Results and discussion
Relative self-ignition temperature (solids)
- Relative self-ignition temperature:
- 290 °C
Any other information on results incl. tables
The pure sample showed self-heating starting from 290 °C (max. temp. ca 380 °C).
It liquefied during the test and flowed partially out of the basket. The remaining amount in the wire basket showed self-ignition.
The mixture with kieselguhr (1:1; prevents the sample from running out of the wire basket) showed self-ignition starting from 290 °C with a temperature rise to above 700 °C due to an oxidation reaction of the test substance with kieselguhr.
Applicant's summary and conclusion
- Conclusions:
- The pure test substance showed self-heating starting from 290 °C. The test item is not a self-heating substance according to UN class 4.2 and GHS/CLP.
- Executive summary:
Self-heating of the test substance was analysed by a screening test in the Grewer oven according to VDI 2263, sheet 1. The pure test substance showed self-heating starting from 290 °C. The test item is not a self-heating substance.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
