| Nominal Size (mm) | Permitted Flatness Deviation (Class B) | | :--- | :--- | | Up to 120 | 1 mm | | 120 to 400 | 1.5 mm | | 400 to 1,000 | 2 mm | | 1,000 to 2,000 | 2.5 mm | | 2,000 to 4,000 | 3 mm | | 4,000 to 8,000 | 4 mm | | > 8,000 | 5 mm |
For linear dimensions (length, width, spacing), the deviations are roughly for small dimensions, scaling up based on the nominal size.
The ISO 13920 standard specifies general tolerances for linear and angular dimensions, as well as for shape and position of welded structures. It is designed to ensure functional suitability in manufacturing without requiring excessive precision that could increase costs unnecessarily. Breaking Down "BF"
: Often paired with ISO 2768-mK (which covers tolerances for machined parts) to provide a complete specification for assemblies that include both welded and machined features.
