1.1 This test method describes the assignment of the glass transition temperature of materials using modulated temperature differential scanning calorimetry (MTDSC) over the temperature range from -120 to + 600 °C. The temperature range may be extended depending upon the instrumentation used.

1.2 SI units are the standard.

1.3 There are no ISO equivalents to this standard.

1.4 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 and health practices and determine the applicability of regulatory limitations prior to use.
