Plastics/rubber -- Polymer dispersions and rubber latices (natural and synthetic) -- Determination of surface tension by the ring method
This standard has been revised by ISO 1409:2006
Describes the determination of the surface tension of polymer dispersions, prevulcanized latices and natural as well as synthetic rubber latices by the ring method (du Nouy-type tensiometer). Applicable for polymer dispersions with a viscosity less than 200 mPa·s. Replaces the third edition.
