Understanding DIN 8570 Beilage B – Welding Impermissible Defects (PDF Reference)

Here are the key editions:

When referencing this standard on your technical drawings, use clear, standardized notation in the title block. The standard callout format is usually written as: din 8570 b pdf

Welded plates often warp. Class B sets clear boundaries for how much a plate or profile can bow or twist after the welding process is complete. This is usually measured as a maximum peak-to-valley distance over a specified reference length (e.g., a maximum deviation of 2mm over a 1-meter span). Why Use DIN 8570 Class B?

For weld edge preparation, the relevant international standard is ("Welding and allied processes — Types of joint preparation"). Understanding DIN 8570 Beilage B – Welding Impermissible

Despite its withdrawal, thousands of legacy contracts, repair orders, and OEM specifications still reference “DIN 8570-B”. In industries like heavy machinery, shipbuilding, and offshore, a drawing created in 1998 may still be active. Forcibly “updating” the standard to ISO 5817 without a formal deviation could cause contractual disputes.

DIN 8570 has largely been replaced or harmonized with international standards (e.g., ISO 5817, ISO 13919). However, many older technical files, maintenance specifications, and German manufacturing guidelines still explicitly require DIN 8570 Beilage B as a reference. This is usually measured as a maximum peak-to-valley

Very Coarse (For rough structures where precision is not critical)

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.
