Colouring materials in plastics - Determination of colour stability to heat during processing of colouring materials in plastics - Part 1: General introduction

This part of EN 12877 gives a general introduction to the most widely used methods for determination of colour stability during processing of colouring materials in plastics under the influence of heat. It also specifies those details which are common to the various test methods described in subsequent Parts of EN 12877. The choice of the test method depends on the plastics material to be coloured, the method of processing and the end-use requirements.

Overview

EN 12877-1:1999 - Colouring materials in plastics: Determination of colour stability to heat during processing - Part 1: General introduction is a CEN standard that provides a general introduction to the principal methods used to assess the colour stability of colouring materials when exposed to heat during plastics processing. This Part defines the common principles, terminology and details that apply across the different test methods described in subsequent parts of EN 12877. The choice of a specific test method depends on the polymer, the processing route and end‑use requirements.

Key topics

• Scope and purpose: Clarifies the objective of assessing colour change of pigments, dyes and masterbatches under processing temperatures and conditions.
• Common test framework: Describes the aspects that are common to the various test methods (e.g., sampling, specimen preparation, conditioning and reporting requirements).
• Selection criteria: Explains how to choose a suitable test method based on the type of plastic, processing technique and performance needs.
• Evaluation principles: Sets out general approaches for measuring and reporting colour change and stability during thermal processing, ensuring consistency between laboratories.
• Terminology and definitions: Standardises key terms used across EN 12877 series to avoid ambiguity in test interpretation and results comparison.

Applications

EN 12877-1 is practical for organizations that need reliable data on how colouring materials behave under processing heat. Typical users include:

• Pigment and dye manufacturers assessing thermal robustness of products.
• Masterbatch and compound producers validating colour performance during extrusion, injection moulding or other processing methods.
• Plastics processors selecting colouring systems for specific production parameters and end‑use specifications.
• Quality control and testing laboratories implementing harmonised test protocols and reporting.
• R&D teams developing heat-stable colour systems and troubleshooting production colour shifts.

Benefits of using this standard include improved colour consistency, reduced production defects, better supplier specifications, and clearer communication of colour stability expectations across the supply chain.

Related standards

• Subsequent parts of the EN 12877 series (method-specific parts) that give the detailed test procedures for particular plastics and processing routes.
• National adoptions (e.g., SIST EN 12877-1:2001) and CEN publications on auxiliary materials and additives for plastics (ICS: 83.040.30).

Keywords: EN 12877-1, colour stability, colouring materials in plastics, heat stability, colourfastness during processing, CEN standard, pigment testing, masterbatch testing.
