Conclusions:
The following surface tension result was obtained: 78.0 mN.m-1 (mean of 2 runs)
Executive summary:

Surface tension for Hydrogenated Rosin was measured by ring method according to the protocol in EU Regulation (EC) 440/2008 (test A5) and in compliance with GLP. A surface tension of 78 nN/m at 20°C was determined (mean of 2 runs).
