Geometrical product specifications (GPS) - Inspection by measurement of workpieces and measuring equipment - Part 1: Decision rules for verifying conformity or nonconformity with specifications (ISO 14253-1:2017)

ISO 14253-1:2017 establishes the rules for verifying the conformity or nonconformity with a given tolerance for a characteristic of a workpiece (or a population of workpieces) or with a given maximum permissible errors for a metrological characteristic of a measuring equipment, including when the measured value falls close to the specification limits, taking measurement uncertainty into account.
ISO 14253-1:2017 applies to specifications defined in general GPS standards (see ISO 14638), i.e. standards prepared by ISO/TC 213, including:
-      workpiece specifications and population specifications (usually given as an upper specification limit or a lower specification limit or both);
-      measuring equipment specifications (usually given as maximum permissible errors).
ISO 14253-1:2017 only applies for characteristics and maximum permissible errors expressed as 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 14253-1:2017)

Dieses Dokument legt Regeln für die Prüfung der Konformität oder Nichtkonformität mit einer vorgegebenen Toleranz für das Merkmal eines Werkstücks (oder eine Population von Werkstücken) oder mit den Grenzwerten für Messabweichungen für ein messtechnisches Merkmal eines Messmittels, auch wenn sich der Messwert unter Berücksichtigung der Messunsicherheit sehr nahe an einem der Grenzwerte der Spezifikation befindet.
Dieses Dokument gilt für Spezifikationen in allgemeinen GPS-Normen (siehe ISO 14638), die vom ISO/TC 213 erarbeitet wurden, einschließlich:
- Spezifikationen für Werkstücke und für die Population von Werkstücken (üblicherweise als eine obere Spezifikationsgrenze oder eine untere Spezifikationsgrenze oder beides angegeben);
- Spezifikationen für Messgeräte (üblicherweise als maximal zulässige Messabweichungen angegeben).
Dieses Dokument gilt nur für Merkmale und maximal zulässige Messabweichungen, die als Größenwerte angegeben werden.

Spécification géométrique des produits (GPS) - Vérification par la mesure des pièces et des équipements de mesure - Partie 1: Règles de décision pour contrôler la conformité ou la non-conformité à la spécification (ISO 14253-1:2017)

L'ISO 14253-1 :2017 établit les règles permettant de contrôler la conformité ou la non-conformité à une tolérance donnée pour une caractéristique d'une pièce (ou d'une population de pièces) ou à des erreurs maximales tolérées données pour une caractéristique métrologique d'un équipement de mesure, y compris lorsque la valeur mesurée est proche des limites de spécification, en prenant en compte l'incertitude de mesure.
L'ISO 14253-1 :2017 s'applique aux spécifications définies dans les normes générales GPS (voir l'ISO 14638), c'est-à-dire les normes élaborées par l'ISO/TC 213, comprenant:
-      les spécifications de pièces et les spécifications de population (généralement exprimées sous forme de limite de spécification supérieure, ou de limite de spécification inférieure, ou les deux);
-      les spécifications des équipements de mesure (généralement exprimées sous forme d'erreurs maximales tolérées).
L'ISO 14253-1 :2017 s'applique uniquement aux caractéristiques et aux erreurs maximales tolérées exprimées sous forme de valeurs de grandeurs.

Specifikacija geometrijskih veličin izdelka (GPS) - Preverjanje z merjenjem obdelovancev in z merilno opremo - 1. del: Pravila odločanja za potrjevanje skladnosti ali neskladnosti s specifikacijo (ISO 14253-1:2017)

Ta dokument določa pravila za preverjanje skladnosti ali neskladnosti s podano toleranco za značilnost obdelovanca (ali skupine obdelovancev) ali podanimi največjimi dovoljenimi napakami za meroslovne značilnosti opreme za merjenje, vključno s primeri, ko je izmerjena vrednost blizu omejitev iz specifikacije, pri čemer se upošteva merilna negotovost.
Ta dokument se uporablja za specifikacije, opredeljene v splošnih standardih o specifikaciji geometrijskih veličin proizvoda (glej ISO 14638), tj. standardih, ki jih pripravlja ISO/TC 213, vključno s:
– specifikacijami obdelovanca in populacije (običajno podanimi kot zgornja meja, spodnja meja ali oboje),
– specifikacijami merilne opreme (običajno podanimi kot največje dovoljene napake).
Ta dokument se uporablja za lastnosti in največje dovoljene napake, ki so izražene kot količine/vrednosti.

Foreword
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.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of
any patent rights identified during the development of the document will be in the Introduction and/or
on the ISO list of patent declarations received (see www.iso.org/patents).
Any trade name used in this document is information given for the convenience of users and does not
constitute an endorsement.
For an explanation on the voluntary nature of standards, the meaning of ISO specific terms and
expressions related to conformity assessment, as well as information about ISO's adherence to the
World Trade Organization (WTO) principles in the Technical Barriers to Trade (TBT) see the following
URL: www.iso.org/iso/foreword.html.
This document was prepared by Technical Committee ISO/TC 213, Dimensional and geometrical product
specifications and verification, in collaboration with Technical Committee CEN/TC 290, Dimensional and
geometrical product specification and verification.
This third edition cancels and replaces the second edition (ISO 14253-1:2013), which has been
technically revised with the following changes:
— The content applies ISO/IEC Guide 98-4 and gives recommendation for simplification by using
intervals representing the underlying probability. As a consequence, the default coverage factor
k = 2 has been replaced with a default conformance probability of 95 %. This makes the risk constant,
regardless of the relationship between the specification interval and the measurement uncertainty.
See Annex A for additional information.
— Some terminology has been updated.
— The explanation for the population specification modifier has been removed and can now be found
in ISO 18391.
A list of all parts in the ISO 14253 series can be found on the ISO website.
