Applicant's summary and conclusion

Conclusions:
The final auto-ignition temperature of 236°C was obtained.
Executive summary:

A study was performed to determine the auto-ignition Temperature of the test item Triisononylamine. The method followed was designed to be compliant with the Council Regulation (EC) No 440/2008, Method A.15: “Auto-ignition Temperature (Liquids and gases)” and was conducted according to GLP. 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 five auto-ignition temperature were recorded: 240°C, 281°C, 275°C, 285°C and 265°C.

The lowest value (240°C) was 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 236°C was obtained.

The atmospheric pressure was 979.0 hPa at the beginning of the test and 976.0 hPa at the end of the test.
