Abstract: Filtration is required at several reasons in the process of surface texture analysis. The main reason for using a filter is to separate long-scale components from short-scale components. Filtration techniques are used in surface metrology to separate the roughness component from the waviness component and the form component to calculate parameters according to international standards. Paper described problems roughness and wavering of profiles and surface area with a comprehensive reference to the relevant international standards.

Keywords: Filtration, Surface texture, Roughness, Waviness.
