Results and discussion

Relative self-ignition temperature (solids)

Key result

Relative self-ignition temperature:

> 400 °C

Remarks on result:

no self ignition observed under the test conditions

Any other information on results incl. tables

All temperature measurements of both the oven and the test substance were plotted against time (Figure 1).

No endothermic or exothermic reactions were observed between 19C and 402C. After the experiment, the test Substance sample had changed from a white powder into a black charred residue and was Collected in a container placed below the Cube. There was no test substance left in the cube itself. From this it was concluded that most of the test substance sample had been molten during the experiment. The change of colour and consistency is an indication for decomposition or reaction.

Applicant's summary and conclusion

Conclusions:

The determination of the relative self-ignition temperature was performed in accordance with EEC-Directive 92/69 EEC, A. 16 "Relative self-ignition temperature for solids" (1992).
Approximately 8 cm test substance was heated in an oven. The temperatures of the oven and test substance were continuously recorded while the temperature of the oven was increased from 19C to 402°C at a rate of 0.5°C/minute. No endothermic or exothermic reactions were measured for the test substance.
In conclusion, v123109 The determination of the relative self-ignition temperature was performed in accordance with EEC-Directive 92/69 EEC, A. 16 "Relative self-ignition temperature for solids" (1992).
Approximately 8 cm test substance was heated in an oven. The temperatures of the oven and test substance were continuously recorded while the temperature of the oven was increased from 19C to 402°C at a rate of 0.5°C/minute. No endothermic or exothermic reactions Were measured for the test Substance.
In conclusion, v123109 (CH03824) is not self-ignitable according to the criteria as described in the method A. 16 of EEC-Directive 92/69 EEC.
