Glass Transition Temperature - ASTM E1356 Plastic Test Standard

Glass Transition Temperature - ASTM E1356

The temperature at which an amorphous material experiences a physical change from a hard, or brittle condition to a flexible, or rubbery condition.

Since glass transition covers a range of temperatures, the reported glass transition temperature is generally the midpoint of the range. For materials with both crystalline and amorphous regions, only the amorphous region exhibits glass transition.
