ASTM E 3142 : 2018 : REV A

1.1 This test method addresses the dependence of temperaturecalibration on the temperature rate-of-change. This testmethod describes the determination of the thermal lag ofthermal analysis apparatus and its application to the modificationof the temperature calibration for that apparatus obtainedat alternative linear temperature rates-of-change.1.2 This test method is applicable, but not limited to, thetemperature calibration of differential thermal analyzers(DTAs), diffeential scanning calorimeters (DSCs), thermogravimetricanalyzers (TGAs), thermomechanical analyzers(TMAs), and dynamic mechanical analyzers (DMAs).1.3 This test method is applicable only to apparatus demonstratinga linear relationship between indicated temperatureand temperature rate-of-change.1.4 The values stated in SI units are to be regarded as thestandard. No other units of measurement are included in thisstandard.1.5 This standard does not purport to address all of theafety concerns, if any, associated with its use. It is theresponsibility of the user of this standard to establish appropriatesafety, health, and environmental practices and determinethe applicability of regulatory limitations prior to use.1.6 This international standard was developed in accordancewith internationally recognized principles on standardizationestablished in the Decision on Principles for theDevelopment of International Standards, Guides and Recommendationsissued by the World Trade Organization TechnicalBarriers to Trade (TBT) Committee.
