Key result
Sample tested:
test mixture as specified
Remarks:
10% test substance with cellulose
Parameter:
maximum burning rate
Result:
0.67 mm/s

The mixture containing 10 % of the test substance burnt (flamed) all distance of the pile. The reaction zone of other mixtures did not propagate over an initial distance of 30 mm, no burning was observed. Burning rate of none test substance mixture with cellulose was higher than reference mixture burning rate (60:40, w/w).

Interpretation of results:
GHS criteria not met
Conclusions:
Based on results obtained from train test, it is obvious that test substance, Direct Brown 103, shouldn´t be considered as a substance with oxidizing properties.
Executive summary:

The oxidizing properties of test substance, Direct Brown 103, were determined.

The procedure was performed according to the Method A.17 Oxidizing properties (Solids), Council Regulation (EC) No.440/2008, published in O.J. L 142, 2008.

Based on the result obtained from train test, it is obvious that none of the test substance, Direct Brown 103, shouldn´t be considered as a substance with oxidizing properties.

Description of key information

The test substance, Direct Brown 103, shouldn´t be considered as a substance with oxidizing properties.

Key value for chemical safety assessment

Oxidising properties:
