Here’s a draft text you can use for a website, forum post, or document that references DIN 8570 Beilage B (often shortened to “DIN 8570 B PDF”).
If you let me know the exact context (e.g., “I need this for work instructions,” “for a welding engineer exam,” or “to request a download”), I can adjust the tone.
The DIN 8570 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 While it was officially superseded by DIN EN ISO 13920 in 1996, it is still frequently referenced in legacy engineering documents and drawings.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 din 8570 b pdf

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.

It is important not to confuse the "B" in DIN 8570-B with quality level "B". The standard itself is Part B, but it contains three quality grades: DIN 8570-A: General guidance and terminology
Application: Tolerances in Class B increase as the size of the nominal dimension increases. For example, a longer beam will have a larger permissible variation than a shorter one under the same class. Parts of the Standard DIN 8570-1: Covers linear and angular dimensions.
Key imperfections limited by quality level B:
