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

Scope

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.
