Colouring materials in plastics - Determination of colour stability to heat during processing of colouring materials in plastics - Part 2: Determination by injection moulding
This part of EN 12877 describes a method for determining the colour stability of colouring materials under defined conditions in plastics by injection moulding. The result of the determination is a relative value, not an absolute one. The method is applicable for testing colouring materials in thermoplastics that are processible by injection moulding.
