Description of key information

Relative self-ignition temperature > 400 °C, EU Method A.16, Tremain (2007).

Key value for chemical safety assessment

Additional information

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

During the study a stainless steel mesh cube (approximately 20 x 20 x 20 mm) was filled with test material and suspended in an oven. A thermocouple was placed in the centre of the sample and another in the oven. The oven temperature was programmed to increase from ambient to 400 °C at a rate of 0.5 °C per minute. The temperature / time curves relating to the condition in the centre of the sample and the oven were recorded on a two channel chart recorder.

At the end of the test, the cube contained grey charred remains. Under the conditions of this study, the test material was found not to have a relative self-ignition temperature below 400 °C.
