Computer System Vika Thermal Deformation Testing Machine (LVDT Sensor)

Application of hot deformation and Vicat softening point temperature measuring instrument:The thermal deformation and Vicat softening point temperature tester is used to measure the thermal deformation and Vicat softening point of non-metallic materials such as plastics, rubber, nylon, and electrical insulation materials.

definition:

Thermal deformation:Deformation temperature under load (bending stress under three-point loading) (determination of load deformation temperature);

Vicat softening point temperature:The temperature at which the specified needle penetration phenomenon occurs in a plastic sample under controlled testing conditions (plastic Vicat softening temperature test method).

Standard for thermal deformation and Vicat softening point temperature measuring instrument:ASTM-D1525、 ASTM-D648、DIN53460、DIN53461、ISO-306、ISO-75；
