1 Scope
This standard specifies the rules for comparison of the measured values with the tolerance limits for surface texture parameters defined in GB/T 3505-2009, GB/T 18618, GB/T 18778.2-2003 and GB/T 18778.3-2006.
It also specifies the default rules for selection of cutoff wavelength, λc, for measuring roughness profile parameters according to GB/T 3505-2009 by using stylus instruments according to GB/T 6062.
