    Significance and Use

    5.1 Differing temperature rates-of-change may be required for different measurements (for example, Test Method E698). Temperature calibration changes as a function of temperature rate-of-change. The use of the known thermal lag of an apparatus may be used to adjust the temperature calibration of the apparatus obtained at one temperature rate-of-change with that at another required for a given applications. This adjustment procedure for temperature calibration is described in 8.1.

    5.2 This test method may be used in research, quality assurance, and specification acceptance.

    1. Scope

    1.1 This test method addresses the dependence of temperature calibration on the temperature rate-of-change. This test method describes the determination of the thermal lag of thermal analysis apparatus and its application to the modification of the temperature calibration for that apparatus obtained at alternative linear temperature rates-of-change.

    1.2 This test method is applicable, but not limited to, the temperature calibration of differential thermal analyzers (DTAs), differential scanning calorimeters (DSCs), thermogravimetric analyzers (TGAs), thermomechanical analyzers (TMAs), and dynamic mechanical analyzers (DMAs).

    1.3 This test method is applicable only to apparatus demonstrating a linear relationship between indicated temperature and temperature rate-of-change.

    1.4 The values stated in SI units are to be regarded as the standard. No other units of measurement are included in this standard.

    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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

    1.6 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.
