Key result

Auto-ignition temperature:

395 °C

Atm. press.:

> 1 006.7 - < 1 019.2 hPa

Remarks on result:

other: The lowest temperature at which ignition of the test substance occurred was 398°C. This temperature was rounded down to the nearest multiple of 5°C giving the auto-ignition temperature of the test substance.

Conclusions:

The auto-ignition temperature of the substance was determined to be 395°C at 1006.7 -1019.2 hPa using a commercially available auto-ignition temperature apparatus (in accordance with EC A.15, DIN 51794 and IEC 79-4 and in compliance with GLP).

Description of key information

The auto-ignition temperature of the substance

was determined to be 395°C at 1006.7 -1019.2 hPa

using a commercially available auto-ignition

temperature apparatus (in accordance

with EC A.15, DIN 51794 and IEC 79-4

and in compliance with GLP).

Key value for chemical safety assessment

Autoflammability / Self-ignition temperature at 101 325 Pa:

395 °C

Additional information

Because the auto-ignition temperature of the test substance, at 101325 Pa, has been determined to be 395 °C, the test substance is not to be classified for self-heating substances and mixtures, according to the CLP regulation.
