Portions of the test item were brought in by means of a syringe. Therefore, the test item had to be heated to approx. 70°C. The time-lag between application and ignition was measured for all tests. After each application of the test item, the test vessel was flushed completely with clean air to be sure to have a clean test vessel after each test. After flushing, a sufficient interval of time was allowed to ensure that the flask temperature is stabilised at the desired test temperature before the next sample was brought in.

In test 1, starting at 300 °C, the temperature was decreased in steps of 5 °C. If no ignition took place any more, although the amount of the injected test item was increased to a maximum of 20 drops, the trials were continued at a temperature 2 °C below the last positive ignition trial. Before the performance of test 2 (starting at 270°C) and test 3 (starting at 260 °C) a new test vessel was used to avoid contamination and systematic errors. The procedure of both tests was similar to test 1.

Test 1	Temperature [°C]	Injected volume [Drops]	Time-lag [s] until ignition
	300	5	7
	295	5	9
	290	5	12
	285	5 / 10	- / 24
	280	10	20
	275	10	23
	270	10 / 15	- / 23
	265	15	76
	260	15 / 20	- / 47
	255	20	-
	258	20	53
	256	20	-

Test 2	Temperature [°C]	Injected volume [Drops]	Time-lag [s] until ignition
	270	5 / 10	- / 21
	265	10 / 15	- / 34
	260	15	33
	255	15 / 20	- / 56
	250	20	98
	245	20	-
	248	20	-

Test 3	Temperature [°C]	Injected volume [Drops]	Time-lag [s] until ignition
	260	5 / 10	- / 42
	255	10 / 15 / 20	- / - / 66
	250	20	92
	245	20	-
	248	20	-

The measured lowest ignition temperatures of the main test are < 300 °C and do not differ by more than 10 °C, thus the test is satisfactory.

The auto-ignition temperature is defined as the lowest temperature of all single results of the main test, but rounded to multiples of 5 °C.

	Test 1	Test 2	Test 3
Lowest ignition temperatures [°C]	258	250	250
Auto-ignition temperature [°C]	250

Conclusions:

Auto-ignition temperature (1002 hPa): 250 °C.

Executive summary:

The auto-ignition temperature of the test item was determined according to EU test method A.15 [Directive 92/69/EEC, Official Journal L 383 A 1992] and DIN 51 794.

Auto-ignition temperature (1002 hPa): 250 °C.

Description of key information

The auto-ignition temperature of the test item was determined according to EU test method A.15 [Directive 92/69/EEC, Official Journal L 383 A 1992] and DIN 51 794.

Based on the result of three tests the auto-ignition temperature is determined to be 250 °C at 1002 hPa.
