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.

Results and discussion

Flash point
Key result
Flash point:
122 °C
Atm. press.:
1 013 hPa

Any other information on results incl. tables

Test 1: 122°C

Test 2: 124°C

As the difference between the results is ≤ 6°C, the lowest flash point value obtained was reported as the flash point of the substance.

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 122°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).

The flash point was determined in duplicate obtaining a lowest value of 122°C (at 1013 hPa).

ASTM D7094 is not mentioned in the EC A.9 flash point guideline but is a commonly used and safer (low sample volume) alternative for the ISO 2719 Pensky Martens closed method.
