Key result

Flash point:

39 °C

Atm. press.:

1 013 hPa

Preliminary test:

The test result of the preliminary test with the search program is presented in the following table. An ignition is indicated by “+” and no ignition by “-”. In the preliminary test the lowest temperature where an ignition was observed was 40.2 °C.

Amount of test item / g	Temperature / °C	Ignition / (+/-)	Air pressure / hPa
89.26	40.2	+	1007.8

Main test:

The test results of the main test are presented in the following table. An ignition is indicated by “+” and no ignition by “-”.The average of two main tests (corrected to standard pressure of 1013 hPa) is 39.5 °C. The resulting flash point, rounded down to the next multiple of 0.5 °C, is 39.0 °C.

Amount of test item / g	Temperature / °C	Ignition / (+/-)	Air pressure / hPa	Corrected flash point / °C
89.98	39.2	+	1007.8	39.3
88.81	39.6	+	1007.8	39.7

Interpretation of results:

Category 3 (flammable liquids) based on GHS criteria

Conclusions:

The flash-point of the test item was determined to be 39.0 °C (average corrected and rounded down to the nearest multiple of 0.5 °C).

Executive summary:

A study was conducted according to Regulation EC No. 440/2008 Method A.9. Flash Point and DIN EN ISO 2719 (2016) to determine the flash point of the test item using non-equilibrium closed cup method. An Abel apparatus was used for this purpose. For the main test about 89 – 90 g of test item were added to the test vessel, which is then closed and fitted to the hot air bath. In specific temperature intervals it is tested whether the vapour phase can be ignited using a gas flame as ignition source. The flash-point of the test item was determined to be 39.0 °C (average corrected and rounded down to the nearest multiple of 0.5 °C). As the test item has a measured flash point between ≥ 23 and ≤ 60 °C, it has to be classified as flammable liquid.

Description of key information

The flash-point of the test item was determined to be 39.0 °C (average corrected and rounded down to the nearest multiple of 0.5 °C) (reference 4.11-1).

Key value for chemical safety assessment

Flash point at 101 325 Pa:

39 °C
