Reference
Endpoint:
flammable solids
Type of information:
experimental study
Adequacy of study:
key study
Study period:
Experiment start and end date - 16 April 1999; Study completion date - 28 April 1999.
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
Specific details on test material used for the study:
Identity: FAT 40'574/B
Batch: WP 23/99
Purity: Approx. 75 %
Appearance: Solid, dark-red powder
Storage: At room temperature at about 20 °C
Expiration Date: 08 February 2006
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 substance could not be ignited with a flame. In contact with the ignition source, a bright orange flame was observed. The test substance carbonized and became brittle. Therefore, no main test was performed.

Interpretation of results:
GHS criteria not met
Conclusions:
The substance is not considered to be flammable.
Executive summary:

The determination of the flammability of the test item was performed in accordance with the EEC Directive 92/69, Methods for the determination of physico-chemical properties, A. 10 "Flammability (solids)", EEC Publication No. L383, December 1992. FAT 40574/B could not be ignited with a flame during the pretest (contact time of about 2 minutes). In contact with the ignition source, a bright, orange flame was observed which evolved no smoke or soot. FAT 40574/B carbonized and became brittle. Therefore, no main test was performed. In conclusion, FAT 40574/B is not "highly flammable" according to the criteria of the guideline.
