The ISO 105-B10:2014 standard specifies a test method for the weathering colour fastness of Spinning & weaving products under artificial efflorescence conditions. Spinning & weaving products are tested by simulating the solar Light spectrum in a Xenon-arc radiator, combining the action of liquid water and water vapor. This method is used to evaluate the Color variation and aging behavior that Spinning & weaving products may encounter in an outdoor environment. Unlike ISO 105-B04, this part of the standard provides another testing option, not as a replacement for the former, but as a supplement. The test is applied to a variety of Spinning & weaving products, including white Spinning & weaving products, to determine their durability and aging behavior.
