Endpoint:
acute toxicity: inhalation
Data waiving:
other justification
Justification for data waiving:
the study does not need to be conducted because exposure of humans via inhalation is not likely taking into account the vapour pressure of the substance and/or the possibility of exposure to aerosols, particles or droplets of an inhalable size
Cross-reference
Reason / purpose for cross-reference:
data waiving: supporting information

Conclusions:
Calculated vapour pressure at 20 °C 1.57 E-16 kPa and at 50 °C 1.64 E-13 kPa.
Values are afflicted with high relative uncertainties.
Executive summary:

The vapour pressure was measured with OECD 104 guideline method in a temperature range from 539.59 K to 595.19 K. To the experimental data Antoine parameters were fitted. Calculated values at 20 and 50 °C are given.
