Vicat Softening Temperature Test Equipment

1. Introduction

The vicat softening temperature test equipment is designed to meet the requirements of IEC62368-1 clause 5.41.10.2 and ISO306 for testing VST of thermoplastic materials.

The temperature at which a standard indenting tip with a flat point penetrates 1mm into the surface of a plastic test specimen is determined. The indenting tip exerts a specified force perpendicular to the test specimen, while the specimen is heated at a specified and uniform rate. The measured temperature of the specimen as close as possible to the indented area at 1mm penetration is quoted as the VST.
