Results and discussion

Flammable solids
Key result
Test procedure:
burning time over 250 mm for metal powders or metal alloys
Remarks on result:
other: In the preliminary screening test following the EU method and UN method, the test item was heated with the flame of a teclu burner. The test item changed the colour into grey. No signs of ignition were observed.

Applicant's summary and conclusion

Interpretation of results:
not classified based on GHS criteria
Conclusions:
No ignition was observed throughout the course of the test.
The test item Ammonium hexafluorocirconate should be considered as not highly flammable
(for EU regulations) and non-flammable solid (for UN regulations), resp.
No observations were made which might cause doubts concerning the validity of the study
outcome.
