Geometrical product specifications (GPS) - Geometrical tolerancing - Maximum material requirement (MMR), least material requirement (LMR) and reciprocity requirement (RPR) (ISO 2692:2014)
ISO 2692:2014 defines the maximum material requirement, the least material requirement and the reciprocity requirement. These requirements can only be applied to features of size.
These requirements are used to control specific functions of workpieces where size and geometry are interdependent, e.g. to fulfil the functions "assembly of parts" (for maximum material requirement) or "minimum wall thickness" (for least material requirement). However, the maximum material requirement and least material requirement are also used to fulfil other functional design requirements.
Considering this interdependence between size and geometry, the principle of independency defined in ISO 8015 does not apply when the maximum material requirement, least material requirement, or reciprocity requirement, are used.
Geometrische Produktspezifikation (GPS) - Geometrische Tolerierung - Maximum-Material-Bedingung (MMR), Minimum-Material-Bedingung (LMR) und Reziprozitätsbedingung (RPR) (ISO 2692:2014)
Diese Internationale Norm legt die Maximum-Material-Bedingung, die Minimum-Material-Bedingung und die Reziprozitätsbedingung fest. Diese Anforderungen können ausschließlich auf Größenmaßelemente angewendet werden.
Diese Anforderungen dienen zur Steuerung bestimmter Funktionen von Werkstücken, bei denen eine Abhängigkeit von Größenmaß und Geometrie vorhanden ist, z. B. zur Erfüllung der Funktionen "Fügbarkeit von Teilen" (für die Maximum-Material-Bedingung) oder "Mindestwandstärke" (für die Minimum-Material-Bedingung). Die Maximum-Material-Bedingung und die Minimum-Material-Bedingung werden jedoch auch zur Erfüllung sonstiger funktionaler Konstruktionsanforderungen genutzt.
Unter Berücksichtigung dieser gegenseitigen Abhängigkeit von Größenmaß und Geometrie, gilt das in ISO 8015 festgelegte Unabhängigkeitsprinzip nicht, wenn die Maximum-Material-Bedingung, die Minimum-Material-Bedingung oder die Reziprozitätsbedingung angewendet werden.
Spécification géométrique des produits (GPS) - Tolérancement géométrique - Exigence du maximum de matière (MMR), exigence du minimum de matière (LMR) et exigence de réciprocité (RPR) (ISO 2692:2014)
L'ISO 2692:2014 définit l'exigence du maximum de matière, l'exigence du minimum de matière et l'exigence de réciprocité. Ces exigences ne s'appliquent qu'aux entités dimensionnelles.
L'objectif de ces exigences est de contrôler des fonctions spécifiques des pièces où la taille et la géométrie sont interdépendantes, afin d'assurer, par exemple, l'assemblage des pièces (dans le cas de l'exigence du maximum de matière) ou une épaisseur minimale de paroi (dans le cas de l'exigence du minimum de matière). Cependant, l'exigence du maximum de matière et l'exigence du minimum de matière peuvent également être employées pour respecter d'autres exigences fonctionnelles de conception.
Considérant cette interdépendance entre la taille et la géométrie, le principe d'indépendance défini dans l'ISO 8015 ne s'applique pas lorsque l'exigence du maximum de matière, l'exigence du minimum de matière ou l'exigence de réciprocité sont employés.
Specifikacija geometrijskih veličin izdelka (GPS) - Toleriranje geometrijskih veličin - Zahteva po maksimalnem materialu, zahteva po minimalnem materialu in zahteva po usklajenosti materialov (ISO 2692:2014)
Ta mednarodni standard določa zahtevo po maksimalnem materialu, zahtevo po minimalnem materialu in zahtevo po usklajenosti materialov. Te zahteve je mogoče uporabiti le za lastnosti velikosti.
Te zahteve se uporabljajo za kontrolo posebnih lastnosti obdelovancev, kadar sta velikost in geometrija odvisni druga od druge, npr. za izpolnitev namena »sestavljanja delov« (za zahtevo po maksimalnem materialu) ali »največje debeline zidu« (za zahtevo po minimalnem materialu). Zahteva po maksimalnem materialu in zahteva po minimalnem materialu se lahko uporabljata tudi za izpolnitev drugih zahtev po funkcionalni zasnovi.
Glede na medsebojno odvisnost med velikostjo in geometrijo se načelo medsebojne odvisnosti iz standarda ISO 8015 ne uporablja, kadar se uporabi zahteva po maksimalnem materialu, zahteva po minimalnem materialu ali zahteva po usklajenosti materialov.

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

Introduction
0.1. General
This International Standard is a geometrical product specification (GPS) standard and is to be regarded
as a general GPS standard (see ISO/TR 14638). It influences the chain links 1, 2 and 3 of the chain of
standards on size of linear “features of size” and form of a line (independent/dependent of a datum),
form of a surface (independent/dependent of a datum), orientation and location of derived features
based on “features of size” and datums also based on “features of size”.
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 ISO 14253-1 apply to specifications made in accordance with this
document, unless otherwise indicated.
For more detailed information on the relation of this International Standard to the GPS matrix model,
see Annex C.
This International Standard covers some frequently occurring workpiece functional cases in design
and tolerancing. The “maximum material requirement”, MMR, covers “assembleability” and the “least
material requirement”, LMR, covers, for example, “minimum wall thickness” of a part. Each requirement
(MMR and LMR) combines two independent requirements into one collective requirement, which more
accurately simulates the intended function of the workpiece. In some cases of both MMR and LMR, the
“reciprocity requirement”, RPR, can be added.
NOTE In ISO GPS standards, threaded features are often considered as features of size of type cylinder.
However, no rules are defined in this International Standard for how to apply MMR, LMR and RPR to threaded
features. Consequently, the tools defined in this International Standard cannot be used for threaded features.
