Key result
Test procedure:
burning rate test: preliminary screening test
Burning time:
2 min
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

The test item turned from white solid powder to black block solid when the flame was applied. No continuous combustion or smoulder phenomena were observed after removal the flame.

Interpretation of results:
not classified based on GHS criteria
Conclusions:
The test substance was considered not highly flammable.
Executive summary:

The flammability of the test substance was conducted according to EU Method A.10 (Flammability (Solids)).

The test substance pile was ignited for 2 minutes applying a flame as ignition source in the preliminary test.

The test item turned from white solid powder to black block solid when the flame was applied. No continuous combustion or smoulder phenomena were observed after removal the flame.

The test substance was considered not highly flammable.

Description of key information

Key value for chemical safety assessment

Flammability:
not classified

Additional information

The flammability of the test substance was conducted according to EU Method A.10 (Flammability (Solids)).

The test substance pile was ignited for 2 minutes applying a flame as ignition source in the preliminary test.

The test item turned from white solid powder to black block solid when the flame was applied. No continuous combustion or smoulder phenomena were observed after removal the flame.

The test substance was considered not highly flammable.

Justification for classification or non-classification

The test substance pile was ignited for 2 minutes applying a flame as ignition source, and no continuous combustion or smoulder phenomena were observed after removal of the flame in the preliminary test.

In accordance with Regulation (EC) No. 1272/2008 section 2.7.2.1, the substance should not be classified as flammability solids.
