- Auto-ignition temperature:
- ca. 245 °C
- Atm. press.:
- ca. 1 016 mBar
- Remarks on result:
- other: The auto ignition temperature (result of determination) is the lowest value from the lowest values of three experiments, rounded down to a whole multiple of 5 °C.
- Conclusions:
- The test substance was determined to have an auto-ignition temperature of 245°C at ca 1016 mBar.
- Executive summary:
A GLP study was conducted to determine the auto ignition temperature of test item in compliance EU-Method A.15 (referring to DIN 51794), SOP 118 009 62, and DIN EN 14522.
The auto ignition temperature was determined in three independent determinations. A lowest value of the main test of 246 °C was found.
Therefore, the auto-ignition temperature according to EU A.15 (rounded down to a whole multiple of 5 °C) of DAVANA ESSENTIAL OIL D04035 is stated as 245 °C at 1016 mBar.
Reference
Result
The requirements for repeatability of the DIN standard are stated as follows: Three lowest values of the main test have to lie within a range of 5 °C (if auto ignition temperature is below 300 °C) respectively 10 °C (if auto ignition temperature is above 300 °C).
The following lowest values were recorded:
Experiment | Value (rounded to integer) | Ignition delay | Drops used |
First test series | 246 °C | 35 s | 9 |
Second test series | 246 °C | 30 s | 5 |
Third test series | 246 °C | 24 s | 5 |
The lowest value of the auto ignition temperature is 246 °C. This value was determined using 5 drops test item. The test item showed auto ignition after 30 seconds.
The auto ignition temperature (result of determination) is the lowest value from the lowest values of the three experiments, rounded down to a whole multiple of 5 °C.
Therefore, the auto ignition temperature is stated as 245 °C.
Validity
In the DIN, the following limits are applied to the range of lowest values which may be used
for evaluation:
Table 9.2-a Acceptable ranges
| Auto ignition temp. | Range |
| < 300 °C | difference between three values of the main test max. 5 °C |
The three lowest values of the main test lay within a range of 10 °C (as required for auto ignition temperatures above 300 °C).
The largest difference between measured ignition temperatures was 0 °C.
Description of key information
The test substance was determined to have an auto-ignition temperature of 245°C at ca 1016 mBar.
No particular hazard is anticipated in normal conditions of storage
Key value for chemical safety assessment
- Autoflammability / Self-ignition temperature at 101 325 Pa:
- 245 °C
Additional information
A fully reliable experimental study, conducted according to a recognized EC method and under GLP, is available. It is considered as a key study.
This parameter is not relevant for classification, however the information is useful regarding process safety and potential additional fire hazard.
