Imagine you are building a support frame for a conveyor system.

Using this standard shorthand simplifies communication between designers and fabrication shops. Instead of calculating individual limits for every length and angle, a single note——applies a pre-defined set of rules based on the size of the component. en iso 13920-bf

ensures that their 13-ton trailers are built to a consistent quality. It prevents expensive "re-work" and ensures that if a part is made in one factory, it will perfectly match a part made in another. exact measurement tables for the "B" and "F" classes to use on a technical drawing? Imagine you are building a support frame for

Imagine a team of engineers designing a massive steel frame. They know that when you apply intense heat to metal during welding, it expands, contracts, and twists. Without a shared "tolerance" agreement, the person welding the frame might think a 5mm warp is fine, while the person installing the machinery on top thinks it's a disaster. This is where EN ISO 13920 steps in. It provides a common language for general tolerances for welded constructions Breaking Down the "BF" The suffix ensures that their 13-ton trailers are built to

Adopting these general tolerances simplifies the design and manufacturing process by:

simplifies technical drawings by removing the need for hundreds of individual plus or minus
