Specific details on test material used for the study:
Identity: FAT 40'574/B
Batch: WP 23/99
Purity: Approx 75 %
Appearance: Solid, dark-red powder
Storage: At room temperature at about 20 °C
Expiration Date: 08 February 2006
Relative self-ignition temperature:
ca. 297 °C
Remarks on result:
other: Applying a linear increase in temperature of about 0.5 °C/min, FAT 40'574/B showed an exothermic reaction starting at about 200 °C. A maximum temperature of 514 °C was measured in the sample cube during the exothermic reaction.
Remarks:
at atm. press. of ca.1013.25 hPa
Conclusions:
FAT 40574/B shows a relative self-ignition temperature at about 297 °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 297 °C.
