ASTM E 2069 : 2025

1.1This test method describes the temperature calibration of differential scanning calorimeters (DSCs) on cooling using the difference between transition temperatures upon heating and cooling in the temperature range of 65 °C to 420 °C. Within this temperature range, an offset in the indicated temperature between heating and cooling experiments may be used to provide temperature calibration on cooling at other temperature ranges.

1.2SI units are the standard. No other units of measurement are included in this standard.

1.3Test Method E3142 is an alternative to this test method.

1.4This 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. Specific precautionary statements are given in Section 6.

1.5This 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.
