1. Scope | ||||||||||||
1.1 This test method covers the determination of the glass transition temperature of materials using differential scanning calorimetry or differential thermal analysis. 1.2 This test method 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. 1.3 The normal operating temperature range is from -120 to 500°C. The temperature range may be extended, depending upon the instrumentation used. 1.4 Computer or electronic-based instruments, techniques, or data treatment equivalent to this test method may also be used. Users of this test method are expressly advised that all such instruments or techniques may not be equivalent. It is the responsibility of the user of this standard to determine the necessary equivalency prior to use. In the case of dispute, only the manual procedures described in this test method are to be considered valid. 1.5 This standard does not purport to address the safety problems associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. |
