Pigments and extenders - Methods of dispersion and assessment of dispersibility in plastics - Part 2: Determination of colouristic properties and ease of dispersion in plasticized polyvinylchloride by two-roll milling; German version EN 13900-2:2003
This part of EN 13900 specifies a method of determining the ease of dispersion DH/PVC-P of pigments from the differences in colour strength on dispersing colouring materials under various conditions in plasticized polyvinyl chloride (PVC-P) compounds. The method is appropriate for use with organic and inorganic colour pigments and for pigment preparations.
