At a glance
Thermogravimetric analysis follows mass change under a specified thermal programme. It can assist material investigation, but the curve should not be treated as a direct map of service-temperature limits.
Key points
- Atmosphere, heating rate and specimen composition influence the observed response.
- State the test conditions and use appropriate reference materials or validated analysis when estimating composition.
- TGA is not a reaction-to-fire classification and does not reproduce every manufacturing condition.
Technical context #
Atmosphere, heating rate and specimen composition influence the observed response. Overlapping processes may make simple separation of wood, polymer and additives unreliable. Residue is not automatically an exact measure of a single ingredient.
What to measure and document #
State the test conditions and use appropriate reference materials or validated analysis when estimating composition. Report uncertainty and limitations. Avoid assigning every curve feature to one constituent without supporting evidence.
Implications for development and specification #
TGA is not a reaction-to-fire classification and does not reproduce every manufacturing condition. Use it for the defined analytical question, then obtain the relevant process or product tests. A laboratory decomposition observation should not become an unsupported installation temperature claim.
Related reading and evidence limits #
