Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Interpretation of Results
As determined by this method, the AIT is the lowest temperature at which the substance will produce hot flame ignition in air at atmospheric pressure without the aid of an external
ignition source such as spark or flame. lt is the lowest temperature to which a combustible mixture must be raised so that the rate of heat evolved by the exothermic oxidation reaction
will exceed the rate at which heat is lost to the surroundings and cause ignition. Autoignition, by its very nature, is dependent on the chemical and physical properties of the material and
the method and apparatus employed for its determination. The autoignition temperature by a given method does not necessarily represent the minimum temperature at which a given
material will seif ignite. The volume of the vessel used is particularly important since lower autoignition temperatures will be achieved in larger vessels.
The autoignition temperature of the substance has been determined to be 326°C
Hot flame autoignition temperature (AIT, °C): 326
lncluding correction factor for barometric pressure (°C): 326
Time lag to autoignition (s): 9
Barometrie pressure (kPa): 102.5
Sample quantity (μI): 500
Comments: The sample ignited with an orange flame.
Description of key information
The auto-ignition temperature of the substance is determined to be 326 °C at 102.5 kPa.
Key value for chemical safety assessment
- Autoflammability / Self-ignition temperature at 101 325 Pa:
- 326 °C
Additional information
Two GLP studies were conducted according to Regulation (EC) No 44012008, Annex A.l5.
Siemens GLP study 20140408.01 determined the auto-ignition temperature to be 355 °C at 1013.25 hPa and BASF GLP study SIK-no. 15/1136 determined the auto-ignition temperature to be 326 °C at 102.5.kPa.
The value of the recent study (SIK-no.15/1136) was chosen as key value.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
