Specific details on test material used for the study:

Identity: FAT 40819/A
Description: Red brown powder
Batch number: Red ROE 420 BOP 01/04
Purity: approx. 77 %
Stability of test item: Stable under storage condition
Expiry date: 02 November 2009
Stability of test item dilution: Stable in PEG 300 for at least 7 days at room temperature
Storage conditions: At room temperature.

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 appraisal of the molecular structure indicates that the molecule contains azo groups which might be associated with pyrophoric properties or the potential of evolving flammable gases in contact with water or humid air. Other chemicals groups associated with these properties are not present.

- Studies were performed in aqueous test systems (e.g. water solubility, surface tension, or hydrolysis behaviour). The test substance did not show any spontaneous ignition or formation of flammable gases performing the above mentioned studies. Thus, it can be concluded beyond reasonable doubt that the test item does not ignite spontaneously when in contact with water or humid air.

Interpretation of results:

GHS criteria not met

Conclusions:

According to EU method A10, the test substance is not considered to be highly flammable. Also, the test substance does not ignite spontaneously when in contact with water or humid air.

Executive summary:

In a GLP-compliant study, performed according to EU method A.10, the flammability of the test substance was determined. The flame of a gas burner was used as a ignition source. The test substance could not be ignited with a flame, but it started glowing. Therefore it could be concluded that the test substance is not highly flammable. Furthermore, it was concluded based on previous performed studies, that the test substance does not ignite spontaneously when in contact with water or humid air.

Description of key information

According to EU method A10, the test substance is not considered to be highly flammable. Also, the test substance does not ignite spontaneously when in contact with water or humid air.

Key value for chemical safety assessment

Flammability:

not classified

Additional information

In a GLP-compliant study, performed according to EU method A.10, the flammability of the test substance was determined (RCC 2005). The flame of a gas burner was used as a ignition source. The test substance could not be ignited with a flame, but it started glowing. Therefore, it could be concluded that the test substance is not highly flammable. Furthermore, it was concluded based on previous performed studies, that the test substance does not ignite spontaneously when in contact with water or humid air.

Justification for classification or non-classification

As the test substance is not flammable, classification is not needed according to the Directive 67/584/EEC and according to the EU Classification, Labelling and Packaging of Substances and Mixtures (CLP) Regulation (EC) No. 1272/2008.
