1.1 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.
1.2 The absence of reaction or decomposition is used as an indication of thermal stability in this test method under the experimental conditions used.
1.3 This test method may be performed on solids or liquids, which do not sublime or vaporize in the temperature range of interest.
1.4 This test method shall not be used by itself to establish a safe operating or storage temperature. It may be used in conjunction with other test methods (for example, Test Methods and , and Guide ) as part of a hazard analysis of a material.
1.5 This test method is normally applicable to reaction or decomposition occurring in the range from room temperature to 800°C. The temperature range may be extended depending on the instrumentation used.
1.6 This test method may be performed in an inert, a reactive or self-generated atmosphere.
1.7 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
1.8 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, health and environmental practices and determine the applicability of regulatory limitations prior to use.
1.9 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
