The slipperiness is very important characteristic of ceramic floors. So, it is important to establish the estimating method for not only the initial slipperiness but the changing of slipperiness of ceramic floors due to abrasion. In this study the relation between the slipperiness and the surface roughness was investigated. Resulting in, the corelation between the surface roughness (Rpk) and the slip resistance (C.S.R) was cleared. And the abrasion testing machine was developed for the purpose of estimate the changing of slipperiness due to abrasion by means of Rpk and C.S.R.
