The aim is to promote full information on how to achieve uncertainty statements and provide the basis for international comparison of measurement results and their uncertainties (relationship between purchaser and supplier).<\/p>\n<p>This part of ISO&nbsp;14253 is intended to support ISO&nbsp;14253-1. Both parts are beneficial to all technical functions in a company in the interpretation of GPS specifications [i.e. tolerances of workpiece characteristics and values of maximum permissible errors (MPEs) for metrological characteristics of measuring equipment].<\/p>\n<p>This part of ISO&nbsp;14253 introduces the Procedure for Uncertainty MAnagement (PUMA), which is a practical, iterative procedure based on the GUM 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:<\/p>\n<ul>\n<li>\n<p>single measurement results;<\/p>\n<\/li>\n<li>\n<p>the comparison of two or more measurement results;<\/p>\n<\/li>\n<li>\n<p>the comparison of measurement results \u2014 from one or more workpieces or pieces of measurement equipment \u2014 with given specifications [i.e. maximum permissible errors (MPEs) for a metrological characteristic of a measurement instrument or measurement standard, and tolerance limits for a workpiece characteristic, etc.], for proving conformance or non-conformance with the specification.<\/p>\n<\/li>\n<\/ul>\n<p>The iterative method is based basically on an upper bound strategy, i.e. overestimation of the uncertainty at all levels, but the iterations control the amount of overestimation. Intentional overestimation \u2014 and not underestimation \u2014 is necessary to prevent wrong decisions based on measurement results. The amount of overestimation is controlled by economical evaluation of the situation.<\/p>\n<p>The iterative method is a tool to maximize profit and minimize cost in the metrological activities of a company. The iterative method\/procedure is economically self-adjusting and is also a tool to change\/reduce existing uncertainty in measurement with the aim of reducing cost in metrology (manufacture). The iterative method makes it possible to compromise between risk, effort and cost in uncertainty estimation and budgeting.<\/p>\n","protected":false},"excerpt":{"rendered":"<p><b>Geometrical product specifications (GPS).
