Geometrical product specifications (GPS) – Geometrical tolerancing – Maximum material requirement (MMR), least material requirement (LMR) and reciprocity requirement (RPR) (ISO/DIS 2692:2019)

Scope

This document defines the maximum material requirement, the least material requirement and the
reciprocity requirement. These requirements can only be applied to linear features of size of cylindrical
type or opposed planar type.
These requirements are often 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 can also be used to fulfil other functional design
requirements.
