Therefore, a request for a guideline means the manufacturer must adhere to the Medium tolerance class across the fabrication's dimensions and geometry. Key Dimensions Covered Under Tolerance Class B

When a drawing says “DIN 8570-B2”, it means: All weld imperfections must conform to the medium quality level as per part B of the standard.

By applying these general tolerances, manufacturers can avoid detailing individual tolerances for every single dimension on a technical drawing. This simplifies design work and streamlines shop-floor production. The Role of Part B (DIN 8570-B)

The standard is a historical German standard that specifies general tolerances for welded structures. While it was officially superseded by DIN EN ISO 13920 in 1996, it is still frequently referenced in legacy engineering documents and drawings. Overview of DIN 8570 Therefore, a request for a guideline means the

Welding often causes long beams or plates to bow or twist. This category defines the maximum gap allowed between the surface of the welded component and a straightedge or reference plane.

For steel welds, the numerical limits are almost identical. However, ISO 5817 introduces new imperfection types (e.g., root concavity, mismatch) that DIN 8570-B did not explicitly cover. Therefore, directly substituting the standard without a technical review is not advisable.
