What Is Artificial Daylight Stability?
Artificial Daylight Stability Testing evaluates how materials, products, or coatings respond to simulated daylight exposure over time. It helps determine resistance to fading, discoloration, and degradation when exposed to controlled light sources that replicate natural sunlight conditions.
This testing is widely used in textiles, plastics, paints, and coatings industries to assess colorfastness and durability. By simulating long-term light exposure in a controlled environment, it enables manufacturers to predict product lifespan and ensure compliance with quality and performance standards.

Our Testing Procedure
Sample Preparation
Samples are conditioned and mounted for uniform exposure to artificial daylight.
1Exposure Setup
Samples are placed in a light exposure chamber with controlled intensity and conditions.
2Light Exposure
Materials are exposed to simulated daylight for a specified duration.
3Evaluation
Changes in color or properties are assessed and compared with standards.

Artificial Daylight Stability FAQs
Artificial daylight stability testing evaluates how materials respond to simulated sunlight exposure. It measures fading, discoloration, and degradation under controlled light conditions to predict long-term performance and durability of products.
This testing is important because exposure to sunlight can degrade materials over time. It helps manufacturers ensure products maintain color, strength, and appearance throughout their intended lifespan.
Factors include light intensity, exposure duration, temperature, humidity, and sample properties. Proper control of these parameters ensures accurate and repeatable results.
Color change is measured using grey scale ratings or spectrophotometers. These methods provide visual and quantitative assessment of fading and discoloration after exposure.
Materials such as textiles, plastics, paints, coatings, and pigments can be tested. These materials are often exposed to light and require evaluation for color stability and durability.
