Conclusions:
The auto-ignition temperature of the substance was determined to be 295°C at 1033.1-1038.0 hPa.
Executive summary:

The auto-ignition temperature of the substance was determined to be 295°C at 1033.1-1038.0 hPa. The test was performed in accordance with EC A.15, DIN 51794 and IEC 79-4 and according to the principles of GLP.

Description of key information

The auto-ignition temperature of the substance was determined to be 295°C at 1033.1-1038.0 hPa.

MPKO, the hydrolysis product of OS2600, is auto-ignitable with an auto-ignition temperature at 1003.0 - 1012.5 hPa of 325°C.

Key value for chemical safety assessment

Autoflammability / Self-ignition temperature at 101 325 Pa:
