Experiment start and end date - 14 April 2010; Study completion date - 31 May 2010.

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:

Identification: FAT 40851/A TE
Batch Number: TZ 5891 / BOP 02-09
Purity: 69.9 % all coloured components
Appearance: Orange powder
Expiry Date: July 31, 2014
Storage Conditions: 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

Flammability

In contact with the ignition source, the surface of test substance gleamed and became black. The color of the gas flame changed to orange. Underneath the carbonized surface, unchanged test item remained. The test substance could not be ignited with a flame during the preliminary test (contact time of about 2 minutes). Therefore, no main test was performed.

 

Flammability in Contact with Water and Pyrophoric Properties (non-GLP):

Chemical Structure:

The appraisal of the molecular structure indicates no risk with respect to pyrophoric properties or the potential of evolving flammable gases in contact with water or humid air.

 

Practical Experience:

Studies were performed in aqueous test systems (e.g. water solubility). The test item did not show any spontaneous ignition or formation of flammable gases performing the abovementioned study.

Interpretation of results:

GHS criteria not met

Conclusions:

Based on the results of this study, test substance is not "highly flammable" according to the criteria of the guideline. test substance does not ignite spontaneously when in contact with water or humid air and shows no risk with respect to pyrophoric properties.

Executive summary:

The determination of the flammability of the test item was performed under GLP in accordance with the EEC Directive 92/69, EEC Publication No. L383, December 1992 and Council Regulation (EC) No. 440/2008, 30 May 2008, Part A, Methods for the determination of physico-chemical properties, A. 10 “Flammability (solids)”. In contact with the ignition source, the surface of test substance gleamed and became black. The color of the gas flame changed to orange. Underneath the carbonized surface, unchanged test item remained. test substance could not be ignited with a flame during the preliminary test (contact time of about 2 minutes). Therefore, no main test was performed. Based on the results of this study, test substance is not "highly flammable" according to the criteria of the guideline. Additionally the Flammability in Contact with Water and Pyrophoric Properties was assessed. The assessment was performed based on the chemical structure and the test item properties. This assessment is not subject of the GLP requirements and therefore excluded from the statement of compliance. The appraisal of the molecular structure indicates no risk with respect to pyrophoric properties or the potential of evolving flammable gases in contact with water or humid air. Further evidence is given by practical experience. Studies were performed in aqueous test systems (e.g. water solubility). The test item did not show any spontaneous ignition or formation of flammable gases performing the above-mentioned study. In conclusion it can be assessed that test substance does not ignite spontaneously when in contact with water or humid air and shows no risk with respect to pyrophoric properties.

Justification for classification or non-classification

FAT 40851/A could not be ignited in a standard flammability test for solid substances. In addition, the substance neither does spontaneously ignite in contact with water or humid air nor does it release ignitable gases. Hence, FAT 40851/A does not require classification for flammability.
