Materials and methods
Test guideline
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.15 (Auto-Ignition Temperature (Liquids and Gases))
- Version / remarks:
- 30 May 2008
- Deviations:
- yes
- Remarks:
- see below: Principles of method if other than guideline
- Principles of method if other than guideline:
- The following deviation from the Guideline was ascertained:
The Zündwertprüfer 10-212-000 instrument works with a program according to DIN EN14522. This is a deviation from the EU-Method A.15 “Auto Ignition Temperature (liquids and gases)” as this norm is not mentioned there. An additional deviation occurs, as the method de- scribes, that after one variation of drops the 2°C test modus will start, even when an ignition has occurred (cf. the orange mark in the schema). In the DIN method 51794 steps of 5°C are proposed in this case. As shown in the schema above the endpoint of the different guidelines is the same. It is possible that more ignition trials will be conducted using the EN 14522. Therefore, this can be considered as uncritical. - GLP compliance:
- yes (incl. QA statement)

Applicant's summary and conclusion
- Conclusions:
- The value of the auto ignition temperature is 281 °C, determined using 13 drops test item. The test item showed auto ignition after 178 seconds.
- Executive summary:
In a study following EU method A.15, the value of the auto-ignition temperature is 281°C. This value was determine dusing 13 drops test item. The test item showed auto ignition after 178 seconds.
