EN ISO 13920 bridges this gap by offering a menu of tolerance classes, allowing the engineer to select the appropriate level of precision based on functional requirements. like conveyor frames or structural beams

This report summarizes the technical specifications and application of , an international standard for general tolerances in welded constructions. Overview of EN ISO 13920-BF

The standard establishes tolerance classes for four key geometric characteristics:
