Applicant's summary and conclusion

Conclusions:
The vapor pressure was determined to be 7.36E-3 Pa at 25 °C and 0.229 Pa at 70 °C.
Executive summary:

The vapor pressure of the test material has been determined at two temperatures using the vapor pressure balance method, designed to be compatible with Method A.4 Vapour Pressure of Commission Regulation (EC) No 440/2008 of 30 May 2008 and Method 104 of the OECD Guidelines for Testing of Chemicals, 23 March 2006, resulting in a vapor pressure of 7.36E-3 Pa at 25 °C and 0.229 Pa at 70 °C.
