Measuring methods have been put together that can be used to determine the proportion of the load-bearing area in relation to the reference area. In addition, methods are mentioned that only allow indirect conclusions to be drawn about the surface area, but are used by practitioners because additional information about other characteristic parameters of the surface shape can be determined.*www.vdi.de/2603
