Iso 13920-bf High Quality — En
is the European adoption of the international standard ISO 13920:1996 – Welding – General tolerances for welded constructions . It specifies general tolerances for linear and angular dimensions, flatness, straightness, and parallelism for welded structures, where no individual tolerances are indicated on the drawing .
In the world of engineering and manufacturing, precision and accuracy are crucial for ensuring the quality and reliability of products. One of the key aspects of achieving this precision is by adhering to specific standards and guidelines that dictate the acceptable limits of variation in the dimensions and tolerances of various components and constructions. One such standard that plays a significant role in the fabrication and inspection of welded constructions and parts is EN ISO 13920-BF. en iso 13920-bf
In many industrial contexts, particularly in heavy machinery and automotive supply chains, engineers often confuse or conflate standards. The most common standard classes are: is the European adoption of the international standard

If your project calls for Class tolerances (whether BD or BC), you are working within the most common parameters for general fabrication.
