Guideline:
EU Method A.10 (Flammability (Solids))

Source and lot/batch No.of test material: Sponsor and G316507
Key result
Test procedure:
burning rate test: preliminary screening test
Remarks on result:
other: The sample immediately discoloured to brown/black when in contact with the test flame. The sample glowed orange and ignited with a localised flame, but did not propagate or smoulder along the train

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.

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