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.
