Key result
Remarks on result:
other: 4-[(3-aminobenzoyl)amino]-5-hydroxynaphthalene-1,7-disulphonic acid ignites only when flame of bunsen burner having temp 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:
4-[(3-aminobenzoyl)amino]-5-hydroxynaphthalene-1,7-disulphonic acid did not catch fire on being exposed to air at room temperature of 27°C pressure of 966 hPa. This indicates that 4-[(3-aminobenzoyl)amino]-5-hydroxynaphthalene-1,7-disulphonic acid is not auto-flammable.
Executive summary:

4-[(3-aminobenzoyl)amino]-5-hydroxynaphthalene-1,7-disulphonic acid did not catch fire on being exposed to air at room temperature of 27°C pressure of 966 hPa. This indicates that 4-[(3-aminobenzoyl)amino]-5-hydroxynaphthalene-1,7-disulphonic acid is not auto-flammable.
