Additional information

The determination of the surface tension of an aqueous solution of cesium sulphate was performed according to OECD Guideline 115 and EU Method A.5. The surface tension of the test item was determined two times in ten measurements. The measurements revealed values of 69.49 to 72.70 mN/m at 20 °C. The surface tension of cesium sulphate was determined to be 71.1 mN/m at 20 °C and a concentration of 1 g/L.
