This European Standard describes the Frick-Taber method for determining the wear resistance of the wear layer of polyvinyl chloride floor coverings under laboratory conditions. The test method is applicable to floor coverings with smooth surfaces. It can be used to determine the wear resistance of surfaces against abrasion and particularly for ranking different wear layer types within one type of product. It is not appropriate for comparing the wear resistance of different materials, e.g. rubber and polyvinyl chloride.Wear resistance of PVC floor coverings is measured by an apparatus with abrading wheels. Results are expressed as volume lost.<\/p>\n
