Key result
Remarks on result:
other: 4-acetamido-5-[[4-[[2-(sulphooxy)ethyl]sulphonyl]phenyl]azo]anthranilic acid, sodium salt ignites only when flame of bunsenburner have temp of 950°C is brought in contact with it.Thus it isconcluded the sub is flammable only-at high temp of 950°C.
Conclusions:
4-acetamido-5-[[4-[[2-(sulphooxy)ethyl]sulphonyl]phenyl]azo]anthranilic acid, sodium salt did not catch fire on being exposed to air at room temperature of 27°C pressure of 966 hPa. This indicates that 4-acetamido-5-[[4-[[2-(sulphooxy)ethyl]sulphonyl]phenyl]azo]anthranilic acid, sodium salt is not auto-flammable.
Executive summary:

4-acetamido-5-[[4-[[2-(sulphooxy)ethyl]sulphonyl]phenyl]azo]anthranilic acid, sodium salt did not catch fire on being exposed to air at room temperature of 27°C pressure of 966 hPa. This indicates that 4-acetamido-5-[[4-[[2-(sulphooxy)ethyl]sulphonyl]phenyl]azo]anthranilic acid, sodium salt is not auto-flammable.
