Specific details on test material used for the study:

Identity: FAT 40827/A
Batch: T2 5572 BOP 01/06
Purity: determined in this study
Appearance: black sticky powder
Expiration date: 28.02.2011
Storage: at room temperature

Relative self-ignition temperature:

282 °C

Remarks on result:

other: The exact pressure was not reported. But the test was performed under ambient atmospheric pressure, which is considered to be close to 1013. kPa.

The test item showed an exothermic reaction starting at 275 °C. A maximum temperature of about 560 °C was measured in the sample cube during the exothermic reaction. At the end of the measurement, the test item was carbonized.

Conclusions:

The test material shows a relative self-ignition temperature at about 282 °C.

Executive summary:

The auto-ignition temperature of the test item was determined in a study conducted according to the EU Method A.15. The auto-ignition temperature, as obtained by this method, is the minimum ambient temperature expressed in °C at which a certain volume of a substance ignites under defined conditions. The temperature of the oven and the sample were continuously recorded while the temperature of the oven was increased to approximately 400 °C at a rate of about 0.5 °C/min. Based on the findings of the study, the test material shows a relative self-ignition temperature at about 282 °C.

Description of key information
