Geometrical product specifications (GPS) - Inspection by measurement of workpieces and measuring equipment - Part 1: Decision rules for proving conformity or nonconformity with specification (ISO 14253-1:2013)

ISO 14253-1:2013 establishes the rules for determining the conformity or nonconformity with a given tolerance for a characteristic of a workpiece (or a population of workpieces) or limits of maximum permissible errors for a metrological characteristic of a measuring equipment, taking into account the measurement uncertainty.
These rules are different for tolerances to individual workpieces and tolerances to workpiece populations.
It also gives rules on how to deal with cases where a clear decision (conformity or nonconformity with specification) cannot be taken, i.e. when the measurement result falls within the uncertainty range that exists around the specification limits.
ISO 14253-1:2013 applies to specifications defined in general GPS standards (see ISO/TR 14538), i.e. standards prepared by ISO/TC 213, including:
? workpiece/population of workpieces specifications (usually given as an upper tolerance limit or a lower tolerance limit or both), and;
? measuring equipment specifications (usually given as maximum permissible errors).
ISO 14253-1:2013 only applies for characteristics expressed as numerical quantity values.

Geometrische Produktspezifikationen (GPS) - Prüfung von Werkstücken und Meßgeräten durch Messen - Teil 1: Entscheidungsregeln für den Nachweis von Konformität oder Nichtkonformität mit Spezifikationen (ISO 14253-1:2013)

Dieser Teil von ISO 14253 legt Regeln für die Entscheidung der Konformität oder Nichtkonformität mit einer vorgegebenen Toleranz für ein Werkstück (oder eine Population von Werkstücken) oder Grenzabweichungen (für ein Messgerät) unter Berücksichtigung der Messunsicherheit fest.
Diese Regeln sind unterschiedlich für die Toleranzen einzelner Werkstücke und Toleranzen einer Werkstückpopulation.
Er legt außerdem die Verfahrensweise für die Fälle fest, für die keine klare Entscheidung (Konformität oder Nichtkonformität mit der Spezifikation) getroffen werden kann, d. h. wenn die Messergebnisse in den Unsicherheitsbereich (siehe 3.23) fallen, der um die Spezifikationsgrenzen herum existiert.
Dieser Teil von ISO 14253 gilt für Spezifikationen in allgemeinen GPS-Normen (siehe ISO/TR 14638), die vom ISO/TC 213 erarbeitet wurden, einschließlich:
-   Spezifikationen für Werkstücke/für die Population von Werkstücken (üblicherweise als eine obere Toleranzgrenze oder eine untere Toleranzgrenze oder beides angegeben), und;
-   Spezifikationen für Messgeräte (üblicherweise als maximal zulässige Fehlergrenze angegeben).
Dieser Teil von ISO 14253 gilt nur für Merkmale mit variablen Größenwerten.

Spécification géométrique des produits (GPS) - Vérification par la mesure des pièces et des équipements de mesure - Partie 1: Règles de décision pour prouver la conformité ou la non-conformité à la spécification (ISO 14253-1:2013)

L'ISO 14253-1:2013 établit les règles permettant de déterminer la conformité ou la non-conformité à une tolérance donnée pour une caractéristique d'une pièce (ou une population de pièces) ou aux limites des erreurs maximales tolérées pour une caractéristique métrologique d'un équipement de mesure, en prenant en compte l'incertitude de mesure.
Ces règles sont différentes pour des tolérances de pièces individuelles et des tolérences de populations de pièces.
Elle donne aussi des règles pour les cas où une décision claire (conformité ou non-conformité à la spécification) ne peut pas être prise, c'est-à-dire lorsque le résultat de mesure se trouve dans la plage d'incertitude qui se situe autour des limites de spécification.
L'ISO 14253-1:2013 est applicable aux spécifications définies dans les normes générales GPS (voir l'ISO/TR 14638), c'est-à-dire les normes élaborées par l'ISO/TC 213, comprenant
- les spécifications des pièces/populations de pièces (généralement exprimées sous forme de limites de tolérance), et
- les spécifications des équipements de mesure (généralement exprimées sous forme d'erreurs maximales tolérées).
L'ISO 14253-1:2013 s'applique uniquement aux caractéristiques exprimées sous forme de valeurs numériques.
L'ISO 14253-1:2013 ne s'applique pas à la vérification utilisant des calibres à limites. La vérification avec calibres à limites est couverte par l'ISO 1938-1.

Specifikacija geometrijskih veličin izdelka (GPS) - Preverjanje z merjenjem obdelovancev in merilne opreme - 1. del: Pravila odločanja za potrjevanje skladnosti ali neskladnosti s specifikacijo (ISO 14253-1:2013)

Ta del standarda ISO 14253 določa pravila za ugotavljanje skladnosti ali neskladnosti podane tolerance za značilnost obdelovanca (ali skupine obdelovancev) ali omejitve največjega števila dovoljenih napak za meroslovne značilnosti opreme za merjenje z upoštevanjem merilne negotovosti. Та pravila se razlikujejo za tolerance posameznih obdelovancev in tolerance skupin obdelovancev. Podaja tudi pravila za ravnanje v primerih, ko jasna odločitev (skladnost ali neskladnost s specifikacijo) ni mogoča, tj. ko je rezultat merjenja znotraj nedoločljivega razpona (glejte 3.23) okoli omejitev specifikacije. Ta del standarda ISO 14253 velja za specifikacije, opredeljene v splošnih standardih o specifikaciji geometrijskih veličin izdelka (glejte ISO/TR 14638), tj. standardih, ki jih pripravlja ISO/TC 213, vključno s: – specifikacijami obdelovancev/skupine obdelovancev (običajno podanimi kot zgornja tolerančna meja ali spodnja tolerančna meja ali oboje) in – specifikacijami merilne opreme (običajno podanimi kot največje število dovoljenih napak). Ta del standarda ISO 14253 velja samo za značilnosti, izražene kot numerične vrednosti količine.

ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out
through ISO technical committees. Each member body interested in a subject for which a technical
committee has been established has the right to be represented on that committee. International
organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.
ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of
electrotechnical standardization.

ISO 14253-1:2013(E)
Introduction
This part of ISO 14253 is a geometrical product specifications (GPS) standard and is to be regarded as a
global GPS standard (see ISO/TR 14638). It influences the chain links 4, 5 and 6 of all chains of general
GPS standards.
The ISO/GPS Masterplan given 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 this document apply in ISO/GPS, unless otherwise indicated.
For more detailed information on the relation of this part of ISO 14253 to other standards and the GPS
matrix model, see Annex A.
The estimated measurement uncertainty is to be taken into account when providing evidence for
conformity or nonconformity with specification.
The problem arises when a measurement result falls close to the upper or lower specification limit. In this
case it is not possible to prove conformity or nonconformity with specifications, since the measurement
result plus or minus the expanded measurement uncertainty includes one of the specification limits.
Therefore, a supplier/customer agreement should be foreseen in order to solve the problems which
could arise. This part of ISO 14253 explains how to handle specification and measurement uncertainty
and establishes decision rules for proving conformity or nonconformity with specification.
