Language in which you want to receive the document.


ISO 23900-4:2015 specifies a method of determining the colouristic properties of a test pigment in polyethylene (PE) relative to a standard, and the ease of dispersion DHPE of pigments from the differences in tinting strength of dispersing colouring materials under various conditions. The method is appropriate for use with white pigments.
