ISO 23900-5:2015 spécifie une méthode permettant d'évaluer le degré de dispersion d'un pigment dans un polymère thermoplastique. Cette méthode convient pour la mise à l'essai de pigments sous forme de concentrés colorés dans tous les polymères utilisés dans le domaine de l'extrusion et de la fabrication de fibres. La valeur de pression du filtre (VPF) déterminée conformément à…

ISO 23900-6:2015 spécifie une méthode d'évaluation du degré de dispersion des pigments[1] et/ou des matières de charge dans un polymère thermoplastique. Cette méthode convient pour la mise à l'essai de pigments et/ou de matières de charge sous forme de concentrés ou de composés dans tous les polymères utilisés pour l'extrusion. NOTE Les gels, tachetures noires, trous dans le…

ISO 23900-1:2015 provides an introduction to the various parts of ISO 23900 which describe methods for dispersing pigments and extenders in plastics materials in order to determine their dispersion characteristics and colouristic properties. Methods of assessing dispersion characteristics are described in the subsequent parts of ISO 23900. The various procedures described permit comparison to be…

ISO 23900-2:2015 specifies a method of determining the colouristic 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 (PVC-P) compounds. The method is appropriate for use with organic and inorganic black and colour…

ISO 23900-3:2015 specifies a method of determining in polyethylene (PE) the colouristic properties of a test pigment relative to a standard, and the ease of dispersion DHPE of pigments from the differences in colour strength on dispersing colouring materials under various conditions. Method A is appropriate for use with organic powder pigments and carbon black pigments in powder form, many of…

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.

ISO 23900-5:2015 specifies a method of assessing the degree of dispersion of a colorant in a thermoplastic polymer. The method is suitable for testing colorants in the form of colour concentrates in all polymers used for extrusion and melt-spinning processes.

ISO 23900-6:2015 specifies a method assessing the degree of dispersion of colorants and/or extenders in a thermoplastic polymer. The method is suitable for testing colorants and/or extenders in the form of concentrates or compounds in all polymers used for extrusion processes.
