This global GPS standard influences chain links 4, 5 and 6 in all chains of standards. The ISO/GPS Masterplan given
37、 in ISO/TR 14638 gives an overview of the ISO/GPS system of which this document is a part. The fundamental rules of ISO/GPS given in ISO 8015 apply to this document and the default decision rules given in ISO 14253-1 apply to specifications made in accordance with this document, unless otherwise ind
38、icated. For more detailed information on the relation of this International Standard to other standards and to the GPS matrix model, see Annex D. This part of ISO 14253 has been developed to support ISO 14253-1. This part of ISO 14253 establishes a simplified, iterative procedure of the concept and
39、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 the Guide to the expression of uncertainty in measurement (GUM). In most c
40、ases, 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
41、 elaborated procedures of the GUM need to be applied. This simplified, iterative procedure of the GUM methods is intended for GPS measurements, but may be used in other areas of industrial (applied) metrology. The uncertainty of measurement and the concept of handling uncertainty of measurement are
42、important to all the technical functions within a company. This part of ISO 14253 is relevant to several technical functions, including management, design and development, manufacturing, quality assurance and metrology. This part of ISO 14253 is of special importance in relation to ISO 9000 quality
43、assurance systems, e.g. it is a requirement that methods for monitoring and measurement of the quality management system processes are suitable. The measurement uncertainty is a measure of the process suitability. In this part of ISO 14253, the uncertainty of the result of a process of calibration a
44、nd a process of measurement is handled in the same way: calibration is treated as a “measurement of the metrological characteristics of a measuring equipment or a measurement standard”; measurement is treated as a “measurement of the geometrical characteristics of a workpiece”. Therefore, in most ca
45、ses, no distinction is made in the text between measurement and calibration. The term “measurement” is used as a synonym for both. DIN EN ISO 14253-2:2011-11 EN ISO 14253-2:2011 (E) 51 Scope This part of ISO 14253 gives guidance on the implementation of the concept of the “Guide to the estimation of
46、 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 p
47、rovide the basis for international comparison of measurement results and their uncertainties (relationship between purchaser and supplier). This part of ISO 14253 is intended to support ISO 14253-1. Both parts are beneficial to all technical functions in a company in the interpretation of GPS specif
48、ications i.e. tolerances of workpiece characteristics and values of maximum permissible errors (MPEs) for metrological characteristics of measuring equipment. This part of ISO 14253 introduces the Procedure for Uncertainty MAnagement (PUMA), which is a practical, iterative procedure based on the GUM
49、 for estimating uncertainty of measurement without changing the basic concepts of the GUM. It is intended to be used generally for estimating uncertainty of measurement and giving statements of uncertainty for: single measurement results; the comparison of two or more measurement results; the comparison of measurement results from one or more workpieces or pieces of measurement equipment with given specifications i.e. maximum permissible errors (MPEs) for a metrological chara
