Key result
Remarks on result:
other: The given chemical (CAS no. 83949-60-4) 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:
 Lithium bis[2-[(4,5-dihydro-3-methyl-5-oxo-1-phenyl-1H-pyrazol-4-yl)azo] benzoato(2-)]chromate(1-) (CAS no. 83949-60-4) did not catch fire on being exposed to air at room temperature of 27°C pressure of 966 hPa. This indicates that  Lithium bis[2-[(4,5-dihydro-3-methyl-5-oxo-1-phenyl-1H-pyrazol-4-yl)azo] benzoato(2-)]chromate(1-) (CAS no. 83949-60-4) is not auto-flammable.
Executive summary:

 Lithium bis[2-[(4,5-dihydro-3-methyl-5-oxo-1-phenyl-1H-pyrazol-4-yl)azo] benzoato(2-)]chromate(1-) (CAS no. 83949-60-4) did not catch fire on being exposed to air at room temperature of 27°C pressure of 966 hPa. This indicates that  Lithium bis[2-[(4,5-dihydro-3-methyl-5-oxo-1-phenyl-1H-pyrazol-4-yl)azo] benzoato(2-)]chromate(1-) (CAS no. 83949-60-4) is not auto-flammable.
