Results and discussion

Flammable solids
Test procedure:
burning rate test: preliminary screening test
Remarks on result:
substance does not ignite and propagate combustion either by burning with flame or smouldering along 200 mm of the powder train within the 2 minutes test period
Remarks:
The flame did not propagate down the train, but continued to burn for a few seconds after the flame source was removed.
