适用范围：This International Standard specifies a ring method for the determination of the surface tension of polymerdispersions and rubber latices (natural and synthetic),The method is valid for polymer dispersions and rubber latices with a viscosity less than 200 mPa-s. Toachieve this, the dispersion or latex is diluted with water to a mass fraction of total solids of 40 %. If necessary,the solids content is further reduced to ensure that the viscosity is under the specified limit.The method is also suitable for prevulcanized latices and compounded materials.
