Colouring materials in plastics - Determination of colour stability to heat during processing of colouring materials in plastics - Part 3: Determination by oven test

Scope

This part of EN 12877 describes a method for determining the colour stability of colouring materials in plastics under defined conditions by an oven test. The result of the determination is a relative value, not an absolute one. The method is mainly used for testing colouring materials in polyvinyl chloride, and in thermosetting materials.
