Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Autoignition temperature (corrected)*: 364 °C

* The corrected auto ignition temperature is calculated by subtracting 1.5% of the lowest experimentally observed auto ignition temperature (given in units of °C) in order to take into account all uncertainties (calibration, temperature measuring system, amount of substance, etc.). This value is then rounded to the next 1 K.

Electrical and non-electrical equipment, which may be in contact with explosive mixtures of the test substance and air, has to be of a temperature class T2 or higher.
