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

Findings:

Safety Pre-Test:

A small amount of the test item was heated on a magnesia groove with a gas burner. Glowing was observed. The test item showed no signs of ignition.

Preliminary screening test:

The test item was heated with the flame of a teclu burner. Glowing was observed during heating. No ignition occurred within two minutes.

Determination of Burning rate:

Not carried out as the test item showed no ignition.

Interpretation of results:

GHS criteria not met

Conclusions:

FAT 21015/C should be considered as not highly flammable.

Executive summary:

The flammability of the test substance was evaluated in a study conducted according to EU Method A.10. The substance did not ignite or propagate combustion when exposed to a burning flame along 200 mm of the powder train within the 2 minutes test period. Hence, FAT 21015/C should be considered as not highly flammable.

Description of key information

The flammability of the test substance was evaluated in a study conducted according to EU Method A.10.

Key value for chemical safety assessment

Flammability:

non flammable

Justification for classification or non-classification

Acid Yellow 079 is considered to be not highly flammable, hence it does not warrant classification according to the EU Classification, Labelling and Packaging of Substances and Mixtures (CLP) Regulation (EC) No. 1272/2008.
