DIN 8570

The standard provides general tolerances for the linear and angular dimensions, shape, and position of welded structures. It is largely equivalent to the international standard ISO 13920 . Key Details of DIN 8570 Class B

• Fine Class: For high-precision machining.
• Medium Class (often associated with 'B'): This is generally the standard tolerance class for general mechanical engineering. It represents a balance between manufacturing cost and precision. It is tighter than a coarse grade but does not require expensive, ultra-precision tooling.
• Coarse Class: For rough machining or large structural parts.

Here is the core of what you’ll find inside the DIN 8570 B PDF. The standard defines three quality levels for weld imperfections: din 8570 b pdf
