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:
- 31.08. - 12.12.2006
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Remarks:
- The study was conducted according to EU guideline.
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.9 (Flash-Point)
- Version / remarks:
- 92/69/EEC
- GLP compliance:
- yes (incl. QA statement)
- Type of method:
- closed cup
- Flash point apparatus:
- Pensky-Martens apparatus
- Key result
- Flash point:
- 49 °C
- Atm. press.:
- 1 013.3 hPa
- Conclusions:
- The flash point of the test item is 49.0 °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 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 49.0 °C.

53.5 | 50.0** | 1018.8 | 49.855 |
55.6 | 49.0** | 1018.8 | 49.855 |
* 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 49.36 °C. The final flash point rounded down with an accuracy of 0.5 K is 49.0 °C
Description of key information
The final flash point rounded down with an accuracy of 0.5 K was determined to be 49.0 °C.
Key value for chemical safety assessment
- Flash point at 101 325 Pa:
- 49 °C
