GB/T 16671-2009
AbolishedGeometrical product specifications(GPS) - Geometrical tolerancing - Maximum material requirement（MMR），least material requirement（LMR） and reciprocity requirement（RPR）
产品几何技术规范（GPS） 几何公差 最大实体要求、最小实体要求和可逆要求
Application Summary AI generated
This standard defines the application of maximum material requirement (MMR), least material requirement (LMR), and reciprocity requirement (RPR) within geometrical tolerancing for mechanical parts. It is applied in manufacturing and quality inspection to control the functional fit and strength of components, particularly for assembly interfaces like holes and shafts where material condition affects interchangeability. The standard ensures consistent interpretation of tolerances in design, production, and verification across industries such as automotive, aerospace, and precision engineering.
