Defines rules for comparing measured values with tolerance limits for surface texture parameters as in ISO 4287, ISO 12085, ISO 13565-2 and ISO 13565-3. Also defines default rules for selecting cut-off wavelengths lc for measurement of roughness profile parameters as in ISO 4287, by use of stylus instruments as in ISO 3274.
