Results and discussion

Flammable solids

Key result

Test procedure:

burning rate test: preliminary screening test

Burning time:

> 2 min

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 Allyltributylphosphonium chloride should be considered as not highly flammable
(for EU regulations) and as non-flammable solid (for UN regulations),
No observations were made which might cause doubts concerning the validity of the study
outcome.

Executive summary:

First, a safety test was performed. A small amount of the test item was heated on a magnesia

groove with a gas burner in order to derive safety precautions. The test item melted and

burned with a yellow sooting flame. Then, the test item got darker (brownish).

In the preliminary screening test following the EU and UN method, the test item was heated

with the flame of a teclu burner. The test item melted to a beige liquid. No signs of ignition

were observed.

Therefore, the test item Allyltributylphosphonium chloride should be considered as

not highly flammable (for EU regulations)

non-flammable solid (for UN regulations)
