Specific details on test material used for the study:

Identification: FAT 40851/A TE
Batch Number: TZ 5891 / BOP 02-09
Purity: 69.9 % all coloured components
Appearance: Orange powder
Expiry Date: July 31, 2014
Storage Conditions: At room temperature at about 20 °C

Relative self-ignition temperature:

322 °C

Remarks on result:

preliminary test

Remarks:

at atm. press. of 97.6 kPa

Conclusions:

Test substance is auto-flammable (at about 322 °C) under the conditions of the test.

Executive summary:

The determination of the relative self-ignition temperature of the test item test substance was performed under GLP according to the EEC Directive 92/69, EEC Publication No. L383, December 1992 and Council Regulation (EC) No. 440/2008, Part A, Methods for the determination of physico-chemical properties, A.16 “Relative self-ignition temperature for solids”. The test item was filled into a cube and heated in an oven. The temperatures of the oven and the sample were continuously recorded while the temperature of the oven was increased to approximately 400 °C. Applying a linear increase in temperature of the oven of about 0.5 °C/min, test substance showed an exothermic reaction starting at about 300 °C. A maximum temperature of 526 °C was measured in the sample cube during the exothermic reaction. At the end of the measurement, the test item was carbonized and colored black. Test substance shows a relative self-ignition temperature of about 322 °C. Therefore, the test item test substance is auto-flammable under the conditions of the test. The atmospheric pressure during the measurement was 97.6 kPa.
