GB/T 16671-2009 Geometrical Product Specifications (GPS)—Geometrical tolerancing—Maximum material requirement (MMR),least material requirement (LMR) and reciprocity requirement (RPR)
Abstract
This standard specifies the terms and definitions of maximum entity requirements, minimum entity requirements, and reversible requirements, as well as basic provisions, drawing representation methods, and application examples.
This standard applies to cases where the dimensions and geometric tolerances of workpieces need to be correlated with each other to meet their special functional requirements, such as ensuring the assemblyability of parts (maximum entity requirements) and guaranteeing minimum wall thickness (minimum entity requirements). However, maximum entity requirements and minimum entity requirements also apply to other functional requirements.
