Specific details on test material used for the study:
Identity: FAT 40825/A
Batch number: CHU 297 / BOP 04/05
Purity: Organic part (Na-salt): approx. 83.7 %; All coloured components: approx. 80.54 %; Main component: approx. 59.1 %.
Appearance: Solid, black powder
Storage conditions: At room temperature at about 20 °C
Expiration date: December 31, 2010
Key result
Relative self-ignition temperature:
267 °C
Remarks on result:
preliminary test
Remarks:
An exothermic reaction starting at about 256 °C. A maximum temperature of 505 °C was measured in the sample cube during the exothermic reaction. At the end of the measurement, the test item was carbonized and black coloured.
Conclusions:
FAT 40825/A shows a relative self-ignition temperature at about 267 °C.
Executive summary:

The determination of the relative self-ignition temperature of the test item was performed according to the EEC Directive 92/69, Part A, Methods for the determination of physicochemical properties, A. 16 "Relative self-ignition temperature for solids", EEC Publication No. L383, December 1992. Applying a linear increase in temperature of about 0.5 °C/min, FAT 40825/A showed an exothermic reaction starting at about 256 °C. A maximum temperature of 505 °C was measured in the sample cube during the exothermic reaction. At the end of the measurement, the test item was carbonized and black coloured. FAT 40825/A shows a relative self-ignition temperature at about 267 °C. In conclusion, FAT 40825/A is auto-flammable under the conditions of the test.
