Standard Test Method for Assignment of the Glass Transition Temperature by Thermomechanical Analysis

Importancia y uso:

5.1 The glass transition is dependent on the thermal history of the material to be tested. For amorphous and semicrystalline materials the assignment of the glass transition temperature may lead to important information about thermal history, processing conditions, stability, progress of chemical reactions, and mechanical and electrical behavior.

5.2 Thermomechanical analysis provides a rapid means of detecting changes in hardness or linear expansion associated with the glass transition.

5.3 This test method is useful for research and development, quality control, and specification acceptance.
