BS EN ISO 16610-31:2025 - TC

This standard BS EN ISO 16610-31:2025 - TC Tracked Changes. Geometrical product specifications (GPS). Filtration is classified in these ICS categories:

• 17.040.20 Properties of surfaces
• 17.040.40 Geometrical Product Specification (GPS)

This document specifies robust Gaussian regression filters for the filtration of surface profiles. It defines, in particular, how to separate large- and small-scale lateral components of surface profiles with protruding dales and hills. The concept presented for closed profiles are applicable to the case of roundness filtering. Where appropriate, these concept can be extended to generalized closed profiles, especially for surface profiles with re-entrant features.
