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 test substance was shaped in a prism as prescribed by the method. The sample, in contact with the flame of a Bunsen, melts slowly and after about 45 seconds starts to spread on the plate. No flame has been observed; after moving away the source, smoke is observed only few seconds. Considering the absence of propagation during the preliminary test, the speed of combustion test wasn't performed.

Applicant's summary and conclusion

Interpretation of results:

not classified based on GHS criteria
