Publication date:   Jan 30, 2004

Scope

This part of EN ..... 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.
