auto-ignition temperature (liquids)
Type of information:
experimental study
Adequacy of study:
key study
Study period:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
guideline study without detailed documentation
according to guideline
EU Method A.15 (Auto-Ignition Temperature (Liquids and Gases))
equivalent or similar to guideline
other: German standard method "DIN 51794"
GLP compliance:
Other quality assurance:
ISO/IEC 17025 (General requirements for the competence of testing and calibration laboratories)
Specific details on test material used for the study:
BTS sample number: 120027
Key result
Auto-ignition temperature:
415 °C
Atm. press.:
1 002 hPa
Remarks on result:
other: The result is not reported as the mean, but as the lowest value, where no ignition occurs.

The lowest result of an ignition was found in the main tests at 420 °C. The barometric pressure was 1002 hPa at the time of the test runs.

An auto-ignition temperature of 415 °C was measured at 1002 hPa.
Executive summary:

According to EC Test Procedure A.15 'Auto-ignition temperature (liquids and gases)' an auto-ignition temperature of 415 °C was determined (1002 hPa).

Bearing in mind the significance of the ignition temperature for risk assessment, the result is not reported as the mean, but as the lowest value, where no ignition occurs.

Description of key information

For methyl valerate an autoignition temperature of 415 °C was obtained at 1002 hPa.

Key value for chemical safety assessment

Autoflammability / Self-ignition temperature at 101 325 Pa:
