Key result

Test procedure:

burning time (test type not further specified)

Remarks:

length of 250 mm

Burning time:

ca. 96 s

Remarks on result:

other: spread out of the combustion zone over a distance of 100 mm, after removal of the gas burner

The test substance was immediately inflammable by the hot flame of the gas burner. A spread out of the combustion zone over a distance of 100 mm in 96 seconds was observed after removal of the ignition flame.

Interpretation of results:

other: not highly flammable

Conclusions:

Under the conditions of the study, the test substance was classified as not highly flammable.

Executive summary:

A study was conducted to determine the flammability of the test substance, C12-16 ADBAC (purity: 94.4%) according to EU Method A.10, in compliance with GLP. The test was carried out by the ignition of a line with a length of 250 mm, a width of 20 mm and a height of 10 mm with the hot flame of a gas burner. The test substance was immediately inflammable by the hot flame of a gas burner. A spread out of the combustion zone over a distance of 100 mm in 96 seconds was observed after removal of the ignition flame. Under the conditions of the study, the test substance was classified as not highly flammable (Schulze, 2007).

Description of key information

The flammability was determined according to EU Method A.10 (Schulze, 2007)

Key value for chemical safety assessment

Flammability:

non flammable

Additional information

A study was conducted to determine the flammability of the test substance,C12-16 ADBAC (94.4% active) according to EU Method A.10, in compliance with GLP. The test was carried out by the ignition of a line with a length of 250 mm, a width of 20 mm and a height of 10 mm with the hot flame of a gas burner. The test substance was immediately inflammable by the hot flame of a gas burner. A spread out of the combustion zone over a distance of 100 mm in 96 seconds was observed after removal of the ignition flame. Under the conditions of the study, the test substance was classified as not highly flammable (Schulze, 2007).

Justification for classification or non-classification

Based on the results of the studies with the pure form and aqueous solutions, the test substance does not warrant a classification for flammability according to EU CLP criteria (Regulation EC 1272/2008).
