Endpoint:

flammable solids

Type of information:

experimental study

Adequacy of study:

key study

Study period:

Experiment start and date - 06 March 2003; Study completion date - 22 April 2003.

Reliability:

1 (reliable without restriction)

Rationale for reliability incl. deficiencies:

guideline study

Qualifier:

according to guideline

Guideline:

EU Method A.10 (Flammability (Solids))

Deviations:

no

GLP compliance:

yes (incl. QA statement)

Specific details on test material used for the study:

Identity: FAT 40810/A
Batch: WP 6/02
Purity: approx 75%
Appearance: Solid, dark brownish powder
Expiration date: 12 December 2010
Storage: At room temperature at about 20 °C

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

In contact with the ignition source, FAT 40'810/A was glowing and carbonized on the surface. The flame changed its color to orange and white fume was observed. The surface became carbonized but underneath the test item remained unchanged. Therefore, no main test was performed.

The tests A.12 and A.13 were not conducted as negative results would be expected in view of experience in use. The substance is stable at room temperature and does not evolve any flammable gases in contact with water or humid air.

Interpretation of results:

GHS criteria not met

Conclusions:

FAT 40'810/A is non flammable under the conditions of this test, as it could not be ignited with a bunsen burner.

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.

FAT 40’810/A could not be ignited with a flame during the preliminary test (contact time of about 2 minutes). in contact with the ignition source, FAT 40’810/A was glowing and carbonized on the surface.

The flame of the gas burner changed its color to orange and white fume was observed. Underneath the carbonized surface the test item remained unchanged (i.e. reddish to brown powder). Therefore, no main test was performed. in conclusion, FAT 40’810/A is not "highly flammable" according to the criteria of the guideline.

Key value for chemical safety assessment

Flammability:

not classified

Justification for classification or non-classification

Based on results from a flammability test and experience in handling and use, FAT40810/A is neither flammable nor pyrophoric nor is it reacting with water forming flammable gases. Thus, classification for flammability according to CLP (Regulation EC No 1272/2008) or DSD (Directive 67/548/EEC) for flammability or pyrophoricity is not required.
