(Test Method)Standard Test Method for Temperature Calibration of Thermomechanical Analyzers
Standard Test Method for Temperature Calibration of Thermomechanical Analyzers
SIGNIFICANCE AND USE
Thermomechanical analyzers are employed in their various modes of operation (penetration, expansion, flexure, etc.) to characterize a wide range of materials. In most cases, the value to be assigned in thermomechanical measurements is the temperature of the transition (or event) under study. Therefore, the temperature axis (abscissa) of all TMA thermal curves must be accurately calibrated either by direct reading of a temperature sensor or by adjusting the programmer temperature to match the actual temperature over the temperature range of interest.
SCOPE
1.1 This test method describes the temperature calibration of thermomechanical analyzers from − 50 to 1100 °C. (See Note 1.)
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 is similar to ISO 11359–1 but addresses a larger temperature range and utilizes additional calibration materials.
1.4 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 and Note 9.

4. Summary of Test Method
4.1 An equation is developed for the linear correlation of the experimentally observed program temperature and the actual
melting temperature for known melting standards. This is accomplished through the use of a thermomechanical analyzer with a
penetration probe to obtain the onset temperatures for two melting point standards.An alternate, one-point method of temperature
calibration, is also given for use over very narrow temperature ranges. (See Note 32.)
NOTE2—This 1—This test method may be used for calibrating thermomechanical analyzers at temperatures outside this range of temperature.
However, the accuracy of the calibration will be no better than that of the temperature standards used.
