A.C.T. Colorfastness to Light

How well textiles hold up to light exposure can greatly impact suitability to specific applications.

Colorfastness to Light Testing

Applied Lab offers multiple options for Colorfastness to Light testing based on a product’s application or expected lifecycle. This page addresses the requirements laid out by the Association for Contract Textiles’ Voluntary Performance Guidelines.

Colorfastness to Light testing is an accelerated method that assesses the fabric’s ability to resist fading or other color degradation when exposed to a Xenon Arc light source for a specified amount of time. The light simulates sunlight through window glass. Colorfastness testing is important in determining how well a textile will hold up to sunlight exposure over time.
