* The aperture measured until 136 °C and found no flash point. Therefore the program was changed to EN ISO 2719-A.

The flash point is given as the mean value of the duplicate determination. The measured flash point is therefore 114.5°C (corresponding to 387.7 K).

Interpretation of results:
GHS criteria not met
Conclusions:
The flash point is given as the mean value of the duplicate determination. The measured flash point is therefore 114.5 °C (corresponding to 387.7 K).
Executive summary:

This study was performed in order to determine the flash point of test item according to EU Method A.9, using a Pensky-Martens apparatus.

The flash point is given as the mean value of the duplicate determination. The measured flash point is therefore 114.5 °C (corresponding to 387.7 K).

The test item should NOT be classified according to Regulation (EC) 1272/2008 (CLP regulation) and UN Globally Harmonised System (GHS).

Description of key information

The flash point of test item was determined to be 114.5°C. This value is the mean value of two independant determinations.

Test item is not classified as flammable liquid according to Regulation (EC) 1272/2008 (CLP regulation) and UN Globally Harmonised System (GHS)

Key value for chemical safety assessment

Flash point at 101 325 Pa:
114.5 °C

Additional information

A fully reliable experimental study, conducted according to EU A9 guideline is available.

It is considered as a key study, and the result is retained as key data.
