ISO 23232:2009提供了水性耐污性指南。它可以提供水性耐污性的粗略指标，因为通常，水性液体排斥等级越高，对水/醇基材料，尤其是水/醇基液体的耐污性越好。当比较给定基材的各种饰面时尤其如此。ISO 23232:2009也可用于确定洗涤和/或干洗处理是否对基材的水性液体排斥特性具有任何不利影响。为此，建议使用ISO 6330或ISO 3175中描述的洗涤和/或干洗处理程序。 ISO 23232:2009并不旨在给出基材对水/醇染色的抗性的绝对测量值。基物质。其他因素，如水/醇基物质的组成和粘度、基材结构、纤维类型、染料和其他整理剂也影响耐污性。 SO 23232:2009不旨在估计基底对水/醇基化学品渗透的抵抗力；有关该评估，请参见ISO 6530。

ISO 23232:2009 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. ISO 23232:2009 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. ISO 23232:2009 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. _{SO 23232:2009 is not intended to estimate the resistance to penetration of the substrate by water/alcohol-based chemicals; for this evaluation, see ISO 6530.}
