Specific details on test material used for the study:

SOURCE OF TEST MATERIAL
- Source: Provided by sponsor
- Batch/Lot Number: 150701
- Expiration date of the lot/batch: 14 July 2017

STABILITY AND STORAGE CONDITIONS OF TEST MATERIAL
- Storage condition of test material: Controlled Room Temperature (15-25˚C), protected from humidity, under inert gas

Remarks on result:

no self ignition observed under the test conditions

During the three experiments no ignition observed. The temperature of the oven at which the sample temperature reaches 400 °C by self-heating was considered to be the self-ignition temperature.

Conclusions:

Under the conditions of the study, the test material has no relative self-ignition temperature based on the three replicate tests performed.

Executive summary:

The relative self-ignition temperature of the test material was investigated in accordance with the standardised guideline EU Method A.16 under GLP conditions.

The stainless still wire mesh cube was filled with the test material and tapped gently, adding more of the substance until the cube was completely full. The cube was then placed into the centre of the oven at room temperature. One thermocouple was placed at the centre of the cube while the other into the space between the cube and the wall of the oven. The temperature difference of the oven and sample were continuously recorded while the temperature of the oven was increased to the melting point at a rate of 0.5 °C/min. The experiment was repeated three times at 986 and 987 hPa atmospheric pressure.

Under the conditions of the study, the test material has no relative self-ignition temperature based on the three replicate tests performed.

Description of key information
