which the needle penetrates the PMMA to a depth of 1mm is recorded as the vicat softening point.
