Specific details on test material used for the study:

SOURCE OF TEST MATERIAL
- Source and lot/batch number of test material: SI/May2020/CR/001(India)

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

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.

Interpretation of results:

GHS criteria not met

Conclusions:

FAT 20044/C should be considered as not highly flammable.

Executive summary:

Determination of the Flammability with FAT 20044/C was carried out according EU method A.10. In 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. While, in 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. Based on the study results, no ignition was observed throughout the course of the test, so FAT 20044/C should be considered as not highly flammable.

Key value for chemical safety assessment

Flammability:

not classified

Justification for classification or non-classification

The test substance 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.
