Remarks on result:

other: Definitive Test (minimum auto-ignition temperature) in triplicate. The lowest measured auto-ignition temperature was 343°C. This temperature was rounded down to the nearest 5°C according to DIN 51794.

Preliminary test

The estimated auto-ignition temperature was 361°C.

 

Main study

Ignition of the test substance shortly 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 < 10°C. According to the guidelines, no further testing was required. The lowest temperature at which ignition of the test substance occurred was 343°C. This temperature was rounded down to a multiple of 5°C and therefore given as the auto-ignition temperature of the test substance.

 

Table 1. Auto-ignition of the test item

Test	Volume [μl]	Auto-ignition temperature [°C]	Ignition delay [s]	Minimum auto-ignition temperature [°C]
1	70	352	3	345
	125	345	5
	175	348	4
2	100	352	8	343
	125	343	3
	200	359	2
3	75	354	4	346
	130	346	3
	175	360	4

The lowest measured auto-ignition temperature is 343°C, which was rounded down to the nearest 5°C, giving the auto-ignition temperature of 340°C.

Conclusions:

The auto-ignition temperature of the test item was determined to be 340°C at 1013.6 and 1014.5 hPa.

Executive summary:

The auto-ignition temperature was determined using EU Method A.15 under GLP. The auto-ignition temperature is the lowest temperature at which the test item will ignite when mixed with air under the conditions defined in the test method. Ignition of the test item within seconds 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 < 10°C. According to the guidelines, no further testing was required. The lowest temperature at which ignition of the test item occurred was 343°C. This temperature was rounded to the lowest multiple of 5°C and therefore 340°C was given as the auto-ignition temperature of the test item. Under the conditions of the study, the auto-ignition temperature was determined to be 340°C at 1013.6 and 1014.5 hPa.

Additional information

Key study : EU Method A.15, 2014 : The auto-ignition temperature was determined using EU Method A.15 under GLP. The auto-ignition temperature is the lowest temperature at which the test item will ignite when mixed with air under the conditions defined in the test method. Ignition of the test item within seconds 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 < 10°C. According to the guidelines, no further testing was required. The lowest temperature at which ignition of the test item occurred was 343°C. This temperature was rounded to the lowest multiple of 5°C and therefore 340°C was given as the auto-ignition temperature of the test item. Under the conditions of the study, the auto-ignition temperature was determined to be 340 °C at 1013.6 and 1014.5 hPa.
