Key result
Test procedure:
burning rate test: preliminary screening test
Moisture (wt %):
0.84
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:
Sample began to melt and it ignited with a medium size, orange, localised flame, this sustained for about 3 seconds after test flame was removed before extinguishing

If the burning time in the preliminary screening test is less than 4 minutes (40 minutes for metal powders), over a 200 mm distance, then the full range of burning rate tests are carried out unless no propagation is observed, otherwise no further testing is required. Materials are to be considered as highly flammable, when the time of burning in one of the six tests carried out according to the test procedure described is less than 45 seconds. Powders of metals or metal alloys are considered to be highly flammable when they can be ignited and the flame of the zone of reaction spreads over the whole sample in ten minutes or less.

Sample began to melt and it ignited with a medium size, orange, localised flame, this sustained for about 3 seconds after test flame was removed before extinguishing

Interpretation of results:
not classified based on GHS criteria
Conclusions:
From the preliminary screening (S/T) test the sample was seen to briefly ignite and therefore no further testing is required.
