Key result

Auto-ignition temperature:

ca. 370 °C

Atm. press.:

>= 1 012 - <= 1 022 mBar

Conclusions:

The substance was evaluated for auto flammability in accordance with EU Method A.15 via a GLP-certified laboratory. The substance was determined to have an auto-ignition temperature of 370°C at 1012 - 1022 mbar.

Executive summary:

The substance was evaluated for auto flammability in accordance with EU Method A.15 via a GLP-certified laboratory.

A known mass of the substance was added to a heated open Erlenmeyer flask (200 mL) containing air. The contents of the flask were observed in a darkened room for five minutes following addition of a sample or until ignition occurred. Ignition was evidenced by the sudden appearance of a flame inside the flask. If a flame was not observed in five minutes, the amount of sample tested was considered non-flammable at the temperature of the test flask. If a flame was observed, the timer was stopped and the time interval between sample addition and the appearance of the flame recorded to the nearest second as the time-lag.

The test was repeated at different temperatures and with differing sample masses until the minimum ignition temperature was obtained at any mass. The temperature was reduced by 2°C and six replicate tests conducted using the amount at which the lowest ignition temperature was found.

The lowest flask temperature at which ignition occurred was taken as the auto-ignition temperature. The substance was determined to have an auto-ignition temperature of 370°C at 1012 - 1022 mbar.
