ISO 13565-1:1996 – GPS — Surface texture: Profile method; Surfaces having stratified functional properties — Part 1: Filtering and general measurement conditions
Topic: Surface Roughness
Primary Standard: ISO
Scope
This part of ISO 13565 describes a filtering method for use with surfaces that have deep valleys below a more finely finished plateau with a relatively small amount of waviness. The reference line resulting from filtering according to ISO 11562 for such surfaces is undesirably influenced by the presence of the valleys. The filtering approach described in this standard suppresses the valley influence on the reference line such that a more satisfactory reference line is generated.
