This test method describes the assessment of material thermal stability through the determination of the temperature at which the materials start to decompose or react and the extent of the mass change using thermogravimetry. The test method uses minimum quantities of material and is applicable over the temperature range from ambient to 800°C. The absence of reaction or decomposition is used as an indication of thermal stability in this test method under the experimental conditions used. This test method may be performed on solids or liquids, which do not sublime or vaporize in the temperature range of interest.
