Understanding MMR, LMR, and RPR

The Maximum Material Requirement (MMR) is a critical concept in geometrical tolerancing that ensures the functionality of a part by specifying the maximum material condition. This requirement is essential for maintaining the integrity and performance of components under various conditions.

The Least Material Requirement (LMR) is equally important, focusing on the minimum material condition. This requirement is vital for ensuring that parts do not become too thin or weak, which could compromise their structural integrity and functionality.

The Reciprocity Requirement (RPR) is a unique aspect of this standard, providing guidelines for the reciprocal relationship between MMR and LMR. This requirement ensures that the balance between maximum and minimum material conditions is maintained, optimizing the performance and reliability of the product.

BS EN ISO 2692:2021

This standard BS EN ISO 2692:2021 Geometrical product specifications (GPS). Geometrical tolerancing. Maximum material requirement (MMR), least material requirement (LMR) and reciprocity requirement (RPR) is classified in these ICS categories:

• 17.040.40 Geometrical Product Specification (GPS)
• 01.100.20 Mechanical engineering drawings

This document defines the maximum material requirement (MMR), the least material requirement (LMR) and the reciprocity requirement (RPR). These requirements can only be applied to linear features of size of cylindrical type or two parallel opposite planes type.

These requirements are often used to control specific functions of workpieces where size and geometry are interdependent, for example to fulfil the functions “assembly of parts” (for MMR) or “ minimum wall thickness” (for LMR). However, the MMR and LMR can also be used to fulfil other functional design requirements.
