ASTM E1640-99 Standard Test Method for Assignment of the Glass Transition Temperature By Dynamic Mechanical Analysis
standard by ASTM International, 08/10/1999
In stock
1.1 This test method covers the assignment of a glass transition temperature (Tg) of materials using dynamic mechanical analyzers.
1.2 This test method is applicable to thermoplastic polymers, thermoset polymers, and partially crystalline materials which are thermally stable in the glass transition region.
1.3 The applicable range of temperatures for this test method is dependent upon the instrumentation used, but, in order to encompass all materials, the minimum temperature should be about -150
