This standard is widely used in machine construction , steel structures , rail vehicles, and shipbuilding. Tolerance Tables Overview
Therefore, a callout of indicates that a workshop must meet medium precision constraints across all dimensional, angular, and geometric orientations. Linear Dimension Tolerances (Class B)
If your project calls for Class tolerances (whether BD or BC), you are working within the most common parameters for general fabrication.

For linear measurements, Class B dictates the following permissible deviations: ±1 mm Over 30 mm to 120 mm: ±1 mm Over 120 mm to 400 mm: ±2 mm Over 400 mm to 1000 mm: ±3 mm Over 1000 mm to 2000 mm: ±4 mm Over 2000 mm to 4000 mm: ±6 mm Over 4000 mm to 8000 mm: ±8 mm Over 8000 mm to 12000 mm: ±10 mm Over 12000 mm to 16000 mm: ±12 mm Over 16000 mm to 20000 mm: ±14 mm Over 20000 mm: ±16 mm Angular Dimensions
