Applicant's summary and conclusion

Conclusions:
Following test method ASTM D2879 (isoteniscope) the vapor pressure of BT4 at 26.8°C was determined to be 1.3 mmHg.
Executive summary:

The vapor pressure at 26.8oC for BT4 was assessed in neat form and following ASTM D2879. The ASTM method requires the use of an isoteniscope and involves 3-4 measurements of vapor pressures at different temperatures. Once the 3-4 vapor pressure data points have been defined based on the Temperature vs. Pressure relationship, a mathematical extrapolation is applied to determine the vapor pressure at room temperature. Based on this approach per ASTM D2879, the vapor pressure of BT4 at 26.8°C was determined to be 1.3 mmHg.
