Calculated pressure: < 0.1 at 20°C and 3.411 K-1

Conclusions:
The vapour pressure of the test item at 20 °C was calculated by mathematical extrapolation using the Antoine equation. It was calculated to < 0.1 hPa (at 20 °C).
Executive summary:

The vapour pressure of the test item was determined according to OECD Guideline 104 [adopted on 23 March 2006] and EU test method A.4 [Council Regulation (EC) No 440/2008] with the dynamic method.

Description of key information
