Textiles. Tests for colour fastness - Colour fastness to weathering: Outdoor exposure Ingestion-build-135476 Why should you use BS1 Scope This document specifies a method intended for determining the resistance of the colour of textiles of all kinds except loose fibres to the action of weather as determined by outdoor exposure. NOTE General information on colour fastness to light is given in Annex A.
