DIN EN 13900-3-2003 颜料和填充剂.扩散方法和在塑料中可扩散性的评估.第3部分:用两辊研磨测定色彩特点和黑色及彩色颜料在聚乙烯中的易扩散性
Pigments and extenders - Methods of dispersion and assessment of dispersibility in plastics - Part 3: Determination of colouristic properties and ease of dispersion of black and colour pigments in polyethylene by two-roll milling; German version EN 13900-
This part of EN 13900 specifies a method of determining in polyethylene (PE) the colouristic properties of a test pigment relative to a standard, and the ease of dispersion DH/PE of pigments from the differences in colour strength on dispersing colouring materials under various conditions. The method is appropriate for use with organic and inorganic black and colour pigments.#,,#
