Materials and methods

Test guideline

Test guideline 1

Qualifier:

equivalent or similar to guideline

Guideline:

EU Method A.9 (Flash-Point)

Version / remarks:

2016

Test guideline 2

Qualifier:

according to guideline

Guideline:

other: ASTM D7094: “Standard Test Method for Flash Point by Modified Continuously Closed Cup (MCCCFP) Tester”

Version / remarks:

2012

Deviations:

not specified

Principles of method if other than guideline:

According to ECA.9 the flash point can be determined by an equilibrium method or a non-equilibrium method. Several methods are mentioned in the guideline. ASTM D7094 is not one of the methods mentioned in the guideline but is a commonly used and safer (low sample volume) alternative for the non-equilibrium ISO 2719 Pensky martens closed cup method.

GLP compliance:

yes

Type of method:

other: modified continuously closed cup

Flash point apparatus:

other: Eraflash (Eralytics, Austria)

Results and discussion

Flash point

Key result

Flash point:

140 °C

Atm. press.:

1 013 hPa

Any other information on results incl. tables

Test 1: 140°C

Test 2: 149°C

Test 3: 142°C

Test 4: No flash point < 151°C

The difference between the results obtained from the four tests (test 1, 2, 3 and 4) was > 6°C. The results were outside the prescribed criteria, however since the results were consistent and the best possible to achieve no further testing was performed. For safety reasons the lowest flash-point obtained is reported.

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 140°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 to be 140°C (at 1013 hPa).
