Results and discussion
Relative self-ignition temperature (solids)
- Key result
- Relative self-ignition temperature:
- ca. 260 °C
- Remarks on result:
- other:
- Remarks:
- at atm. press. of ca.1013.0 hPa
Any other information on results incl. tables
Self-heating of the test item as delivered was observed at 260 °C (small temperature rise up to ca. 330 °C).
The measurement of the mixture of the test item with kieselguhr (1:1) showed an exothermal reaction at 290 °C with a temperature rise up to above 800 °C.
Self-heating of the test substance occurs due to its decomposition.
Applicant's summary and conclusion
- Conclusions:
- The test substance shows weak self-heating at 260 °C. No classification as a self-heating substance class 4.2 of the transport regulations required.
- Executive summary:
Self-ignition of the test substance was determined by heating a sample in the Grewer oven. The test substance shows weak self-heating at 260 °C.
