Test results:

Results of preliminary test, Pensky-Martens:

The result of the preliminary test with the search program is summarized in the following table. An ignition is indicated by + and no ignition by -.

Preliminary test

Amount of test item / g	Temperature / °C	Ignition (+/-)	Air pressure / hPa
76.58	-	-	1008.2

 

Prior to the measurement a sample of the test item was heated up to 55 °C due to the high viscosity of the test item. The test was terminated at 255.8 °C, due to the fact that the test item clumped together and was jellylike. Up to 255.8 °C no flash point could be observed. Further tests were performed with the Rapid-Tester.

The test results of the pre-test with the search program are presented in the following table. An ignition is indicated by + and no ignition by -.

Preliminary test

Amount of test item / g	Temperature / °C	Ignition (+/-)	Air pressure / hPa	Remark
2	100.5	-	988.4	No ignition up to 100 °C
4	212.2	-		Flame extinguished, no visual ignition

 

In the preliminary test no ignition was observed up to a temperature of 212.2 °C. The flame extinguished at this temperature.

Main test

The test results of the main test are presented in the following table. An ignition is indicated by + and no ignition by -.

In the main test the lowest temperature where an ignition was observed was 210.5 °C.

The measured flash point is corrected to the ambient pressure to be 211.1 °C.

The resulting average corrected flash point rounded down to the nearest multiple of 0.5 °C is 211.0 °C.

Description of key information

Flash point = 211 °C at 987.7 hPa (A.9., ISO 3069)

Additional information

The flash point of the test item was determined using the rapid equilibrium closed cup method according to EU Method A.9., ISO 3069.
