Applicant's summary and conclusion

Conclusions:
The vapor pressure of MTIDID 28640 is 0.5 Pa (0.004 mm Hg) at 20 °C as determined by EU Method A.4.
Executive summary:

The vapor pressure of MTDID 28640 was determined by the static method. The vapor pressure of MTDID 28640 at 10 °C intervals from 30 °C to 70 °C was determined in two runs. This data was extrapolated to determine the vapor pressure of 0.5 Pa (0.004 mm Hg) at 20°C for MTDID 28640. The test was done according to EU Method A.4 and was GLP compliant. Because the result was extrapolated from the measured values, the result is considered reliable with restrictions.
