適用范圍：This European Standard specifies a method for the determination of the solubility of ionic surface active agents inwater as a function of concentration and temperature and for the determination of the Krafft point by graphicalevaluation of the measurement results.In the temperature range from 0 °C to 90 °C, the solubility is determined without any limitations if the viscosity ofthe solution does not exceed about 700 mPas.At temperatures below 0 °C, determination is only possible if the solvent does not freeze.The method is applicable both to pure surface active agents and to technical products optically clear and notunduly coloured solutions.The solubility both of solid and liquid surface active agents and of aqueous solutions of surface active agents isdetermined by the method specified.
