ASTM D 1525 / ASTM D 648

The tester is used to determine the Vicat softening temperature and the heat deflection temperature under load for plastics and thermoplastics.
Quantity:
  • GT-HVI
  • GT-TEST
  • 9024800000

Standards

l  ISO 75

l  ISO 306

l  ASTM D 1525  

l  ASTM D 648

 

Application

The tester is used to determine the Vicat softening temperature and the heat deflection temperature under load for plastics and thermoplastics.

The attained heat resistance rate of plastic material is a widely required parameter for product characterization, for quality control and for evaluating the conformity to the previewed applications.

 “HDT” test means

The test determines the temperature at which a specified deflection occurs when a standard test specimen is subjected to a bending stress, to produce one of the nominal surface stresses according to international standards.

This test is important for both quality control and research into plastics.

“VICAT” test means

The test determines the temperature at which a standard indenter penetrates 1mm into the surface of a test specimen under load.

It is used to establish the difference between many types of thermoplastic materials with regard to their softening properties.
