ANSI/ASME B4.1-1967 (R2009) pdf - Preferred Limits and Fits for Cylindrical Parts 圆柱形零件的公差极限与配合
This standard defines terms applicable to fits between plain (non-threaded) cylindrical parts and recommends preferred sizes, allowances, tolerances, and fits for use wherever they are applicable. The standard covers a diameter range of up to 20 inches, in line with the recommendations of the American-British-Canadian Conferences. Experimental work is underway, and when results become available, agreement will be sought on the range above 20 inches.
