Buy the current replacement standard (ISO 13920) at Beuth Verlag .
The standard provides acceptance criteria, not a certification method. You still need trained NDT personnel (VT Level 2, RT, UT) to measure imperfections and compare them to the tables.
Covers geometrical tolerances, including shape and position . Tolerance Classes
Angular tolerances govern the variation allowed on intended angles (like a perfect 90-degree T-joint). These are determined by the length of the shorter leg of the angle being measured. din 8570 b pdf
If you are updating technical documentation, it is highly recommended to reference rather than DIN 8570 B, though the tolerance values are largely similar.

Your best strategy is twofold:
Relaxed structural bounds; ideal for massive structural frames. Very Coarse
To harmonize European and international manufacturing, the International Organization for Standardization (ISO) introduced ( "Welding — General tolerances for welded structures — Dimensions for lengths and angles — Shape and position" ). Covers geometrical tolerances, including shape and position
When a drawing specifies (often written fully as DIN EN ISO 13920 Class B, which has largely superseded it), it dictates a specific level of accuracy required for the fabrication. 1. What is DIN 8570?
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.
In modern global manufacturing, many older DIN standards have been harmonized with international standards.
