- Atm. press.:
- 101.3 kPa
Any other information on results incl. tables
The measurement gave the following results:

Status |
| #1 Sel | 160.1 | No | Prelim |
| #2 Enl | 151.9 | Yes | Rejected |
| #3 Enl | 166.2 | Yes | OK |
| #4 Enl | 165.2 | 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 high.
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 166 °C.
The mean atmospheric pressure was 100.5 kPa for the two selected values; the results quoted are corrected to standard atmospheric pressure, 101.3 kPa. Based on the general experience with the method, the error is quoted as ± 2°C.
Applicant's summary and conclusion
- Conclusions:
- The flash point of the test item is 166 ± 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 166 +/- 2 °C.
