Key result
Remarks on result:
other: The test substance ignites only when the flame of bunsen burner having temperature of 950°C is brought in contact with it.Thus it can be concluded that substance is flammable only at high temperature of about 950°C.
Conclusions:
3,4,5,6-tetrachloro-2-(2,4,5,7-tetrabromo-3,6-dihydroxyxanthen-9-yl)benzoic acid, aluminium salt did not catch fire on being exposed to air at room temperature of 27°Cpressure of 966 hPa. This indicates that 3,4,5,6-tetrachloro-2-(2,4,5,7-tetrabromo-3,6-dihydroxyxanthen-9-yl)benzoic acid, aluminium salt is not auto-flammable.
Executive summary:

3,4,5,6-tetrachloro-2-(2,4,5,7-tetrabromo-3,6-dihydroxyxanthen-9-yl)benzoic acid, aluminium salt did not catch fire on being exposed to air at room temperature of 27°Cpressure of 966 hPa. This indicates that  3,4,5,6-tetrachloro-2-(2,4,5,7-tetrabromo-3,6-dihydroxyxanthen-9-yl)benzoic acid, aluminium salt is not auto-flammable.
