Preliminary Test

The cone ignited and burnt with an orange flame for 2 seconds, leaving the surface of the pile charred.

 

Main Test

The results of the test are detailed in the following tables.

 

Reference Mixtures

% Barium Nitrate	Observations	Burning Time(s)	Burning Rate (mm/s)
10	The pile burnt with a yellow/blue flame, which emitted grey fumes and left grey charred remains.	244	0.820
20	The pile burnt with a yellow/blue flame, which emitted grey fumes and left grey charred remains.	178	1.12
30	The pile burnt with a yellow/blue flame, which emitted grey fumes and left grey charred remains.	182	1.10
40	The pile burnt with a yellow/green flame, which emitted grey fumes and left grey charred remains.	188	1.06
50	The pile burnt with a yellow/green flame, which emitted yellow sparks and grey fumes leaving grey charred remains.	131	1.53
60	The pile burnt with a yellow/green flame, which emitted yellow sparks and grey fumes leaving grey charred remains.	106	1.89
70	The pile burnt with a yellow/green flame, which emitted grey fumes and left grey/white charred remains.	131	1.53
80	The pile burnt with a yellow/green flame emitting grey fumes but self-extinguished after propagating 32 mm.	-	-
90	The pile failed to ignite.	-	-

Maximum burning rate = 1.887 mm/s.

Test Item:
