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.

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.

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.

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out
through ISO technical committees. Each member body interested in a subject for which a technical
committee has been established has the right to be represented on that committee. International
organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.
ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of
electrotechnical standardization.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of any
patent rights identified during the development of the document will be in the Introduction and/or on
the ISO list of patent declarations received (see www.iso.org/patents).
