- In this test, the flash point of the test item was investigated with the Flash Point Tester NPM 440 (Pensky Martens) of the company Normalab. This test equipment uses a closed cup method, corresponding to 1.6.3.2 in the Regulation EC No. 440/2008 Method A.9. Flash point. As ignition source a flame was used. The method is valid for the determination of flash points between 0°C and 410°C.
The test item was placed in a test vessel and heated to the test temperature according to the procedure described in the German standard DIN EN ISO 2719. Ignition trials were carried out in order to ascertain whether or not the sample flashed at the test temperature.
PRELIMINARY TEST
The measurement was started by a search program to determine the rough temperature range of the flash point. About 78 g of the test item were filled in the test cup and heated with a heating rate of 5 - 6 K/min. The flame was dipped in the cup for every 1 K change of temperature.
MAIN TEST
For the main test, the test item is to be filled in the cup. The estimated flash point from the preliminary test is used as target temperature for the main test. The procedure of the main test is as follows:
The first ignition trial of the main test is performed at a test item temperature 23±5 °C below the approximate flash point determined in the preliminary test, with a stirrer speed of 90 - 120 rpm and a heating rate of 5 - 6 K/min.
If the flash point is expected to be below 110 °C, then the flame is dipped in the cup at 1 K intervals.
If the flash point is expected to be above 110°C, then the flame is dipped in the cup at 2 K intervals.
In case the test item is highly viscous, a lower heating rate of 1.0 - 1.5 K/min and a higher stirrer speed of 250 ± 1 0 rpm is used, the rest of the procedure is the same as above.
The atmospheric pressure has to be documented. The main test has to be performed at least twice. If the two results differ by more than 2 K, further tests have to be performed. - GLP compliance:

- Executive summary:
In this test, the flash point of the test item was investigated, under GLP, according to Regulation EC No. 440/2008 Method A.9. and DIN EN ISO 2719 (2003), with the Flash Point Tester NPM 440 (Pensky Martens, closed cup).
The average of duplicate determinations was corrected for standard atmospheric pressure and rounded.
The test item has a flash point of 75°C.
Reference
Preliminary test
| Amount of test item/g | Temperature °C | Ignition (+/-) | Air pressure/hPa |
| 78.13 | 78.0 | + | 1004.7 |
The result "ignition" is indicated by + and "no ignition" by -.
In the preliminary test the lowest temperature where an ignition was observed was 78°C.
Main test
In the main test the lowest temperature where an ignition was observed was 75.0 °C.
Description of key information
The test item has a flash point of 75°C, corrected to standard atmospheric presssure (EU A.9/ISO 2719, PMcc method; Kremer 2018; GLP).
Key value for chemical safety assessment
- Flash point at 101 325 Pa:
- 75 °C
Additional information
A fully reliable, guideline, GLP study is available, and therefore considered as key.
