Pigments and extenders - Testing of colouring materials in plasticized polyvinyl chloride (PVC-P) - Part 3: Determination of the relative tinting strength of white pigments

This Part of EN 14469  specifies a procedure for determining the relative tinting strength of white pigments in plasticized polyvinyl chloride (PVC-P) at identical concentration of the white pigments by weight. To this end, the white pigments are incorporated into the basic mixture A (see EN 14469 -1) together with a carbon black pigment preparation.

Pigmente und Füllstoffe - Prüfung von Farbmitteln in weichmacherhaltigem Polyvinylchlorid (PVC-P) - Teil 3: Bestimmung des relativen Aufhellvermögens von Weißpigmenten

Dieser Teil von EN 14469 legt ein Verfahren zum Bestimmen des relativen Aufhellvermögens von Weißpigmenten in weichmacherhaltigem Polyvinylchlorid (PVC-P) bei gleicher Massenkonzentration der Weißpigmente fest. Dabei werden die Weißpigmente zusammen mit einer Rußpaste in Grundmischung A (siehe prEN 14469-1) eingearbeitet.

Pigments et matières de charge - Essai des matières colorantes dans le chlorure de polyvinyle plastifié (PVC-P) - Partie 3: Détermination du pouvoir colorant relatif des pigments blancs

La présente Partie de l'EN 14469 spécifie une méthode permettant de déterminer le pouvoir colorant relatif des pigments blancs dans le chlorure de polyvinyle plastifié (PVC-P), en utilisant une concentration en masse de pigments blancs identique. A cette fin, les pigments blancs sont incorporés dans le mélange de base A (voir prEN 14469-1) conjointement avec une préparation de pigment au noir de carbone.

Overview

EN 14469-3:2004 is a European standard developed by CEN that specifies a standardized procedure for determining the relative tinting strength of white pigments in plasticized polyvinyl chloride (PVC-P). This method ensures consistent evaluation of white pigments when incorporated into PVC-P materials at identical concentrations by weight. The standard supports pigment manufacturers, quality control laboratories, and plastics processors by providing a reliable testing approach aligned with regulatory expectations.

The procedure involves dispersing the white pigment in a controlled basic mixture alongside a carbon black pigment preparation, followed by milling, forming test sheets, and performing photometric measurements to calculate relative tinting power.

Key Topics

• Scope and Purpose:
  Defines how to assess the relative tinting strength of white pigments in plasticized PVC formulations to support product consistency and quality comparison.

• Preparation of Test Specimens:

  • Premixing of white pigment, basic mixture A, and carbon black pigment preparation.
  • Two-roll milling process carried out at 160 °C followed by milling at 130 °C for optimum dispersion and sheet uniformity.
  • Optional pressing of the milled sheet to improve surface finish or sample thickness for accurate photometric evaluation.

• Measurement and Evaluation:

  • Use of a photometer according to colorimetry standards (ISO 7724-2) for precise colorimetric data measurement.
  • Calculation of relative tinting strength as the ratio of the test pigment's tinting strength to that of a reference pigment, expressed as a percentage.

• Testing Materials and Equipment:

  • Basic mixture A as specified in EN 14469-1.
  • Carbon black pigment preparation based on highly dispersible grades.
  • Two-roll heated mill, heated plate press (optional), and photometric measuring devices.

• Documentation and Reporting:
  The test report must include identification of pigments, reference to EN 14469-3, photometric data, relative tinting strength results, description of materials used, deviations from the method if any, and date of testing.

Applications

• Quality Control in Pigment Manufacturing:
  Enables pigment producers to benchmark the tinting strength of white pigment batches ensuring consistent performance.

• Plastics Industry – PVC Production:
  Assists compounders and manufacturers of plasticized PVC products in selecting white pigments with optimal brightness and tinting properties, impacting final product aesthetics and quality.

• Regulatory Compliance and Standardization:
  Supports compliance with European and international norms for pigment testing, facilitating cross-border acceptance and product certification.

• Research and Development:
  Provides a scientific method for evaluating new pigment formulations or additives designed to enhance whiteness and opacity in PVC materials.
