Many searches for this topic are attempts to find a free download of the standard. However, it is important to understand the legal and procedural aspects of accessing these documents:
: Medium tolerances (often used as a standard workshop baseline). : Large tolerances. : Largest tolerances (lowest precision). Application Scope
Tolerances for angles depend on the length of the shorter leg ( ) of the angle. ±plus or minus 45' (minutes) 400 to 1,000 mm: ±plus or minus 30' (minutes) Over 1,000 mm: ±plus or minus 20' (minutes) 🛠️ Why Use This Standard?
Consequently, you cannot buy an “official” DIN 8570 PDF from Beuth Verlag (DIN’s publisher) anymore. Any PDF circulating from the 1990s is and legally non-binding for new contracts unless explicitly agreed upon. din 8570 b pdf
The transition occurred to harmonize German standards with global practices. The equivalent international breakdown is typically found in (Tolerances for linear and angular dimensions). Under the ISO system:
The "B" in "DIN 8570 B" typically refers to one of the four tolerance classes (A, B, C, and D) defined in the standard. Class B (Medium Accuracy)
DIN 8570 is a standard issued by the Deutsches Institut für Normung (German Institute for Standardization). It specifies general tolerances for welded structures, focusing heavily on linear and angular dimensions, as well as shape and position (straightness, flatness, and parallelism). Many searches for this topic are attempts to
If you need the document for reference, you can use a historical version from a document-sharing site. However, for any professional or legal application, it is critical to purchase the official from DIN Media. Using the most current standard ensures your work complies with the latest industry and regulatory requirements.

If budget is an issue, request that your company purchases a multi-user license. : Largest tolerances (lowest precision)
Choosing the correct class is a balance between functional necessity and production cost.
Implementing DIN 8570-B yields several distinct advantages for fabrication shops:
While DIN 8570 B is a standard that defines general tolerances for medium-precision mechanical parts, modern engineering practices have largely shifted toward its international successor, ISO 2768. For those seeking the document, purchasing the official ISO 2768-1 standard is the best way to ensure you are working with current, legally compliant technical data.
: Class B is typically the second finest class (after Class A), representing a medium-high level of precision for welded components.
