Summary

ISO 306:2013 specifies four methods for the determination of the Vicat softening temperature (VST) of thermoplastic materials:

method A50 using a force of 10 N and a heating rate of 50 K/ h
method B50 using a force of 50 N and a heating rate of 50 K/ h
method A120 using a force of 10 N and a heating rate of 120 K/ h
method B120 using a force of 50 N and a heating rate of 120 K/ h.

The methods specified are applicable only to thermoplastics, for which they give a measure of the temperature at which the thermoplastics start to soften rapidly.
