Geometrical product specifications (GPS) - Inspection by measurement of workpieces and measuring equipment - Part 4: Background on functional limits and specification limits in decision rules (ISO/TS 14253-4:2010)

ISO 14253-4:2010 outlines the main assumptions behind the theoretically ideal decision rules established in ISO 14253-1. It discusses why these rules have to be the default rules and what considerations should be taken into account before applying different decision rules.
ISO 14253-4:2010 applies to all specifications defined in general GPS standards (see ISO/TR 14638), i.e. standards prepared by ISO/TC 213, including workpiece specifications (usually given as specification limits), and measuring equipment specifications (usually given as maximum permissible errors).

Geometrische Produktspezifikation (GPS) - Prüfung von Werkstücken und Messgeräten durch Messen - Teil 4: Aspekte zur Auswahl von Entscheidungsregeln (ISO/TS 14253-4:2010)

Dieser Teil von ISO 14253 erfasst die wichtigsten Annahmen, die den Hintergrund für die in ISO 14253-1
festgelegten theoretisch idealen Entscheidungsregeln bilden. Es wird erörtert, warum diese Regeln Default-
Regeln sind und welche Betrachtungen angestellt werden sollten, bevor andere Entscheidungsregeln
angewendet werden.
Dieser Teil von ISO 14253 gilt für alle Spezifikationen, die in den allgemeinen GPS Normen definiert sind
(siehe ISO/TR 14638), d. h. Normen, die von ISO/TC 213 erstellt wurden, einschließlich der
⎯ Spezifikationen für Werkstücke (im Allgemeinen als Spezifikationsgrenzen angegeben) und
⎯ Spezifikationen für Messgeräte (im Allgemeinen als maximal zulässige Fehler angegeben).

L'ISO 14253-4:2010 décrit les grandes lignes des principales hypothèses sous-jacentes aux règles de décision théoriquement idéales établies dans l'ISO 14253-1. Elle expose les raisons pour lesquelles ces règles sont celles à utiliser par défaut, ainsi que les considérations à prendre en compte avant d'appliquer d'autres règles de décision.
L'ISO 14253-4:2010 s'applique à toutes les spécifications définies dans les normes GPS générales (voir l'ISO/TR 14638), c'est-à-dire les normes préparées par l'ISO/TC 213, y compris:
les spécifications de pièces (généralement exprimées sous forme de limites de spécification), et
les spécifications d'équipements de mesure (généralement exprimées en erreurs maximales tolérées).

Specifikacija geometrijskih veličin izdelka - Kontrola z merjenjem obdelovancev in merilna oprema - 4. del: Merila za izbiro funkcionalnih omejitev ter omejitev pri odločanju (ISO/TS 14253-4:2010)

Ta del standarda ISO 14253 podaja glavne predpostavke za teoretično idealnimi pravili odločanja, vzpostavljenimi v standardu ISO 14253-1. Opisuje, zakaj so ta pravila privzeta pravila in katere predpostavke se upoštevajo pred uporabo posameznih pravil odločanja. Ta del standarda ISO 14253 velja za vse specifikacije, opredeljene v standardih o splošni specifikaciji geometrijskih veličin izdelka (glejte ISO/TR 14638), tj. standardih, ki jih pripravlja ISO/TC 213, vključno s:
– specifikacijami obdelovancev (običajno podanimi kot specifikacijske mejne vrednosti) in
– specifikacijami merilne opreme (običajno podanimi kot največje število dovoljenih napak).

This Technical Specification (CEN/TS) was approved by CEN on 4 April 2010 for provisional application.

The period of validity of this CEN/TS is limited initially to three years. After two years the members of CEN will be requested to submit their
comments, particularly on the question whether the CEN/TS can be converted into a European Standard.

CEN members are required to announce the existence of this CEN/TS in the same way as for an EN and to make the CEN/TS available
promptly at national level in an appropriate form. It is permissible to keep conflicting national standards in force (in parallel to the CEN/TS)
until the final decision about the possible conversion of the CEN/TS into an EN is reached.

ISO/TS 14253-4:2010(E)
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.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International Standards
adopted by the technical committees are circulated to the member bodies for voting. Publication as an
International Standard requires approval by at least 75 % of the member bodies casting a vote.
In other circumstances, particularly when there is an urgent market requirement for such documents, a
technical committee may decide to publish other types of document:
⎯ an ISO Publicly Available Specification (ISO/PAS) represents an agreement between technical experts in
an ISO working group and is accepted for publication if it is approved by more than 50 % of the members
of the parent committee casting a vote;
⎯ an ISO Technical Specification (ISO/TS) represents an agreement between the members of a technical
committee and is accepted for publication if it is approved by 2/3 of the members of the committee casting
a vote.
An ISO/PAS or ISO/TS is reviewed after three years in order to decide whether it will be confirmed for a
further three years, revised to become an International Standard, or withdrawn. If the ISO/PAS or ISO/TS is
confirmed, it is reviewed again after a further three years, at which time it must either be transformed into an
International Standard or be withdrawn.
Attention is drawn to the possibility that some of the elements of this document may be
