Abstract - (Show below) - (Hide below)

Defines four methods for the determination of the Vicat softening temperature (VST) of thermoplastic materials: a) Method A50 using a force of 10 N and a heating rate of 50 Degrees C/h; b) Method B50 using a force of 50 N and a heating rate of 50 Degrees C/h; c) Method A120 using a force of 10 N and a heating rate of 120 Degrees C/h; and d) Method B120 using a force of 50 N and a heating rate of 120 Degrees C/h.
