Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Key result
Remarks on result:
no self ignition observed under the test conditions

The sample entered a long shallow endotherm before rising up at 163°C into a very sharp exothermic reaction in which the sample temperature reaches a maximum of approx 325°C.

On completion of testing no visible sample remained. As the test material was consumed, it is most probable that this occurred during the exothermic event.

Under the conditions of the test no self-ignition of NMMO was observed.
Executive summary:

The self-ignition of the test item was determined according to EU Method A.16. Under the conditions of the test no self-ignition of NMMO was observed.

Description of key information

NMMO was concluded not to be auto flammable under the conditions of the EC A.16 test performed under GLP conditions (Younis 2012).

Key value for chemical safety assessment

Additional information

Value used for CSA: no self-ignition observed

At 163°C a sharp exothermic reaction was observed in which the sample temperature reached a maximum of approx 325°C.
