Pigments and extenders - Methods of dispersion and assessment of dispersibility in plastics - Part 4: Determination of colouristic properties and ease of dispersion of white pigments in polyethylene by two-roll milling (ISO 23900-4:2015)

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.

Pigmente und Füllstoffe - Dispergierverfahren und Beurteilung der Dispergierbarkeit in Kunststoffen - Teil 4: Bestimmung der koloristischen Eigenschaften und der Dispergierhärte von Weißpigmenten in Polyethylen im Walztest (ISO 23900-4:2015)

Pigments et matières de charge - Méthodes de dispersion et évaluation de l'aptitude à la dispersion dans les plastiques - Partie 4: Détermination des propriétés colorimétriques et de la facilité de dispersion des pigments blancs dans le polyéthylène par calandrage sur bicylindre (ISO 23900-4:2015)

ISO 23900-4:2015 spécifie une méthode permettant de déterminer les propriétés colorimétriques d'un pigment d'essai dans du polyéthylène (PE) par rapport à un étalon, et la facilité de dispersion DHPE des pigments à partir des différences de pouvoir colorant lorsque des matières colorantes sont dispersées dans différentes conditions.
Cette méthode convient pour une utilisation avec des pigments blancs.
La facilité de dispersion déterminée de cette manière n'est valable que pour l'équipement, les conditions et le milieu de dispersion utilisés. La mise en ?uvre de conditions d'essai différentes de celles spécifiées peut conduire à des résultats différents; cela vaut pour la valeur absolue et pour le rapport entre les valeurs obtenues pour la facilité de dispersion des divers pigments. L'indice DHPE est donc utilisé pour désigner la valeur obtenue comme spécifié dans la présente partie de l'ISO 23900.

Pigmenti in polnila - Metode dispergiranja in ocenjevanje disperzibilnosti v polimernih materialih - 4. del: Določevanje barvnih lastnosti in dispergiranja belih pigmentov v polietilenu z valjanjem z dvema valjčkoma (ISO 23900-4:2015)

ISO 23900-4:2015 določa postopek za določanje barvnih značilnosti preskusnega pigmenta v polietilenu (PE) glede na standard in dispergiranje pigmentov DHPE na podlagi razlik v barvni jakosti pri dispergiranju barvnih materialov v različnih pogojih. Metoda je primerna za uporabo z belimi pigmenti.
