- Executive summary:
A study was conducted to determine the auto-ignition temperature of the substance according to the ASTM Method E659. A 500 mL glass flask, covered with aluminum foil, is suspended in a temperature controlled oven. One thermocouple is inserted into the vapor space on the flask, and three are secured to the outside of the flask at different locations. The thermocouples are connected to a computer that displays and records the temperatures.The flask is heated to a constant initial temperature (typically 300°C) and a 0.1mL sample (0.1 g for solids) is injected into the flask. The procedure is repeated, until increasing the amount of sample no longer results in a lower ignition temperature. Additional trials are then run around the optimum sample loading, using smaller temperature steps to define the minimum ignition temperature within 3°C. The minimum ignition temperature is reported as the auto-ignition temperature. Under the study conditions, the auto-ignition temperature of the substance was determined to be in the range 410°C - 415°C (Leclercq, 2015).

Additional information
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation).
