This database was created by the Reactive Chemical Safety Center (RCSC) of East China University of Science and Technology (responsible for the test database) and Suzhou Huache Safety Technology Co., LTD. (responsible for the incident database) cooperation.

Testing data can be retrieved by chemical name or other characteristics. For example "trinitrotoluene" or "TNT"

This database has been under continuous development since the beginning of 2024. The data in this database are all experimental test results. Currently, more than 2,000 test data have been uploaded. It plans to add more than 2,000 new test data annually, aiming to build a worldwide shared database of thermal stability of chemicals. We freely shares the onset temperature and total energy of these experimental tests. The full experimental report needs to be purchased which includes sample details, DSC spectra, pictures of sample before and after the test, FTIR spectra, etc (Report Examples).

Please note: The data contained in the RCSC experimental test database is based on a specific sample obtained from a supplier. We have tried our best to ensure the reliability of the data during the testing process, but we do not exclude the differences in the data introduced by supplier differences, sample impurities, long-term storage deterioration, test method error, human error, etc. Therefore, we recommend that RCSC experimental test data only be used as a reference, and we will not be responsible for any loss caused by any reason.

Remark：

1, the center free to share two key parameters: onset temperature and total energy.The onset temperature can help to evaluate the safety risk from this decomposition reaction in a certain process (except storage). When the maximum temperature of the normal process or the temperature of the hot source is lower than the onset temperature of DSC minus 100 °C, the safety risk from this decomposition reaction itself is low; When higher, it is recommended to do a more specific reactivity safety risk analysis; The autocatalytic strength of decomposition reaction needs to be analyzed in storage condition, which does not follow such simple 100℃ rule. The total energy can help to determine roughly how dangerous the decomposition reaction is when it occurs. Especially, chemicals with a total energy greater than 1000J/g could explode. With our data and total mass, TNT chemical explosion model could estiamte the damage area for such explosion event in plants.

2, the database of DSC test methods refer to ASTM E537-24 and T/CCSAS055-2025: The test conditions of most DSC experiments are glass capillary crucible, 0~400℃, 10℃/min, repeated twice, the headspace is nitrogen, and the sample leakage is less than 5% (the specific test conditions are subject to the experiment report).

3. ARC test method of this database:The test conditions of most ARC experiments are Harbin alloy sample pool, sample size is 3~4g, room temperature ~350℃, heating interval is 5℃, waiting time is 20min, search time is 10min, temperature rise rate threshold is 0.02℃/min, and the headspace is air (the specific test conditions are subject to the experiment report)）。
