ISO 75 and ISO 306: HDT and VST Tests on High Temperature Polymers
Traditionally silicone oil has been the most popular medium for performing heat deflection temperature (HDT) and vicat softening temperature (VST) tests on polymers.

Traditionally silicone oil has been the most popular medium for performing heat deflection temperature (HDT) and vicat softening temperature (VST) tests on polymers. The test principle and procedure are simple, and although silicone oil based test systems are very well established, they can be used safely only up to a maximum temperature of 280°C.
