Geometrical Product Specifications (GPS) -- Surface texture: Profile method; Surfaces having stratified functional properties -- Part 1: Filtering and general measurement conditions
This standard was last reviewed and confirmed in 2017. Therefore this version remains current.
Decribes a filtering method for use with surfaces having stratified functional properties. The surfaces have a relatively small amount of waviness. This filtering method suppresses the valley influence on the reference line such that a more satisfactory line is generated.
