Abstract
Overview
ISO 12781-1:2011 - "Geometrical product specifications (GPS) - Flatness - Part 1: Vocabulary and parameters of flatness" - defines the terms, concepts and parameters used to describe of individual complete integral features. It is a general GPS standard that focuses on the vocabulary and measurable parameters for flatness (not on the full specification operators - see Part 2). The standard covers digital “extracted surfaces,” the effect of filters on a flatness surface, and reference-plane conventions used when reporting flatness measurements.
