Specific details on test material used for the study:

Identity: FAT 40825/A
Batch number: CHU 297 / BOP 04/05
Purity: Organic part (Na-salt): approx. 83.7 %; All coloured components: approx. 80.54 %; Main component: approx. 59.1 %.
Appearance: Solid, black powder
Storage conditions: At room temperature at about 20 °C
Expiration date: December 31, 2010

Test procedure:

burning rate test: preliminary screening test

Remarks:

or specified in description of method (migrated information)

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

Remarks:

In contact with the ignition source, FAT 40825/A started glowing while the flame became orange. The surface slightly swelled up. The test item sustained glowing for about 2 minutes but glowing did not expand. FAT 40825/A could not be ignited with a flame during the preliminary test (contact time of about 2 minutes).

Interpretation of results:

GHS criteria not met

Conclusions:

FAT 40825/A could not be ignited with a flame during the preliminary test (contact time of about 2 minutes), as the material did not sustain a propagating flame.

Executive summary:

The determination of the flammability of the test item was performed in accordance with the EEC Directive 92/69, Part A, Methods for the determination of physico-chemical properties, A. 10 "Flammability (solids)", EEC Publication No. L383, December 1992. An attempt was made to ignite the sample (see section 2.3.1) with the aim to determine the burning time over a distance of 200 mm, if applicable. The flame of a gas burner was used as ignition source. The test was conducted in a fume cupboard with constant air speed. Additionally, a draught screen was erected around the apparatus. In contact with the ignition source, FAT 40825/A started glowing while the flame became orange. The surface slightly swelled up. The test item sustained glowing for about 2 minutes but glowing did not expand. FAT 40825/A could not be ignited with a flame during the preliminary test (contact time of about 2 minutes). Therefore, no main test was performed.

Additional information

The determination of the flammability of the test item was performed in accordance with the EEC Directive 92/69, Part A, Methods for the determination of physico-chemical properties, A. 10 "Flammability (solids)", EEC Publication No. L383, December 1992. In contact with the ignition source, FAT 40825/A started glowing while the flame became orange. The surface slightly swelled up. The test item sustained glowing for about 2 minutes but glowing did not expand. FAT 40825/A could not be ignited with a flame during the preliminary test (contact time of about 2 minutes). Therefore, no main test was performed.

Justification for classification or non-classification

Based on the results from the test for flammability of solids, in which the substance did not maintain a flame, and experience in handling and use, showing that the substance is neither emitting flammable gases (see test on water solubility) nor is pyrophoric, the substance is not classifiable for flammability according to CLP (Regulation EC No 1272/2008).
