Results and discussion
Flammable solids
- Key result
- Test procedure:
- burning time over 250 mm for metal powders or metal alloys
- 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
Applicant's summary and conclusion
- Interpretation of results:
- other: Not highly flammable (for EU regulations) and non-flammable solid (for UN regulations).
- Conclusions:
- The test item was heated with the flame of a gas burner for two minutes. Since ignition did not occur within two minutes, the test substance was classified as not highly flammable (for EU regulations) and non-flammable solid (for UN regulations), resp. No determination of burning rate was necessary.
