ASTM E1867-18

Standard Test Methods for Temperature Calibration of Dynamic Mechanical Analyzers

SIGNIFICANCE AND USE
5.1 Dynamic mechanical analyzers monitor changes in the viscoelastic properties of a material as a function of temperature and frequency, providing a means to quantify these changes. In most cases, the value to be assigned is the temperature of the transition (or event) under study. Therefore, the temperature axis (abscissa) of dynamic mechanical analysis thermal curves must be accurately calibrated by adjusting the apparent temperature scale to match the actual specimen temperature over the temperature range of interest.  
5.2 This test method is useful for research, quality assurance, and specification acceptance.
SCOPE
1.1 These test methods describes the temperature calibration of dynamic mechanical analyzers (DMA) from –100 °C to 300 °C.  
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.  
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 MethodMethods
4.1 In dynamic mechanical analysis, often large (for example, 1 g to 10 g), low thermal conductivity test specimens are
characterized while being mechanically supported using high thermal conductivity materials, while a temperature sensor is
free-floating in the atmosphere near the test specimen. Under temperature programming conditions, where the atmosphere
surrounding the test specimen is heated or cooled at rates up to 5°C/min, 5 °C/min, the temperature of the test specimen may lead
or lag that of the nearby temperature sensor. It is the purpose of this standard to calibrate the dynamic mechanical analyzer
temperature sensor so that the indicated temperature more closely approximates that of the test specimen. This In Methods A, B,
and C, this is accomplished by separating the test specimen calibration specimen (with its first order transition) from its mechanical
supports and from the surrounding atmosphere using a low thermal conductivity material. Three test methods of providing this
separation are provided.In Method D, the thermal lag between the temperature sensor and the test specimen is determined as a
function of heating rate. This value is then used to adjust the indicated temperature following calibration under isothermal ambient
conditions.
