- Version / remarks:
- 2002. Remark: DIN EN ISO 2719
- Type of method:
- non-equilibrium method closed cup
- Flash point:
- 129 °C
- Atm. press.:
- 101.3 kPa
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- The flash point of the test item is 129 ± 2 °C at 101.3 kPa.
- Executive summary:
The flash point of the test substance was determined according to EU method A.9 and DIN EN ISO 2719 using a Pensky-Martens apparatus. At 101.3 kPa, the flash point is 129 +/- 2 °C.
Reference
The measurement gave the following results:

Status |
#1 Sel |

#2 Enl |
123.2 |
Yes |
Rejected |
| #3 Enl | 129.3 | Yes | OK |
| #4 Enl | 129.3 | Yes | OK |
Measurement #4 was performed because of the discrepancy between measurements #2 and #3. In view of the result, measurement #2 was rejected as too low. The flash point is taken as the rounded mean value of the two measurements that are in satisfactory agreement (#3 and #4), giving a value of 129 °C. The mean atmospheric pressure was 100.3 kPa for the two selected values; the result quoted is corrected to standard atmospheric pressure, 101.3 kPa. Based on the general experience with the method, the error is quoted as ± 2°C.
Description of key information
The flash point of the test item is 129 ± 2 °C at 101.3 kPa.
Key value for chemical safety assessment
- Flash point at 101 325 Pa:
- 129 °C
