Flammable solids

Key result

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 item melted to a pale fluid which became quickly darker. No signs of flammability were visible.

Applicant's summary and conclusion

Interpretation of results:

not classified based on GHS criteria

Conclusions:

The flammability was determined according to a scientifically valid method, i.e. EU method A.10 under GLP, in a well-documented study, hence, the following result for the test material can be considered as reliable:
No ignition was observed throughout the course of the test.
The test item pyridine-2-carbaldehyde oxime should be considered as not highly flammable (for EU regulations) resp. non-flammable solid (for UN regulations).
No observations were made which might cause doubts concerning the validity of the study outcome.
The substance does not need to be classified as flammable solid.

Executive summary:

The flammability of pyridine-2-carbaldehyde oxime was determined following EU-Method A.10 and UN N.1 under GLP.

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 started to melt to a dark fluid and the molten mass burned with a sooting flame.

In the preliminary screening test following the EU and UN methods, the test item was heated with the flame of a teclu burner. The test item melt to a pale fluid and became quickly darker. No signs of flammability were visible. Therefore, the test item pyridine-2-carbaldehyde oxime should be considered as:

not highly flammable (for EU regulations)

non-flammable solid (for UN regulations).
