Pigments and extenders - Methods of dispersion and assessment of dispersibility in plastics - Part 3: Determination of colouristic properties and ease of dispersion of black and colour pigments in polyethylene by two-roll milling (ISO 23900-3:2015)

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 which are subject to compaction (reagglomeration under pressure), for inorganic pigments in powder form and for pigment preparations in powder or flake form.
Method B is appropriate for testing pigments and pigment preparations in granular form and for inorganic pigments in any form.

ISO 23900-3:2015 spécifie une méthode permettant de déterminer dans le polyéthylène (PE) les propriétés colorimétriques d'un pigment d'essai par rapport à un étalon, ainsi que la facilité de dispersion DHPE des pigments à partir des différences d'intensité de couleur lorsque des matières colorantes sont dispersées dans différentes conditions.
La méthode A convient pour les pigments organiques en poudre et pour les pigments au noir de carbone sous forme de poudre, qui sont, dans un grand nombre de cas, sujets au compactage (réagglomération sous pression); elle peut également être utilisée avec les pigments inorganiques en poudre et avec les préparations de pigments, en poudre ou sous forme de flocons.
La méthode B est appropriée aux essais de pigments et de préparations de pigments sous forme granulaire ainsi qu'aux essais de pigments inorganiques quelle que soit leur forme.
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 23900-3:2015 določa postopek za določanje barvnih značilnosti preskusnega pigmenta v polietilenu (PE) glede na standard in dispergiranje pigmentov DHPE na podlagi razlik v intenzivnosti barve pri dispergiranju barvnih materialov v različnih pogojih.
Metoda A je primerna za uporabo z organskim pigmentnim prahom in črnimi ogljikovimi pigmenti v obliki prahu, od tega se na mnogih opravi zgoščevanje (vnovična aglomeracija pod tlakom), za uporabo z anorganskimi pigmenti v prahu in za pripravo pigmentov v obliki prahu ali kosmičev.
Metoda B je primerna za preskušanje pigmentov in pripravo pigmentov v granularni obliki in za anorganske pigmente v kateri koli obliki.

Overview

EN ISO 23900-3:2018 (ISO 23900-3:2015) defines a standardized laboratory method for assessing the colouristic properties and ease of dispersion of black and colour pigments in polyethylene (PE) using two-roll milling. The standard quantifies dispersion performance by measuring changes in colour strength relative to a standard reference (e.g., titanium dioxide or a well-dispersed masterbatch) and reports an ease-of-dispersion value designated DH_PE. Results are specific to the dispersion medium, equipment and conditions used.

Key topics and requirements

• Scope: Applies to pigments and pigment preparations dispersed in polyethylene. Provides two alternative test routes:
  • Method A - for organic powder pigments, carbon black powders (including compactible/reagglomerating grades), inorganic powder pigments, and powder/flake pigment preparations.
  • Method B - for pigments and pigment preparations in granular form and for inorganic pigments in any form.
• Principle: Dispersion on a two-roll mill at controlled temperature and gap settings, cooling and subsequent high-shear re-milling; the increase in colour strength after re-milling is used to calculate DH_PE.
• Reference material: Uses a well-dispersed titanium dioxide pigment or an agreed masterbatch as the comparative standard.
• Measurements: Colour strength assessed by photometric/colourimetric methods (relative tinting strength), with prepared sheets pressed and measured according to referenced photometric norms.
• Apparatus note: Two-roll mill with heating and adjustable roller spacing; typical roll diameters specified in the document (e.g., between 80 mm and 200 mm).
• Limitations: DH_PE values are valid only for the specified dispersion equipment, conditions and medium. Different test parameters can change absolute values and relative rankings.

Applications and users

Who uses this standard:

• Pigment manufacturers evaluating dispersibility and colouristic performance of new pigments (organic, inorganic, carbon black).
• Compounders and masterbatch producers validating pigment behaviour in polyethylene formulations.
• Quality control and R&D laboratories comparing batches, optimizing formulations or troubleshooting dispersion issues.
• Purchase/specification teams and regulatory bodies requiring standardized dispersion data for supplier claims.

Practical benefits:

• Objective, repeatable comparison of pigment dispersibility.
• Data to guide processing choices (mill settings, polymer grade) and formulation optimization.
• Support for product specifications, supplier selection and technical communication between pigment and plastics industries.

Related standards

• Other parts of ISO 23900 series (Part 1 general introduction; Part 2 PVC two-roll milling; Part 4 white pigments in PE; Parts 5–6 alternative dispersion tests).
• Photometric reference methods (e.g., ISO 787‑24) and sampling standards (e.g., ISO 15528).
