The calculated vapour pressure of the substance (Table 4) was outside of the validated range of the method. Therefore vapour pressure of the substance is reported as less than the vapour pressure of bezo(ghi)perylene i.e. the reference substance with the lowest vapour pressure used during validation of the method.

Conclusions:
The vapour pressure of the substance at 20°C (293K) is < 1.3E-8 Pa and at 25°C (298K) is < 1.9E-8 Pa.
Executive summary:

The calculated vapour pressure of the substance was outside of the validated range of the method. Therefore vapour pressure of the substance is reported as less than the vapour pressure of bezo(ghi)perylene i.e. the reference substance with the lowest vapour pressure used during validation of the method.
