Pigments and extenders - Methods of dispersion and assessment of dispersibility characteristics in plastics - Part 2: Determination of colouristic properties and ease of dispersion in plasticized polyvinyl chloride by two-roll milling
This part of this European standard specifies a method of determining the coloristic properties of a test pigment relative to a standard, and the ease of dispersion DHpvc-p of pigments from the differences in colour strength on dispersing colouring materials under various conditions in plasticized polyvinyl chloride compounds.
