- Scope
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 can be useful for process control, process development, material evaluation, and for identification and quality control in specifications.
The thermal stability of a material can be associated with the degree and time rate of mass loss as a function of temperature. TGA curves can, therefore, be used as a preliminary screen method in the evaluation of relative behavior of insulating materials of the same generic family.
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.
Refer to the Appendix for further discussion of the interpretation of TGA data.
1.1 This test method outlines a procedure for obtaining thermogravimetric (TGA) data on solid polymeric materials intended for use as electrical insulating materials.
1.2 Do not use this standard to quantify an estimate of the long-term thermal capability for any electrical insulating material. If a relationship exists between TGA and the long-term thermal capabilities of a material, then that fact must be established and made public, preferably by comparing data between a candidate and another material known to display similar failure modes.
1.3 The values stated in SI units are the standard.
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.
