Key result

Test procedure:

burning rate test: preliminary screening test

Burning time:

2 min

Safety Pre-Test

The test item burned with a green, blue and orange flame. A small green residue was left.

Preliminary Screening Test

In the preliminary screening test following the EU and the UN method, the test item was heated with the flame of a teclu burner. The flame became green blue and orange when it got in touch with the test item. After heating, the test item was grey-greenish coloured. No ignition occurred within two minutes. No sign of ignition within two minutes.

Results and Discussion

No ignition was observed throughout the course of the test.

The test itemCupric Bromideshould 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.

Interpretation of results:

not classified based on GHS criteria

Conclusions:

Under the test conditions of an experimental study performed under GLP conditions following EU-Method A.10 and UN N.1, the test item Cupric Bromide can be considered as not highly flammable (for EU regulations) or as a non-flammable solid (for UN regulations).

Executive summary:

For that endpoint, an experimental study was available to determine the flammability of the test item Cupric Bromide following EU-Method A.10 and UN N.1 and under GLP conditions.

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 burned with a green, blue and orange flame. A small green residue was left.

 

In the preliminary screening test following the EU and UN method, the test item was heated with the flame of a teclu burner. The flame became green blue and orange when it got in touch with the test item. After heating, the test item was grey-greenish coloured. No ignition occurred within two minutes.

Therefore, the test item Cupric Bromide should be considered as:

- not highly flammable (for EU regulations)

- non-flammable solid (for UN regulations)

No observations were made which might cause doubts concerning the validity of the study outcome. In addition, the study was conducted without any deviation from the study guidelines. Therefore, this study can be regarded as valid for that endpoint.
