Colour fastness to artificial light according to SS-EN ISO 105-B02
This standard describes a method for determining the impact of light on colors in textile materials of all kinds.
The purpose with this method is to determine the colour fastness to light of textiles and how much they fade and change hue over time.
Textile materials are exposed to varying degrees of light damage, both visible light and UV light. By testing the color fastness to light, one can quickly check if the wrong dyes have been used. Testing at an early stage can help avoid complaints.
Colour fastness to artificial light according to SS-EN ISO 105-B02
Exposure is performed in an apparatus producing artificial light corresponding to sunlight through window glass.
The most common way to assess color fastness is to expose reference fabrics with known color fastness in parallel with the test material. These fabrics are graded from 1 to 8 where 8 is the best.
The result of the exposure is the reference number (1-8) whose color change corresponds to the color change of the test material.
Alternatively, one can expose a known sample i parallel with the test material and assess wheather the test material is equally good. A
It is also possible to expose a certain time or amount of light and evaluate the color change against a grayscale with a scale from 1 to 5 where 5 is the best.
