Applicant's summary and conclusion
- Conclusions:
- The self-ignition temperature of cerium metal was determined to be 290.5 °C at 1 atm.
- Executive summary:
The determination of the auto flammability of cerium was performed according to the EU A16 method "Relative self-ignition temperature for solids" according to the Council Regulation (EC) No 440/2008.
A certain volume of the substance under test is placed in an oven at room temperature; the temperature/time curve relating to conditions in the centre of the sample is recorded while the temperature of the oven is increased to 400 oC, or to the melting point if lower, at a rate of 0,5 oC/min. For the purpose of this test, the temperature of the oven at which the sample temperature reaches 400 oC by self-heating is called the selfignition temperature.
The self-ignition temperature of cerium metal was determined to be 290.5 °C at 1 atm.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
