Main Study

The results of the main study on the determination of the auto-ignition temperature of the test item are given in the table below:

Test	Volume	Auto-ignition	Ignition delay	Colour of the flame	Minimum auto-ignition
		temperature			temperature
					[°C]
	[μL]	[°C]	[s]
1	70	488	15	orange/blue	485
	150	485	17	orange/blue
	250	486	12	orange/blue
2	50	490	11	orange/blue	483
	135	483	16	orange/blue
	300	486	10	orange/blue
3	40	498	11	orange/blue	485
	140	485	15	orange/blue
	340	490	10	orange/blue

Ignition of the test item 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 item occurred was 483°C. This temperature was rounded down to the nearest multiple of 5°C giving an auto-ignition temperature of the test item of 480°C.

Conclusions:

Commercially available auto-ignition temperature apparatus was used for the determination of the degree of auto-ignitability of the test item.
The test item is auto-ignitable with an auto-ignition temperature of 480°C.
The atmospheric pressure was 1030 hPa.

Executive summary:

Information	Guideline(s)	Result	Comment
Auto-ignition temperature	EC A.15	480°C	at 1030 hPa
	DIN 51794
