Description of key information
Whilst heating the test item, no relevant exothermic reaction /self-heating of the sample has been observed. On completion of the test, the test item was a shrunken black charred mass.
The test item has been determined to not have a relative self-ignition temperature below 400 °C.
Key value for chemical safety assessment
Additional information
The determination was carried out using a procedure designed to be compatible with Method A.16 Relative Self-Ignition Temperature for Solids of Commission Regulation (EC) No 440/2008 of 30 May 2008.
The cube was completely filled with the test item and placed in the center of the oven at room temperature. A thermocouple was placed in the center 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/min. The temperature/time curves relating to the condition in the centre of the sample and the oven were recorded on a data logger. Before and after the test the appearance of the test item was recorded.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
