Scope of standard

1.1 This test method describes a procedure for the assignment of a glass transition temperature (Tg) of materials on heating using thermomechanical measurements in tension. 1.2 This test method may be used as a complement to Test Method E1545 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 25 °C to 600 °C. This temperature range may be altered depending upon the instrumentation used. 1.4 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 1.6 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
