- remark of reviewer:
Several non-equilibrium methods are mentioned in the EC A.9 guideline. According to the study report the study was performed according to ISO Guide 2719 (Pensky-Martens closed cup). However, from the description of the test performance and the flash-point tester it was concluded that ASTM D7094 (modified continuously closed cup) is more applicable. ASTM D7094 is not mentioned in the EC A.9 guideline but is a commonly used and safer (low sample volume) alternative for the ISO 2719 method. - GLP compliance:
- yes

- non-equilibrium method closed cup
- Flash point apparatus:
- other: Eraflash (Eralytics, Austria)

Applicant's summary and conclusion
- Interpretation of results:
- other: not classified under CLP or GHS
- Conclusions:
- The flash point of the substance was determined to be 126°C (at 1013 hPa).
- Executive summary:
The flash point of the substance was determined using the modified continuously closed cup ASTM D7094 method (GLP study). Duplicate measurements resulted in a flash point of 126°C (at 1013 hPa).
