Scope

1.1 This test method describes the temperature calibration of differential thermal analyzers and differential scanning calorimeters over the temperature range from -40 to +2500°C.

1.2 Computer or electronic based instruments, techniques, or data manipulation equivalent to this test method may also be used.

1.3 SI units are the standard.

1.4 This test method is similar to ISO standard 11357-1.

1.5 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 7.

Significance and Use

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 or comparison of the resulting data to that of known standard materials is required.

This test method is useful in calibrating the temperature axis of differential scanning calorimeters and differential thermal analyzers.
