Conclusions:

The vapour pressure of the test item has been determined to be less than 5.1 x 10E-3 Pa at 25 °C.

Executive summary:

Test System

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.

Principle of the Test

The vapour pressure was determined using a vapour pressure balance with measurements being made at several temperatures and linear regression analysis used to calculate the vapor pressure at 25 °C.

Conclusion

The vapour pressure of the test item has been determined to be less than 5.1 x 10^-3 Pa at 25 °C.

Description of key information
