Key result

Auto-ignition temperature:

365 °C

Atm. press.:

1 013.25 hPa

Conclusions:

The auto-ignition temperature of the formulation product was determined to be 365 °C.

Executive summary:

The auto-ignition temperature of the formulation product was determined according to DIN 51794. It was determined to be 365 °C.

Description of key information

The test item is a solid with melting point below 160 °C, therefore, no study on self-ignition is required. The auto-ignition temperature of the liquid formulation product was additionally determined to be 365 °C.

Key value for chemical safety assessment

Autoflammability / Self-ignition temperature at 101 325 Pa:

365 °C

Additional information

In accordance with column 2 of REACH Annex VII, the auto flammability study does not need to be conducted as the substance is a solid with a melting point <160 °C.

Additionally, the auto-ignition temperature of the liquid formulation product was determined according to DIN 51794. It was determined to be 365 °C.
