ActiveGeometrical product specifications (GPS)—ISO code system for tolerances on linear sizes—Part 2: Tables of standard tolerance classes and limit deviations for holes and shafts
产品几何技术规范（GPS） 线性尺寸公差ISO代号体系 第2部分：标准公差带代号和孔、轴的极限偏差表
Application Summary AI generated
This standard provides standardized tables of tolerance classes and limit deviations for holes and shafts, enabling consistent specification of linear size tolerances in mechanical design and manufacturing. It is applied across engineering industries for defining fits between mating parts, such as in automotive, aerospace, and machinery production, ensuring interchangeability and quality control. The tables are used by designers, manufacturers, and quality inspectors to select appropriate tolerances and verify compliance during production and inspection processes.
