DANSK DS/ISO 23232 PDF

This international standard is intended to provide a guide to aqueous stain resistance. It can provide a rough index of aqueous stain resistance as generally the higher the aqueous liquid repellency grade the better resistance to staining by water/alcohol materials especially water/alcohol liquids. This is particularly true when comparing various finishes for a given substrate. This international standard can also be utilized in determining if washing and/or dry cleaning treatments have any adverse effects on the aqueous liquid repellency characteristics of a substrate. It is recommended that the washing and/or dry cleaning treatment procedures described in ISO 6330 or ISO 3175 be used for this purpose. This international standard is not intended to give an absolute measure of the resistance of the substrate to staining by water/alcohol substances. Other factors, such as composition and viscosity of the water/alcohol substances, substrate construction, fibre type, dyes and other finishing agents also influence stain resistance. This international standard is not intended to estimate the resistance to penetration of the substrate by water/alcohol based chemicals; for this evaluation see ISO 6530, Protective Clothing - Protection against liquid chemicals - determination of resistance of materials to penetration by liquids.
