In the main test the lowest temperature where an ignition was observed was 122.0 °C.


The average measured flash point is corrected to the ambient pressure to be 123.1 °C


The resulting average corrected flash point rounded down to the nearest multiple of 0.5 °C is 123.0 °C.


 


Final results


The test item has a flash point of 123.0 °C (average corrected and rounded down to the nearest multiple of 0.5 °C) according to Regulation EC No. 440/2008 Method A.9. Flash Point and DIN EN ISO 2719 (2003).

Interpretation of results:
GHS criteria not met
Conclusions:
The flash point of the test item was determined to be 123 °C at 1013 hPa.
Executive summary:

An experimental study was conducted to determine the flash point of the test item according to Regulation EC No. 440/2008 Method A.9. and ISO 2719 using the Pensky-Martens closed cup method. In the preliminary test the lowest temperature where an ignition was observed was 124.0 °C. In the main test. the average measured flash point corrected to ambient pressure was determined to be 123.1 °C. The flash point was rounded down to the nearest multiple of 0.5 °C to be 123 °C. Therefore the test item has not to be classified as flammable liquid.

Description of key information

The flash point of the test item was determined to be 123 °C at 1013 hPa.

Key value for chemical safety assessment

Flash point at 101 325 Pa:
123 °C
