The highest values were discarded (values in grey italics, first and second main study). For the final evaluation, the values from the third, the fourth and the fifth main study were used.

The lowest value of the auto ignition temperature is 247 °C.

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.

Conclusions:
In this study, three independent determinations allowed to determine an auto ignition temperature of 245°C for D-LIMONENE (5989-27-5).
Executive summary:

A study was performed according to EU A.15 guideline to determine the auto-ignition temperature of d-limonene.

The lowest measured value of five experiments was 247°C. According to the followed guideline, the auto-ignition temperature should be the lowest value from the lowest values of three experiments rounded down to a whole multiple of 5°C. The final auto-ignition temperature of d-limonene was stated as 245°C.

The study having been conducted under GLP and without deviation, this result is considered as reliable without restriction.

Conclusions:
The reported auto ignition temperature of d-limonene was 237 °C.
Executive summary:

The auto ignition temperature of d-limonene was reported in the Priority Existing Chemical Assessment Report No. 22 of the National Industrial Chemicals Notification and Assessment Scheme (NICNAS) as 237°C.

Description of key information

The Self-ignition temperature of d-limonene at atmospheric pressure is 245 °C.

Key value for chemical safety assessment

Autoflammability / Self-ignition temperature at 101 325 Pa:
245 °C

Additional information

Well described key study conducted according to Guideline and under GLP to determine the self-ignition temperature. The result was considered as reliable without restriction and is supported by another data from secondary literature which is in agreement with the key value.
