Key result

Auto-ignition temperature:

ca. 380 °C

Atm. press.:

> 987 - < 1 036 hPa

PRELIMINARY TEST:

The estimated auto-ignition temperature was 400 °C.

 

MAIN STUDY:

Ignition of the test substance within 5 minutes after introduction was observed with each sample volume and with each test a minimum auto-ignition temperature was obtained. The maximum deviation between the three values was <20 °C. According to the guidelines, no further testing was required.

The lowest temperature at which ignition of the test substance occurred was 383 °C. This temperature was rounded off to the nearest multiple of 5 °C giving an auto-ignition temperature of the test substance of 380 °C.

Test	Volume     [µL]	Auto-ignition temperature   [°C]	Ignition delay     [s]	Colour of the flame	Minimum auto-ignition temperature [°C]
1	70	400	4	orange/blue	383
	100	383	7	orange/blue
	120	388	5	orange/blue
2	140	398	3	orange/blue	391
	190	391	5	orange/blue
	225	400	4	orange/blue
3	150	405	4	orange/blue	393
	175	393	4	orange/blue
	300	406	3	orange/blue

Conclusions:

The substance has an auto-ignition temperature of 380 °C at 986.8 - 1035.9 hPa.

Executive summary:

The auto-ignition of the test substance was determined in a study in accordance with EU Method A.15 and in compliance with GLP criteria. In this study, the auto-ignition temperature was determined in three tests with varying test volumes (test 1: 70 - 120 µL; test 2: 140 - 225 µL and test 3: 150 - 300 µL). Ignition of the test substance within 5 minutes after introduction was observed with each sample volume. The lowest temperature at which ignition of the test substance occurred was 383 °C. This temperature was rounded off to the nearest multiple of 5 °C giving an auto-ignition temperature of the test substance of 380 °C.

Additional information

The auto-ignition of the test substance was determined in a study in accordance with EU Method A.15 and in compliance with GLP criteria. In this study, the auto-ignition temperature was determined in three tests with varying test volumes (test 1: 70 - 120 µL; test 2: 140 - 225 µL and test 3: 150 - 300 µL). Ignition of the test substance within 5 minutes after introduction was observed with each sample volume. The lowest temperature at which ignition of the test substance occurred was 383°C. This temperature was rounded off to the nearest multiple of 5 °C giving an auto-ignition temperature of the test substance of 380 °C.
