Applicant's summary and conclusion
- Conclusions:
- The vapor pressure of the test item has been determined to be 7.7 x 10-7 Pa at 25ºC.
- Executive summary:
Method
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. The vapor pressure was determined using a vapor pressure balance with measurements being made at several temperatures and linear regression analysis used to calculate the vapor pressure at 25°C.
Result
The vapor pressure of the test item has been determined to be 7.7 x 10-7 Pa at 25ºC.
