Applicant's summary and conclusion

Conclusions:
Please see the Executive Summary for the Conclusion.
Executive summary:

The determination was carried out using a procedure designed to be compatible with Method A4 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.

 

Instrument:                                               Vapor pressure balance.

Conclusion

The vapor pressure of the test item has been determined to be less than 1.4 x 10-3Pa at 25 ºC.
