textiles method of exposure to laboratory light source using a xenon arc lamp

Many textiles can change in colour appearance when then come into contact with and are exposed to direct sunlight for a significant amount of time. ISO 105 B02 standard is the test method of exposing samples to an artificial light source under specified environmental conditions. The colourfastness is then measured by comparison of a reference sample under standard light conditions.

accelerated weathering & lightfastness testing standards

These standards are designed to test your products to the conditions they would be exposed to during their service life, either outdoors or indoors in direct sunlight through window glass.
