Table 2: Calibration Factor
Literature Value (mN/m)
Mean Calibration Factor = 0.998
Table 3: Sample Solution Readings
- Mean reading: 72.3 mN/m
- Surface tension:
= reading x calibration factor
= 72.3 mN/m x 0.998
= 72.2 mN/m
- Temperature: 21.8 ± 0.5
- pH of sample solution: 2.8
The surface tension of the test material was determined under GLP conditions and in accordance with the standardised guideline EU Method A.5., following the ring method.
The surface tension of the test material was determined to be 72.2 mN/m, at 21.8 ± 0.5 °C as 1.03 g/L solution of test material. As the result is greater than 60 mN/m, the test material is not considered to be surface active.
Surface tension = 72.2 mN/m at 21.8 ± 0.5 °C, 1.03 g/L solution of test material, EU Method A.5., Butler & O'Connor (2008)
The surface tension of the test material was determined under GLP conditions and in accordance with the standardised guideline EU Method A.5., following the ring method. The study was assigned a reliability score of 1 in line with the principles for assessing data quality as defined by Klimisch (1997).
