Reference
Endpoint:
flammable solids
Type of information:
experimental study
Adequacy of study:
key study
Study period:
28 Sept 1998 to 14 Dec 1998
Reliability:
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
guideline study
Qualifier:
according to guideline
Guideline:
EU Method A.10 (Flammability (Solids))
Deviations:
not specified
GLP compliance:
yes (incl. QA statement)
Specific details on test material used for the study:
SOURCE OF TEST MATERIAL
- Source and lot/batch No.of test material: TVR 50
- Expiration date of the lot/batch: September 01, 2004

STABILITY AND STORAGE CONDITIONS OF TEST MATERIAL
- Storage condition of test material: At room temperature at about 20 °C.
Test procedure:
burning rate test: preliminary screening test
Remarks:
FAT 40'571/A could not be ignited with a flame during the pretest (contact time of about 2 minutes). Therefore, no main test was performed
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

FAT 40'571/A could not be ignited with a flame during the pretest (contact time of about 2 minutes). In contact with the ignition source, the flame of the gas burner became yellow and FAT 40'571/A carbonized. The remaining test item was coloured black and not melted. A slightly sticky, crumbling residue remained. Therefore, no main test was performed.

In conclusion, FAT 40'571/A is not "highly flammable" according to the criteria of the guideline.

Interpretation of results:
GHS criteria not met
Conclusions:
FAT 40571/A is not highly flammable.
Executive summary:

The determination of the flammability of the FAT 40571/A was performed in accordance with the EU A. 10. The test substance could not be ignited with a flame during the pretest (contact time of about 2 minutes). In contact with the ignition source, the flame of the gas burner became yellow and FAT 40'571/A carbonized. The remaining test item was coloured black and not melted. A slightly sticky, crumbling residue remained. Therefore, no main test was performed.

In conclusion, FAT 40'571/A is not "highly flammable" according to the criteria of the guideline.

Description of key information

Reactive Brown 49 is not highly flammable.

Key value for chemical safety assessment

Flammability:
not classified

Additional information

The determination of the flammability of the FAT 40571/A was performed in accordance with the EU A. 10. The test substance could not be ignited with a flame during the pretest (contact time of about 2 minutes). In contact with the ignition source, the flame of the gas burner became yellow and Reactive Brown 49 carbonized. The remaining test item was coloured black and not melted. A slightly sticky, crumbling residue remained. Therefore, no main test was performed.


 


In conclusion, REactive Black 49 is not "highly flammable" according to the criteria of the guideline.

Justification for classification or non-classification

As the Reactive Brown 49 is considered to be not flammable, classification is not needed according to the EU Classification, Labelling and Packaging of Substances and Mixtures (CLP) Regulation (EC) No. 1272/2008.
