This document specifies an instrumental method for determining the yellowness index and change in yellowness index on clear, translucent, or opaque plastics. NOTE Change in yellowness index is often used to evaluate the effect of environment, e.g. heat, UV exposure, etc., on colour stability.
Abstract
Overview
is an internationally recognized standard developed by ISO. This standard outlines an instrumental method for evaluating the yellowness index and changes in the yellowness index in clear, translucent, or opaque plastics. The standard is particularly valuable for assessing how environmental factors, such as heat and UV exposure, impact the colour stability of plastic materials. Adhering to ISO 17223:2026 helps manufacturers and laboratories ensure consistent, reliable, and comparable results when measuring and reporting color changes in plastics.
