Műanyagok. Hőre lágyuló műanyagok. A Vicat-féle lágyulási hőmérséklet (VST) meghatározása (ISO 306:2004)

Plastics. Thermoplastic materials. Determination of Vicat softening temperature (VST) (ISO 306:2004)

ISO 306:2004 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 °C/h Method B50 using a force of 50 N and a heating rate of 50 °C/h Method A120 using a force of 10 N and a heating rate of 120 °C/h Method B120 using a force of 50 N and a heating rate of 120 °C/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.
