Describes the Stuttgart method for determining the wear resistance of the wear layer of polyvinyl chloride floor coverings under laboratory conditions. The method is applicable to polyvinyl chloride 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.
