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:
Dialuminium tris(4-hydroxy-3-((4-sulphonato-1-naphthyl)azo)naphthalenesulphonate) did not catch fire on being exposed to air at room temperature of 27°Cpressure of 966 hPa. This indicates that Dialuminium tris(4-hydroxy-3-((4-sulphonato-1-naphthyl)azo)naphthalenesulphonate) is not auto-flammable.
Executive summary:

Dialuminium tris(4-hydroxy-3-((4-sulphonato-1-naphthyl)azo)naphthalenesulphonate) did not catch fire on being exposed to air at room temperature of 27°Cpressure of 966 hPa. This indicates that  Dialuminium tris(4-hydroxy-3-((4-sulphonato-1-naphthyl)azo)naphthalenesulphonate) is not auto-flammable.
