- Conclusions:
- The surface tension of a 8.28e-5 g/l solution of test material has been determined to be 72.6 mN/m at 21.0 ± 0.5 °C. The surface tension of a 7.93e-3 g/l solution of test material has been determined to be 65.6 mN/m at 21.0 ± 0.5 °C. The test material is considered not to be a surface active material.
- Executive summary:
Surface Tension. 72.6 mN/m (8.28 x 10-5 g/l solution), 65.6 mN/m (7.93 x 10-3 g/l solution) at 21.0 ± 0.5 °C, using a ring method based on ISO 304 and Method A5 of Commission Directive 92/69/EEC. The test material is considered not to be a surface-active material.
