ISO 4288 pdf download.Geometrical Product Specifications (GPS) – Surface texture: Profile method – Rules and procedures for the assessment of surface texture 1 Scope This International Standard specifies the rules for comparison of the measured values with the tolerance limits for surface texture parameters defined in IS0 4287, IS0 12085, IS0 13565-2 and IS0 13565-3. It also specifies the default rules for selection of cut- off wavelength, ilc, for measuring roughness profile parameters according to IS0 4287 by using stylus instruments according to IS0 3274. 2 Normative references The following standards contain provisions which, through reference in this text, constitute provisions of this International Standard.
