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.
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.
1.3 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 and health practices and determine the applicability of regulatory limitations prior to use. Specific precautionary statements are given in Section 6.
