- Endpoint:
- auto-flammability
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 2013
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- other: The study has been conducted according to internationally recognised guideline. No deviation is reported. The substance is adequately characterised. Therefore full validation applies.
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.15 (Auto-Ignition Temperature (Liquids and Gases))
- Deviations:
- no
- Qualifier:
- according to guideline
- Guideline:
- other: DIN 51794:2003-05
- Deviations:
- no
- Principles of method if other than guideline:
- Not applicable
- GLP compliance:
- no
- Auto-ignition temperature:
- 265 °C
- Atm. press.:
- 98 925 - 100 666 Pa
- Remarks on result:

- Conclusions:
- The auto ignition temperature of Rosemary oil was determined to be 265 °C at 98925-100666 Pa.
- Executive summary:
The auto-ignition temperature of Rosemary oil was measured according to EU A.15/DIN 51794 guideline. Three main tests were performed, the relevant parameters were recorded, and results ranged between 265 and 275 °C. The lowest result, rounded down to 5 °C, i.e. 265 °C, is retained.

- Detailed findings for each step are provided in the experimental report.
- Atmospheric pressure ranged between 98925 and 100666 Pa during the study.
- The lowest measured value of the auto ignition temperature is 265 °C.
- The auto ignition temperature (result of determination) is the lowest value from the three experiments, rounded down to a whole multiple of 5°C. Therefore, the auto ignition temperature is stated as 265 °C.
