DIN 8570
The standard establishes general tolerances for linear and angular dimensions, as well as the shape and position of welded structures. It is intended to simplify engineering drawings by providing a set of default "workshop accuracy" levels, reducing the need for detailed individual tolerance specifications unless higher precision is required.

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. din 8570 b pdf
