ASTM E1356 – Glass Transition Temperatures by Differential Scanning Calorimetry (DSC)

We perform ASTM E1356 to assign the glass transition temperatures (Tg) of materials using differential scanning calorimetry or differential thermal analysis. The analysis is made by continuously monitoring the difference in heat flow when the sample is heated and/or cooled at a controlled rate. Knowing the Tg of a material provides important information about the material’s thermal history, processing conditions, stability, progress of chemical reactions, and mechanical and electrical behavior. ASTM E1356 testing is essential for any polymeric compound and also important for research, quality control, and specification acceptance. This test is applicable to amorphous materials or to partially crystalline materials containing amorphous regions that are stable and do not undergo decomposition or sublimation in the glass transition region.

Sample quantity required: 5 g or mL
