ISO/TS 14253-2, Geometrical Product Specifications (GPS)--Inspection by measurement of workpieces and measuring equipment

摘要

This Technical Specification gives guidance on the implementation of the concept of Guide to the estimation of uncertainty in measurement (in short GUM) to be applied in industry for the calibration of (measurement) standards and measuring equipment in the field of GPS and the measurement of workpiece GPS-characteristics. The aim is to promote full information on how to achieve uncertainty statements and provide the basis for international comparison of results of measurements and their uncertainties (relationship between purchaser and supplier).This Technical Specification is developed to support ISO 14253-1. This Technical Specification established a simplified, iterative procedure of the concept and the way to evaluate and determine uncertainty (standard uncertainty and expanded uncertainty) of measurement, and the recommendations of the format to document and report the uncertainty of measurement information as given in Guide to the expression of uncertainty in measurement (GUM). In most cases only very limited resources are necessary to estimate uncertainty of measurement by this simplified, iterative procedure, but the procedure may lead to a slight overestimation of the uncertainty of measurement. If a more accurate estimation of the uncertainty of measurement is needed, the more elaborated procedures of the GUM must be applied.
