CEAST HDT/Vicat Tester

Description

Test specimens are heated under an applied stress in an oil bath at a programmed heating rate. The temperature at which the specimens deflect is recorded. In the HDT Test, a specimen utilizes a three-point flexural stress state. The Vicat test uses a cylindrical probe to indent the specimen.
