Geometrical product specification (GPS) — Surface texture: Areal — Part 74: Software measurement standards

Scope

This document defines Type F1, Type F2 and Type F3 software measurement standards, for verifying instruments and analysis software. It introduces the concept of mathematical softgauge (Type F3) that is based upon mathematics and is independent from implementation arbitrary choices. Type F1 traceable softgauges and Type F2 traceable software are derived from the Type F3 mathematical softgauges.
