- Relative self-ignition temperature:
- 278 °C
Applicant's summary and conclusion
- Conclusions:
- The GLP study was performed according to EU method A.16 without deviations and therefore reliability of Klimisch 1 has been assigned. The auto ignition temperature has been determined at 278 °C.
- Executive summary:
The auto ignition temperature of the test substance was determined in a GLP test according to EU method A.16. The substance under test was placed in a wire basket with 8 mL volume in an oven at room temperature. The oven was heated up with a rate of 0.5 K/min up to 420 °C. The temperature of the center of the sample and the temperature of an inert reference sample, which was placed in the oven too, were recorded. For the purpose of this test, the temperature of the
oven at which the sample temperature reached 400 °C by self-heating is called the selfignition temperature.
In the temperature/time plot is a weak endothermic peak in the range from about 130 °C to 170 °C (oven temperature). In the range from 270 °C to 270 °C (oven temperature) is a strong exothermic peak with a temperature maximum of the substance from 496 °C. The sample temperature from 400 °C is reached at an oven temperature from 278 °C, which is the auto-ignition temperature.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
