ASTM E1824-08 PDF

1.1 This test method describes a procedure for the assignment of a glass transition temperature of materials on heating using thermomechanical measurements under prescribed experimental conditions.

1.2 This test method may be used as a complement to Test Method E 1545 and is applicable to amorphous or to partially crystalline materials in the form of films, fibers, wires, etc. that are sufficiently rigid to inhibit extension during loading at ambient temperature.

1.3 The generally applicable temperature range for this test method is − 100 to 600 °C. This temperature range may be altered depending upon the instrumentation used.
