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:

closed cup

Remarks:

Modified

Flash point apparatus:

other: Eraflash (Eralytics, Austria)

Dynamic viscosity of test material:

no data

Results and discussion

Flash point

Key result

Flash point:

151 °C

Atm. press.:

1 013 hPa

Any other information on results incl. tables

Test 1: 152°C

Test 2: 151°C

Test 3: 155°C

The result of the Test 1 was > 28°C from the starting temperature of the ignition source. The result of this test was therefore not taken into account.

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 151°C.

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 151°C.
