Pigments and extenders - Methods of dispersion and assessment of dispersibility in plastics - Part 1: General introduction; German version EN 13900-1:2003
This part of EN 13900 provides an introduction to the various parts of EN 13900 which describe methods for dispersing pigments and extenders in plastics materials in order to determine their dispensibility. Methods of assessing the ease of dispersion are described in the subsequent parts of EN 13900. The various procedures described permit comparisons to be made between similar pigments (for example between a test sample and an agreed reference pigment).
