Materials and methods

Test guideline

Test guideline 1

Qualifier:

equivalent or similar to guideline

Guideline:

EU Method A.9 (Flash-Point)

Version / remarks:

2008

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)

Dynamic viscosity of test material:

no data

Results and discussion

Flash point

Key result

Remarks on result:

no flash point up to 100°C

Any other information on results incl. tables

It was visually observed that the test item reacted and/or degraded at approximately 139°C (second preliminary test) or 147°C (first preliminary test).

No flammable vapour/air mixture was produced at temperatures below the temperature at which reaction and/or degradation of the test item occurred. 

Applicant's summary and conclusion

Interpretation of results:

other: not classified under CLP or GHS

Conclusions:

No flash-point was observed below the temperature at which reaction and/or decomposition of the test item occurred (i.e. at approx. 139°C - 147°C).

Executive summary:

The modified continuously closed cup ASTM D7094 method (GLP study) was performed with the substance. Two experiments were performed. No flash-point was observed below the temperature at which reaction and/or decomposition of the test item occurred (i.e. at approx. 139°C - 147°C).
