ISO 23232:2009
Scope
This International Standard provides a guide for aqueous stain resistance. It can provide a rough index of
aqueous stain resistance as, generally, the higher the aqueous liquid repellency grade, the better the
resistance to staining by water/alcohol-based materials, especially water/alcohol-based liquids. This is
particularly true when comparing various finishes for a given substrate. This International Standard can also
be utilized for 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-based substances. Other factors, such as the composition and viscosity of the
water/alcohol-based 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.
