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

From the test results the temperature of the test material did not fluctuate. The test material is therefore not classified through Division 4.2 as hazardous for transportation.

Conclusions:
Under the conditions of this study the temperature of the test material did not fluctuate, therefore the test material is not a self-heating substance.
Executive summary:

The self-heating temperature of the test material was investigated in accordance with the UN Orange Book Test N.4: Test method for self-heating substances.

The test material was placed into a metal cube in an oven, the oven was heated to 140 °C, once at temperature the heating profiles of the test material and the oven were recorded for 24 hours.

Under the conditions of this study the temperature of the test material did not fluctuate, therefore the test material is not a self-heating substance.

Description of key information

Under the conditions of this study the temperature of the test material did not fluctuate, therefore the test material is not a self-heating substance.

Key value for chemical safety assessment
