ASTM E967-18
(Test Method)Standard Test Method for Temperature Calibration of Differential Scanning Calorimeters and Differential Thermal Analyzers
Standard Test Method for Temperature Calibration of Differential Scanning Calorimeters and Differential Thermal Analyzers
SIGNIFICANCE AND USE
5.1 Differential scanning calorimeters and differential thermal analyzers are used to determine the transition temperatures of materials. For this information to be meaningful in an absolute sense, temperature calibration of the apparatus and comparison of the resulting data to that of known standard materials is required.
5.2 This test method is useful in calibrating the temperature axis of differential scanning calorimeters and differential thermal analyzers.
SCOPE
1.1 This test method describes the temperature calibration of differential thermal analyzers and differential scanning calorimeters over the temperature range from −40°C to +2000°C.
1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
1.3 This test method is similar to ISO standard 11357–1.
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, health, and environmental practices and determine the applicability of regulatory limitations prior to use. Specific precautionary statements are given in Section 7.
1.5 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.

This document is not an ASTM standard and is intended only to provide the user of an ASTM standard an indication of what changes have been made to the previous version. Because
it may not be technically possible to adequately depict all changes accurately, ASTM recommends that users consult prior editions as appropriate. In all cases only the current version

3. Terminology
3.1 Definitions—Specific technical terms used in this test method are defined in Terminologies E473 and E1142.
4. Summary of Test Method
4.1 This test method consists of heating the calibration materials at a controlled rate in a controlled atmosphere through a region
of known thermal transition. The heat flow into the calibration material or the difference of temperature between the calibration
material and a reference sample and a reference material is monitored and continuously recorded. A transition is marked by the
absorption of energy by the specimen resulting in a corresponding endothermic peak in the heating curve.
NOTE 1—Heat flow calibrations are sometimes determined in conjunction with temperature calibration. Some differential scanning calorimeters permit
both heat flow and temperature calibrations to be obtained from the same experimental procedure.
5. Significance and Use
5.1 Differential scanning calorimeters and differential thermal analyzers are used to determine the transition temperatures of
materials. For this information to be meaningful in an absolute sense, temperature calibration of the apparatus orand comparison
of the resulting data to that of known standard materials is required.
