Remarks on result:

other: Using a linear increase in temperature of about 0.5 °C/min, FAT 40'571/A showed no relevant exothermic reaction. At the end of the measurement FAT 40'571/A had lost about 34 % of its weight and was coloured black.

Using a linear increase in temperature of about 0.5 °C/min, FAT 40'571/A showed no relevant exothermic reaction. At the end of the measurement FAT 40'571/A had lost about 34 % of ist weight and was coloured black.

Conclusions:

The FAT 40'571/A is not auto-flammable.

Executive summary:

The determination of the relative self-ignition temperature of the FAT 40'571/A was performed according to the EEC Directive 92/69, A. 16. Using a linear increase in temperature of about 0.5 °C/min, FAT 40'571/A showed no relevant exothermic reaction. At the end of the measurement FAT 40'571/A had lost about 34 % of its weight and was coloured black.

 

In conclusion, FAT 40'571/A is not auto-flammable, according to the criteria as described in the guideline.
