Remarks:

Result:
79 s

Any other information on results incl. tables

Preliminary Results:

The test substance/cellulose mixture burned briefly (10 seconds) on application of the test flame, but only the tip of the cone had burned when the flame extinguished. In comparison, the barium nitrate reference burned vigorously to completion in 50 seconds. As ATBS was not clearly oxidising, a definitive test was performed

Definitive Results:

The burn time (200 mm) for a reference mixture of 3 parts barium nitrate to 2 parts of cellulose was 79 seconds.

The following burn times (200 mm) were obtained for 10 to 90% mixtures of A TBS with cellulose.
