Standard Test Method for Rapid Thermal Degradation of Solid Electrical Insulating Materials By Thermogravimetric Method (TGA)

Importancia y uso:

5.1 Thermogravimetry is useful in determining the dynamic functional effect of temperature on the amount of volatile materials leaving a specimen as the latter is heated progressively to higher temperatures. TGA is useful for process control, process development, material evaluation, and for identification and quality control in specifications.

5.2 The thermal stability of a material is often associated with the degree and time rate of mass loss as a function of temperature. In these cases, TGA curves are available to be used as a preliminary screening method in the evaluation of relative behavior of insulating materials of the same generic family.

5.3 The functional temperature-life relationship of an insulating material in any given application depends on a number of service and environmental factors. Therefore, the information obtained from TGA curves is not adequate by itself to describe the thermal capability of an insulating material.

5.4 Refer to the appendix for further discussion of the interpretation of TGA data.
