Brief description of the test.
Sample is heated under isoperibolic conditions ( same temperature) for 72 hours to study the self ignition when placed in a wire basket of appropriate size and under continuous flow of air. Self ignition is said to be observed if the temperature difference between the sample and the oven exceeds 20°C
GLP compliance:
not specified

Key result
Remarks on result:
other: No auto Ignition observed till 1900 degC though DTA indicated decomposition (max) at 183.640 degC.
Conclusions:
No auto Ignition observed for chemical N-(4-{bis[4-(dimethylamino)phenyl]methylene}cyclohexa-2,5-dien-1-ylidene)-N-methylmethanaminium chloride till 1900 degC though DTA indicated decomposition (max) at 183.640 degC. This indicates that the chemical N-(4-{bis[4-(dimethylamino)phenyl]methylene} cyclohexa-2,5-dien- 1-ylidene)-N- methylmethanaminium chloride is not auto-flammable till 1900 degC.
Executive summary:

No auto Ignition observed for chemical N-(4-{bis[4-(dimethylamino)phenyl]methylene}cyclohexa-2,5-dien-1-ylidene) -N-methylmethanaminium chloride till 1900 degC though DTA indicated decomposition (max) at 183.640 degC. This indicates that the chemical N-(4-{bis[4-(dimethylamino)phenyl]methylene} cyclohexa-2,5-dien- 1-ylidene)-N- methylmethanaminium chloride is not auto-flammable till 1900 degC.
