is considered "medium" or standard workshop accuracy. Class D is the coarsest (largest tolerances). Since DIN 8570 is withdrawn, you can get

DIN 8570, specifically supplement "B" (Beilage B), is a critical German standard for assessing weld imperfections in steel and metal constructions. While the main part of DIN 8570 defines general acceptance criteria for weld shapes and dimensions, DIN 8570 Beilage B provides a detailed illustrated catalog of impermissible welding defects – i.e., defects that are not allowed regardless of the acceptance level. Class D is the coarsest (largest tolerances)

In conclusion, while technical standards like DIN 8573 may seem like dry, bureaucratic documents to the outsider, they are in fact the invisible scaffolding of modern technology. By defining the rigorous criteria for testing soldered joints, DIN 8573 ensures that the connections holding our world together—those within our cars, our computers, and our infrastructure—are robust and reliable. As materials science advances and manufacturing techniques evolve, the principles laid out in such standards remain timeless: that quality must be measured, verified, and standardized to ensure the safety and progress of society.

DIN 8570 was largely superseded by ISO 13920 (for general tolerances) and ISO 5817 / ISO 10042 (for weld imperfections). However, many legacy German blueprints and repair manuals still reference DIN 8570 B directly.

Thus, when someone searches for , they typically want the complete Part B document to inspect all three levels, or specifically the highest quality level (B) tables.
