Applicant's summary and conclusion

Conclusions:
MTDID 49220 has an extrapolated vapor pressure of 25.6 hPa (19.2 mm Hg) at 20°C, determined using the dynamic method according to ASTM E 1719-7.
Executive summary:

The vapor pressure of MTDID 49220 was determined by the dynamic method. The vapor pressure of MTDID 49220 was determined at five intervals from 38.1 °C to 111.5 °C. This data was extrapolated to determine the vapor pressure of 25.6 hPa (19.2 mm Hg) at 20°C for MTDID 49220. The test was done according to ASTM E 1719-7. Because the result was extrapolated from the measured values, the result is considered reliable with restrictions.
