- Executive summary:
A study was performed to determine the auto-ignition Temperature of the test item N,N-dimethyl dodec-9-enamide. The method followed was designed to be compliant with the Commission Regulation (EC) No 440/2008, Method A.15: “Auto-ignition Temperature (Liquids and gases)”.
In this method, the auto-ignition temperature of the test item was determined by varying the temperature of the test vessel and the amount of test substance.
The lowest temperature where ignition occurs was retained and, in order to take into account all uncertainties (calibration, temperature measuring system, amount of substance etc.), this lowest value was reduced by the absolute deviation calculated using the reproducibility value (1.5% relative) as described in DIN EN 14522:2005.
Two trials were conducted. In the first one, the preselected auto-ignition temperature was set to 150°C but no ignition occurred and the test stopped automatically. In the second one, the preselected auto-ignition temperature was set to 350°C and three auto-ignition temperature were recorded (recorded as LASTIP on raw data): 245°C, 247°C and 247°C. During this trial, the measurement was relaunched once after replacement of the Viton tube by an Acetone-resistant tube because of compatibility issue between the tube and the test item. It was relaunched a second time due to a breakdown of the heating oven.
As the three auto-ignition temperatures obtained with the determination program did not differ by more than 2% from the mean, the results were validated and the lowest value (245°C) was automatically reduced by the absolute deviation calculated using the reproducibility value (1.5% relative) as described in DIN EN 14522:2005.
This value was rounded to the nearest 1 °C and a final auto-ignition temperature of 241°C was obtained.
The atmospheric pressure was 974 hPa at the beginning of the test (979 hPa after repair of the oven) and 984 hPa at the end of the test.
The final auto-ignition temperature was determined to be 241°C.
Reference
Apparatus control
The apparatus control was performed on 17/12/2021 with acetone (purity of 99.96%) and on 15/12/2021 with n-heptane (purity over 99.3%). VORB program was used.
Each substance owns a specific starting temperature and a measured lowest temperature for ignition that are listed below:
Reference substance |

*: Reference values according to DIN EN 14522:2005
The apparatus control was validated as the lowest auto-ignition temperature measured for each reference substance did not differ by more than 1.5% from the reference value.
