experimental study
Adequacy of study:
key study
Study period:
08-05-2012 - 10-05-2012
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:
yes (incl. QA statement)
Specific details on test material used for the study:
- Name of test material (as cited in study report): Jeffcat ZR50
- Physical state: Liquid
- Batch: PFW100207
- Composition of test material, percentage of components: contains 0.03% water
- Storage conditions: in cool, well-ventilated area
Auto-ignition temperature:
227 °C
Atm. press.:
100.9 kPa
Remarks on result:
other: The auto-ignition temperature measured (227°C) was corrected for barometric pressure to 227.1°C.

No cool flames were observed. Ignition produced an orange flame.

Time lag at the auto-ignition temperature was 6 seconds.

Sample quantity at lowest auto-ignition temperature: 150 µL

The auto-ignition temperature of the substance was determined to be 227°C at atmospheric pressure.

Description of key information

The auto-ignition temperature of the test substance was determined in a GLP-compliant study according to the test method EC A.15 to be 227°C at 100.9 kPa (Younis S, 2012).

Key value for chemical safety assessment

Autoflammability / Self-ignition temperature at 101 325 Pa:
227 °C

Additional information

When correcting to standard atmospheric pressure, the rounded value of the test result remains identical (227°C).
