Pigments and extenders - Methods of dispersion for assessment of dispersion characteristics - Part 4: Dispersion using a bead mill (ISO 8780-4:1990)

This method is restricted to low- and medium-viscosity mill bases allowing free movement of the grinding spheres. Therefore, it is suitable for mill bases having a viscosity higher than those for which the dispersion method is appropriate. For any particular application, the test method specified needs to be completed by supplementary information. The items are given in the annex.
