Overview

EN 14469-2:2004 is a European standard developed by CEN that specifies procedures for the preparation of test specimens used in evaluating colouring materials in plasticized polyvinyl chloride (PVC-P). As part two of the EN 14469 series, this standard focuses on the method of preparing test samples that allows accurate testing of pigment properties in PVC-P materials. It applies to a broad range of pigments including inorganic and organic types, as well as pigment preparations in powder, paste, or granular forms.

This standard plays a critical role in ensuring consistent and reproducible testing conditions, which translates to reliable results when evaluating pigment performance in plasticized PVC applications.

Key Topics

• Scope and Applicability
  EN 14469-2 applies to coloring materials tested within plasticized PVC matrices. It is designed for use with both pigments and pigment preparations as detailed in EN 14469-1, covering testing for specific pigment properties.

• Preparation Procedure
  The standard outlines step-by-step processes for:

  • Sampling colouring materials in compliance with EN ISO 15528.
  • Premixing pigments with a predefined PVC basic mixture to achieve homogeneity.
  • Milling the pigment-PVC mixture on a heated two-roll mill under controlled settings to form test sheets of uniform thickness (0.4 mm to 0.5 mm).
  • Pressing milled sheets under specific temperature and pressure conditions to improve surface quality and sample thickness for photometric analysis.

• Required Equipment
  Key apparatus includes:

  • Mixing vessels or beakers for premixing pigment and PVC mixtures.
  • Two-roll mills capable of precise temperature control, adjustable roll separation, and proper rotation speeds.
  • Plate presses for optional sample pressing to enhance gloss and thickness.

• Quality Assurance Notes
  The standard emphasizes the importance of:

  • Avoiding additional grinding during premixing to prevent altering pigment dispersion.
  • Ensuring thorough mixing during two-roll milling, commonly carried out over 200 roll revolutions within 5-10 minutes.
  • Rapid cooling after pressing to prevent thermal degradation of the specimen.

• Informative Annex
  Annex A provides additional guidance on laboratory practices, impact of pigment carrier materials, and variability accommodation in laboratory apparatus.

Applications

• Pigment Testing in PVC-P
  Enables manufacturers and testing laboratories to prepare specimens for evaluating pigment properties such as color strength, dispersion quality, and stability within plasticized PVC matrices.

• Quality Control in PVC Industry
  Assists in quality assurance workflows by standardizing test specimen preparation, thus supporting accurate comparison of pigment batches or new formulations.

• Research and Development
  Provides a reproducible method for formulating test sheets during pigment innovation, helping to assess compatibility and performance before commercial production.

• Regulatory Compliance
  Supports compliance with European testing standards for pigments and extenders used in flexible PVC products.
