ISO 105 B02 : Textile & Inks Accelerated Weathering Standards

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

Many textiles can change in colour appearance when they 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.
