Executive summary:

In the Klimisch 1 GLP-study Smekay (2017) determined the vapour pressure of the registered substance according to OECD 104 and EU A.4. using the effusion method (Knudsen cell) At 20"C the vapour pressure was determined to be 0.008 Pa.

The information is considered relevant and reliable for the risk assessment.
