Pigments and extenders — Methods of dispersion for assessment of dispersion characteristics — Part 3: Dispersion using a high-speed impeller mill

This method is restricted to mill bases of moderately high viscosity due to either high binder concentration and/or high pigment concentration which produces high shear forces. This part is for use in conjunction with the methods of assessment described in ISO 8781, using an agreed binder system. For any particular application, the test methods specified need to be completed by supplementary information. The items are given in the annex.
