ActiveGeometrical Product Specifications(GPS) - Surface texture: Profile method - Surface having stratified functional properties - Part 3: Height characterization using the material probability curve
产品几何技术规范（GPS） 表面结构 轮廓法 具有复合加工特征的表面 第3部分: 用概率支承率曲线表征高度特性
Application Summary AI generated
This standard specifies the method for characterizing the height properties of stratified functional surfaces (such as honed cylinder bores or plateau-honed engine liners) using the material probability curve derived from profile measurements. It is applied in precision manufacturing and quality control to evaluate surface texture parameters that correlate with wear resistance, lubrication retention, and sealing performance. The standard is particularly relevant for automotive, aerospace, and hydraulic component industries where surfaces with distinct functional layers are critical.
