Full test results:

 Test N° Test temperature (°C)  Solution age (minutes)  Surface tension reading (mN/m)  Corrected value using calibration factor* (mN/m)  Corrected value for Harkins-Jordan Correction** (mN/m) 
 1  20  5  68.5  74.9  74.9
 2  20  10  69.0  75.5  75.5

Result : 75.2 mN.m-1 (mean value)

Note:

Measured value of the surface tension of water : 66.5 mN.m-1

EC standard reading for surface tension of water : 72.75 mN.m-1

Calibration factor is: (72.75 / 66.5) = 1.094

* The calibration factor is determined by measuring the Surface Tension of water and comparing the value obtained in literature.

** The corrected value is taken from a table compiled on the basis of the Harkins-Jordan correction. This correction factor is dependent on the dimensions of the measurement ring.

Conclusions:
The surface tension was determined to be 75.2 mN.m-1 (mean value) at 20°C.
Executive summary:

The surface tension test, (RING method), is conducted in accordance with the procedure described in EU Regulation (EC) 440/2008, Annex Part A test A5.

The surface tension was determined to be 75.2 mN.m-1 (mean value) at 20°C.
