Key result

Flash point:

150 °C

Atm. press.:

1 030 mBar

Interpretation of results:

GHS criteria not met

Conclusions:

From the experimental data obtained, it can be concluded that the sample of d-phenothrin technical grade produces flammable vapours which can be ignited, according to the guideline in Official Journal L 383 A.9, and the flash point of the test article, is 150 °C as the mean of the four determinations.

Executive summary:

The test article was placed into the closed apparatus, and then heated at a slow constant rate with continual stirring. A small flame was directed into the cup at regular intervals with simultaneous interruption of the stirring. The clean cup was filled to the mark point with the substance. The beginning temperature was about 25 °C, then the system was closed and the liquid stirred. The test substance was heated with a temperature increase of approximately 5 °C/min. From 25 °C the test flame was applied every 30 seconds, so that the flame was quickly lowered into the vapour space of the cup, left in this position for 2 seconds and quickly raised to its high position.

At room temperature the test article was not flammable; therefore, it was heated with a rate of 5 °C/min until 180 °C.The test was performed at an atmospheric pressure of 1030 mbar. After that, four determinations were performed on the test article with the Pensky-Martens closer tester and they showed the following result: The flash point of the test article is 150 °C, as the mean of the three tests performed.

Description of key information

A flash point test according to CIPAC MT 12.3 and OJEC A.9 methods has been performed at an atmospheric pressure of 1030 mbar.

From the experimental data obtained, it can be concluded that the sample of d-phenothrin technical grade produces flammable vapours which can be ignited, and the flash point of the test article is 150 °C as the mean of the four determinations. However, the test article does not meet the criteria to be classified under GHS as a flammable liquid.
