- Executive summary:
The test item vinylcyclohexane has an auto-ignition temperature of 255 °C according to the Regulation EC No. 440/2008 Method A.15. Auto-Ignition Temperature (Liquids and Gases) and DIN 51794 (2003): Determination of Ignition Temperature.
It is noted here that according to ECHA guidance – Guidance on information requirements and chemical safety assessment; chapter R.7A: Endpoint specific guidance, October 2015 – the auto-ignition temperature for liquids is not used directly for classification and labelling according to Regulation (EC) 1272/2008. However, it can be used in the chemical safety assessment in considering risks associated with processing the substance.
According to DIN EN 13463-1 the test item has to be assigned to temperature class T3 (see the following Table).

Results
Preliminary Test
An approximate value of the ignition temperature of the test item was first determined by a preliminary test. The Table below gives 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.

Based on results of the main test series, the lowest auto-ignition temperature was 257 °C.
Regulation EC No. 440/2008 and DIN 51794: The auto-ignition temperature rounded down to the nearest multiple of 5 °C was determined as 255 °C.
For information:
DIN EN 14522: The auto-ignition temperature reduced by 1.5 % and rounded to the nearest integer temperature was determined as 253 °C.
