Preliminary Test

An approximate value of the ignition temperature of the test item was firstly determined by the preliminary test. Table 1gives the result of the preliminary test. An ignition is denoted as "+" and no ignition is denoted as "-". 5 drops were put into the Erlenmeyer flask at each temperature.

 

Table 1: Results of the preliminary test

	Preliminary test
Temperature / °C	400	416	423
Ignition / +/-	-	-	+
	Atmospheric pressure:		995.2 hPa

 

In the preliminary test, the lowest temperature at which an ignition occurred was 423 °C.

Main Test

The results of the main test are given in the following Tables 2 and 3. An ignition is denoted as "+" and no ignition is denoted as "-".

According to observations in the main test series, the auto-ignition temperature rounded down with an accuracy of 5 °C was determined to be 410 °C.

Although the auto-ignition temperature for liquids is not used directly for classification and labeling according to regulation (EC) 1272/2008, according to DIN EN 13463-1 the test item has to be assigned to temperature class T2 (see the following Table 5).

Temperature class	Maximum surface temperature / minimum auto ignition temperature[°C]
T1	450
T2	300
T3	200
T4	135
T5	100
T6	85
