本欧洲标准规定了多孔无机材料上防水产品性能的实验室评估方法。 它是基于测量几个参数，使用标准测试方法在老化前后评估产品的性能。 在实验室内可接受的表现并不构成对每种情况的一致认可。遗产对象的特殊背景，包括材料指定，条件，曝光，盐含量和与入水有关的问题等因素需要进一步调查

This European Standard specifies the methodology for laboratory evaluation of the performance of water repellent products on porous inorganic materials. It is based on the measurement of several parameters which assess the performance of the product using standard test methods before and after ageing. Acceptable performance within the laboratory does not constitute a blanket endorsement of application in every situation. The particular context of the heritage object, including such factors as material designation, condition, exposure, salt content and problems related to water ingress requires further investigation.
