other: The test material did not catch fire on being exposed to air at room temperature of 27°C
Conclusions:
Trisodium 2,5-dichloro-4-(4-{[5-({4-chloro-6-[(4-sulfonatophenyl)amino]-1,3,5-triazin-2-yl}amino)-2-sulfonatophenyl]diazenyl}-3-methyl- 5-oxo-4,5-dihydro-1H-pyrazol-1-yl)benzenesulfonate did not catch fire on being exposed to air at room temperature of 27°C and atmospheric pressure of 966 hPa. This indicates that trisodium 2,5-dichloro-4-(4-{[5-({4-chloro-6-[(4-sulfonatophenyl)amino]-1,3,5-triazin-2-yl}amino)-2-sulfonatophenyl]diazenyl}-3-methyl- 5-oxo-4,5-dihydro-1H-pyrazol-1-yl)benzenesulfonate is not auto-flammable.
Executive summary:
