: The standard applies to external and internal dimensions, center line distances, and angular dimensions (including right angles). Key Sections of the Standard

If you are looking for specific dimension tables or tolerance values for a particular size, let me know, and I can provide those.

Unlike precision machining tolerances (such as DIN ISO 2768 for subtractive manufacturing), welding standards must accommodate thermal expansion and localized contraction. Heating and cooling cycles distort metals, making rigid millimeter-precise machining standards impossible or highly uneconomical to apply directly to raw weldments. DIN 8570-1987 General Tolerances For Welded Structures PDF din 8570 b pdf

The standard is a historical German standard that specifies general tolerances for welded structures. While it was officially superseded by DIN EN ISO 13920 in 1996, it is still frequently referenced in legacy engineering documents and drawings. Overview of DIN 8570

To purchase the active equivalent, ISO 13920.

The standard is divided into parts that address different types of tolerances: DIN 8570-1 : Focuses on linear and angular dimensions DIN 8570-2/3 : Focuses on geometrical tolerances , including straightness, flatness, and parallelism.

The primary objective of DIN 8573 is to standardize the methods used to evaluate the mechanical and technological properties of soldered joints. In an industrial landscape where thermal and electrical conductivity is paramount, the integrity of a soldered bond cannot be left to visual inspection alone. The standard defines rigorous testing procedures that simulate the stresses a component might face during its lifecycle. By categorizing testing methods—ranging from tensile and shear tests to metallographic examinations—DIN 8573 provides engineers with a universal language for quality. Without such a standard, the assessment of solder quality would be subjective, leading to inconsistencies that could compromise the safety of complex systems.

The standard breaks down tolerances into four primary accuracy classes, ranging from high precision to rough structural fabrication:

The standard is designed to simplify engineering drawings by providing default tolerance values based on "customary workshop accuracy". Classification
