This standard describes a method for determining the color fastness on textiles, of any nature and in all their transformation phases, subjected to the action of formaldehyde vapor (for example how they can be found when they are stored with articles that have undergone an anti-creasing treatment, a permanent sizing treatment, etc., or which is used for the post-dyeing treatment).
