Geometrische Produktspezifikationen (GPS) - Prüfung von Werkstücken und Messgeräten durch Messungen - Teil 2: Leitfaden zur Schätzung der Unsicherheit von GPS-Messungen bei der Kalibrierung von Messgeräten und bei der Produktprüfung (ISO/TS 14253-2:1999)

Diese Technische Spezifikation enthält Leitlinien für die Einführung des Konzepts des "Leitfadens zur Angabe der Unsicherheit beim Messen" (abgekürzt GUM), welcher in der Industrie bei der Kalibrierung von Normalen und Messeinrichtungen im GPS-Bereich und bei der Messung von Werkstück-GPS-Merkmalen angewendet werden soll. Ziel ist es, eine vollständige Information darüber zu geben, wie die Angaben zur Unsicherheit ermittelt werden können, sowie die Schaffung einer Grundlage für den internationalen Vergleich von Messergebnissen und deren Unsicherheit (Beziehung zwischen Abnehmer und Hersteller).
Diese Technische Spezifikation soll ISO 14253-1 unterstützen und ist mit ISO 14253-1 für alle technischen Aufgaben in einem Unternehmen entsprechend der GPS-Spezifikationen (d. h. für Toleranzen der Merkmale von Werkstücken und den Werten der maximal zulässigen Abweichungen (MPE) für messtechnische Merkmale von Messeinrichtungen) nützlich.
Diese Technische Spezifikation führt eine Prozedur für das Unsicherheits-MAnagement - PUMA - ein. Es handelt sich um ein praktisches, iteratives, auf dem GUM basierendes Verfahren zur Schätzung der Unsicherheit ohne Änderung des Grundlagenkonzeptes von GUM und soll allgemein zur Schätzung der Messunsicherheit und zur Angabe der Unsicherheit in folgenden Teilen dienen:
¾ Einzelmessergebnisse,
¾ den Vergleich von zwei oder mehreren Messergebnissen,
¾ den Vergleich von Messergebnissen - eines oder mehrerer Werkstücke oder Messeinrichtungen - mit gegebenen Spezifikationen (d. h. die maximal zulässigen Abweichungen (MPE) eines messtechnischen Merkmals eines Messgerätes oder eines Normals und die Toleranzgrenzen eines Werkstückmerkmals usw.), um Übereinstimmung oder Nichtübereinstimmung mit der Spezifikation festzustellen.

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 3.
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 normative 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 every three years with a view to deciding whether it can be transformed into an
International Standard.
Attention is drawn to the possibility that some of the elements of this Technical Specification may be the subject of
patent rights. ISO shall not be held responsible for identifying any or all such patent rights.

Introduction
This Technical Specification is a global GPS technical report (see ISO/TR 14638:1995). This global GPS Technical
Report influences chain link 4, 5 and 6 in all chains of standards.
For more detailed information of the relation of this report to other standards and the GPS matrix model, see
annex D.
This Technical Specification is developed to support ISO 14253-1. This Technical Specification establishes a
simplified, iterative procedure of the concept and 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 "Guide to the expression of uncertainty in
measurement" (GUM). In most cases 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
elaborated procedures of the GUM must be applied.
This simplified, iterative procedure of t
