ASTM E1363 Temperature Calibration of Thermo mechanical Analyzers

Scope:

ASTM E1363 test method covers the characteristics of thermo-mechanical analyzers. Their role in penetration, expansion, and flexure is studied. The method determines their applications and specifications. The method proceeds with the quality check, heat treatment, and the testing of the chemical composition of materials.  The results obtained from this method help in quality control, research, and performance evaluation of thermo-mechanical analyzers.

Procedure:

In ASTM E1363 testing, for known melting standards, an equation is developed for the linear link between the experimentally measured program temperature and the actual melting temperature. This is performed by obtaining the onset temperatures for two melting point standards using a thermo-mechanical analyzer with a penetrating probe. For use over very small temperature ranges, an additional one-point technique of temperature calibration is also provided.

Specimen Size:

Specimen size should be as per the requirements. In this ASTM E1363 test, 10 to 20 mg of the specimen is taken. 

Data:

The slope and intercept can be determined using the equation where:

S = slope (nominal value = 1.00),

I = intercept,

T_a1 = reference transition temperature for Reference Material 1 

T_a2 = reference transition temperature for Reference Material 2 

T₀₁ = experimentally observed transition onset temperature for Reference Material 1,

T₀₂ = experimentally observed transition onset temperature for Reference Material 2.

Conclusion:

The ASTM E1363 test method is specifically important for the quality assurance and durability check of thermo-mechanical analyzers. Their role in detecting temperature is studied.
