Type of information:
experimental study
Adequacy of study:
key study
Study period:
2013-10-21 - 2013-10-31
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
guideline study
according to guideline
EU Method A.15 (Auto-Ignition Temperature (Liquids and Gases))
GLP compliance:
Specific details on test material used for the study:
- Name of test material (as cited in study report): Dimethyl Piperazine
- Substance type: Clear liquid
- Physical state: Liquid
- Lot/batch No.: 1903-3/2012
Key result
Auto-ignition temperature:
182 °C
Atm. press.:
101.1 kPa
Remarks on result:
other: The auto-ignition temperature measured (182°C) was corrected for barometric pressure to 182°C.

No cool flames were observed. Ignition produced an orange flame and small quantities of grey smoke.

Time lag at the auto-ignition temperature was 10 seconds.

Sample quantity: 200 µL

The auto-ignition temperature of the substance was determined to be 182°C at atmospheric pressure.

Description of key information

The auto-ignition temperature of the test substance was determined in a GLP study according to test method EC A.15 to be 182 °C at atmospheric pressure (Younis, 2013).

Key value for chemical safety assessment

Autoflammability / Self-ignition temperature at 101 325 Pa:
182 °C

Additional information

The test result (182 °C) was obtained at 101.1 kPa and corrected to standard atmospheric pressure.
