(Test Method)Standard Test Method for Temperature Calibration on Cooling of Differential Scanning Calorimeters
Standard Test Method for Temperature Calibration on Cooling of Differential Scanning Calorimeters
SIGNIFICANCE AND USE
5.1 This test method is useful in calibrating the temperature signal of a differential scanning calorimeter for cooling experiments such as the determination of crystallization temperatures in Test Method D3418 and Test Method E794.
5.2 This test method may be used for research, development, analytical, specification acceptance, quality assurance, and control purposes.
SCOPE
1.1 This test method covers the temperature calibration of differential scanning calorimeters on cooling using the difference between transition temperatures upon heating and cooling in the temperature range of 50 to 185°C. An offset in the indicated temperature between heating and cooling experiments, within this temperature range, may be used to provide temperature calibration on cooling at other temperature ranges.
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 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.
1.4 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.

4. Summary of Test Method
4.1 The temperature sensor of the DSC, used to determine the temperature of a transition, is located close to but external to the
test specimen. This arrangement causes the indicated temperature to lead or lag the actual specimen temperature on heating/cooling
causing the reported temperature to be higher on heating and lower on cooling than the actual specimen transition temperature.
A DSC apparatus temperature, that has been calibrated for heating experiments, needs to be re-calibrated for cooling experiments.
Such a calibration on cooling is performed using a liquid crystal material, the transition(s) for which are not subject to
super-heating or super-cooling.
4.2 The transition temperature of a rapid, non-superheating and non-supercooling transition is determined upon heating and
upon cooling. The difference between these two indicated temperatures provides an offset temperature value between heating and
