Gives a method for the dispersion of pigments and extenders using a bead mill. It is for use in conjunction with the methods of assessment described in ISO 8781, using an agreed binder system of low viscosity. Restricted to low- and medium-viscosity mill bases allowing free movement of the grinding spheres. Suitable for mill bases having a viscosity higher than those for which the dispersion method described in ISO 8780-2 is appropriate. BS AMD 8527 RENUMBERS THIS STANDARD TO BS EN ISO 8780/4
