Key result
Remarks on result:
no self ignition observed under the test conditions

The edge length of the cubic sample container was 100 mm. The internal temperature in the oven was recorded at 140 °C (corrected value). The temperature of the test material was recorded between 139 and 140 °C (corrected values).

At the start of the test, the test material was a white powder and it remained a white powder after the test.

Conclusions:
Under the conditions of the test no self-ignition of the test material was recorded and the temperature of the sample did not exceed the oven temperature by 60 °C. The result is considered negative.
Executive summary:

The self ignition of the test material was investigated in a study which was conducted in accordance with the standardised guideline UN Method N.4 under GLP conditions.

The edge length of the cubic sample container was 100 mm. The internal temperature in the oven was recorded at 140 °C (corrected value). The temperature of the test material was recorded between 139 and 140 °C (corrected values).

At the start of the test, the test material was a white powder and it remained a white powder after the test.

Under the conditions of the test no self-ignition of the test material was recorded and the temperature of the sample did not exceed the oven temperature by 60 °C. The result is considered negative.

Description of key information

Key value for chemical safety assessment

Additional information

The self ignition of the test material was investigated in a study which was conducted in accordance with the standardised guideline UN Method N.4 under GLP conditions. The study was awarded a reliability score of 1 in accordance with the criteria set forth by Klimisch et al. (1997).

The edge length of the cubic sample container was 100 mm. The internal temperature in the oven was recorded at 140 °C (corrected value). The temperature of the test material was recorded between 139 and 140 °C (corrected values).

At the start of the test, the test material was a white powder and it remained a white powder after the test.

Under the conditions of the test no self-ignition of the test material was recorded and the temperature of the sample did not exceed the oven temperature by 60 °C. The result is considered negative.
