Flash point
Administrative data
Link to relevant study record(s)
- Endpoint:
- flash point of flammable liquids
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 20.10.05 - 20.03.06
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.9 (Flash-Point)
- Version / remarks:
- 67/548/EEC
- Deviations:
- no
- GLP compliance:
- yes
- Type of method:
- closed cup
- Flash point apparatus:
- Pensky-Martens apparatus
- Key result
- Flash point:
- 167.5 °C
- Atm. press.:
- 1 013.3 hPa
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- The flash point of the test item is 167.5 °C under atmospheric conditions (1013.3 hPa).
- Executive summary:
The flash point was determined according to EU method A.9 in a closed cup experinment according to Pensky-Martens. The test item was liquefied at 40 °C for two hours and filled into the test vessel, which was progressively heated (8.5 K/min for the preliminary test and 5.5 K/min for the main test) until the vapour reached a sufficiently high concentration in air to produce a flammable mixture which could be ignited. The final flash point rounded down with an accuracy of 0.5 K was determined to be 167.5 °C.
Reference
Before measurement the test item was liquefied at 40 °C for two hours and filled into the test vessel.

* This data point was determined by the preliminary test (heating rate 8.5 K/min) and was not used for
the determination of the final flash point.
** This data point was determined by heating rate 5.5 K/min, as proposed in DIN EN ISO 2719.
The mean flash point corrected to 1013 hPa is 167.69 °C. The final flash point rounded down with an accuracy of 0.5 K is 167.5 °C.
Description of key information

Key value for chemical safety assessment
- Flash point at 101 325 Pa:
- 167.5 K
