Additional information
Surface Tension:
The surface tension of the test item at two different loading rates was determined using Method A5 of Commission Directive 92/69/EEC (which constitutes Annex V of Council Directive 67/548/EEC). The results are shown in the following table:
Loading Level (g/l) (As Test Item) |
Surface Tension Result (mN/m) |
Temperature (°C) |
