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

The test item turned into milky white liquid when the flame was applied. No continuous combustion or smoulder phenomena were observed after removal of the flame.

Interpretation of results:

not classified based on GHS criteria

Conclusions:

Based on the testing results, the test item is considered not highly flammable according to EEC Dir 92/69 Part A, A.10.

Executive summary:

The flammability of test item was tested according to EEC A.10. The test substance pile was ignited for 2 minutes applying a flame as ignition source in the preliminary test.

The test item turned into milky white liquid when the flame was applied. No continuous combustion or smoulder phenomena were observed after removal the flame. Based on the testing results, test item is considered not highly flammable according to EEC Dir 92/69 Part A, A.10.

Description of key information

Flammability:

The test substance pile was ignited for 2 minutes applying a flame as ignition source in the preliminary test. The test item turned into milky white liquid when the flame was applied. Nocontinuous combustion or smoulder phenomena were observed after removal the flame.

Pyrophoric solids:

The study does not need to be conducted because the substance is known to be stable in contact with air at room temperature for prolonged periods of time (days) and hence, the classification procedure does not need to be applied.

Flammability in contact with water:

The study does not need to be conducted because the organic substance does not contain metals or metalloids and hence, the classification procedure does not need to be applied.

Key value for chemical safety assessment

Flammability:

not classified

Justification for classification or non-classification

Flammable solids:

This substance does not ignite and propagate combustion by burning with flame within the 2 minutes test period.

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

Pyrophoric solids:

In accordance with Regulation (EC) No. 1272/2008 section 2.10.4.1, the classification procedure for pyrophoric solids need not be applied when experience in manufacture or handling shows that the substance or mixture does not ignite spontaneously on coming into contact with air at normal temperatures (i.e. the substance is known to be stable at room temperature for prolonged periods of time (days)). As experience show this substance does not ignite spontaneously on coming into contact

with air at normal temperature, so the classification procedure for pyrophoric solids need not be applied for this substance.

Substances and mixtures which in contact with water emit flammable gases:

In accordance with Regulation (EC) No. 1272/2008 section 2.12.4.1(a), the classification procedure for this class need not be applied if the chemical structure of the substance or mixture does not contain metals or metalloids. As no metals or metalloids present in the molecule of this substance, so the classification procedure for this class need not be applied for this substance.
