Application Summary AI generated

This standard specifies the method for characterizing the height properties of surfaces with stratified functional properties, such as those produced by plateau honing or lapping, using a linearized material ratio curve. It is applied in the automotive and manufacturing industries to evaluate the wear and lubrication performance of engine cylinder bores, bearing surfaces, and other precision components. The standard provides a quantitative basis for quality control in production and acceptance testing of surfaces requiring specific functional behavior under load.
