Standard Test Method for Temperature Calibration of Dynamic Mechanical Analyzers Using Thermal Lag

Importancia y uso:

5.1 Dynamic mechanical analysis monitors changes in the viscoelastic properties (that is, storage modulus, loss modulus, tangent angle delta) of a material as a function of temperature and frequency, providing a means to quantify these changes. In many cases, the value to be assigned is the temperature of the transition or event under study. Therefore, the temperature axis (abscissa) of the dynamic mechanical analysis thermal curve must be accurately calibrated by adjusting the measured temperature scale to match the assumed specimen temperature over the temperature range of interest.
