ASTM E 794 : 2024

1.1This test method describes the determination of melting (and crystallization) temperatures of pure materials by differential scanning calorimetry (DSC) and differential thermal analysis (DTA).

1.2This test method is generally applicable to thermally stable materials with well-defined melting temperatures.

1.3The normal operating range is from −120 °C to 600 °C for DSC and 25 °C to 1500 °C for DTA. The temperature range can be extended depending upon the instrumentation used.

1.4The values stated in SI units are the standard. No other units of measurement are included in this standard.

1.5This 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.

1.6This 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.
