If all imperfections are within limits → weld accepted. If any exceed limits → repair (grind, re-weld, etc.) and re-inspect.
If budget is an issue, request that your company purchases a multi-user license.
Create a one-page table that compares each relevant imperfection in DIN 8570-B2 to the nearest equivalent in ISO 5817 Level C. State any gaps (e.g., slag inclusion limits). Use this for internal training.
To help find the exact data sheets or specific equivalents you need, tell me: Do you need to know how it compares to ?
is a highly widely referenced technical designation within the manufacturing sector, establishing standard limit deviations for linear and angular dimensions of welded steel structures. Originally published by the German Institute for Standardization ( Deutsches Institut für Normung ), this historical manufacturing benchmark significantly simplifies engineering design blueprints by providing reliable, baseline workshop accuracies. din 8570 b pdf

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.
Furthermore, the standard addresses the diverse nature of soldering materials. Soldering involves a vast array of base materials and filler metals, each with unique properties. A "one size fits all" approach to testing is insufficient. DIN 8573 accommodates this diversity by outlining tests tailored to different material combinations and joint geometries. Whether the application involves soft soldering for delicate electronics or hard soldering (brazing) for robust mechanical structures, the standard offers guidelines to detect flaws such as porosity, incomplete fusion, or brittle intermetallic phases. By identifying these microscopic defects before a product reaches the market, the standard acts as a filter, preventing catastrophic failures in the field.
For a legitimate and up-to-date PDF, the best source is (formerly Beuth Verlag). Search for "DIN 8570-1:1987-10" on their website. A 4-page PDF is available for €36.70 including VAT. For the current standard DIN EN ISO 13920:2023 , search on the DIN Media website; the PDF cost is €141.50 including VAT. If all imperfections are within limits → weld accepted
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:

Customary workshop accuracy; default selection for general engineering.

The tolerance classes mapped directly from the old German standard to the new global standard: DIN 8570 Class A →right arrow DIN 8570 Class B →right arrow ISO 13920 Class B DIN 8570 Class C →right arrow ISO 13920 Class C DIN 8570 Class D →right arrow ISO 13920 Class D
: Verified via high-resolution vernier calipers (DIN 862), standard industrial graduated steel straightedges (DIN 18701), or tensioned steel tape measures (DIN 6403).
Class B provides specific +/- deviations in millimeters based on the nominal size of the structure. For example, for measurements up to 30mm, the tolerance is ±1mm; for ranges between 400mm and 1000mm, it increases to ±3mm.
