Introduction: What is DIN 8570 B?

If you work in welding engineering, fabrication, or quality control, you’ve likely encountered the term DIN 8570. This German standard (also adopted in various forms across European manufacturing) is the go-to reference for shape deviations and weld imperfections on welded metal structures.

But the search term “DIN 8570 B PDF” points to a very specific part of this standard: Form B (often referred to as Form B – Quality levels for imperfections).

In this long-form post, we’ll cover:

Important note: DIN 8570 was largely superseded by ISO 13920 (for general tolerances) and ISO 5817 / ISO 10042 (for weld imperfections). However, many legacy German blueprints and repair manuals still reference DIN 8570 B directly.

Conclusion

Searching for a “DIN 8570 B PDF” is a common reflex for welders and engineers facing a legacy German drawing. While the original document is no longer active, its quality level B remains the gold standard for critical weld integrity.

is a classic German standard that specifies general tolerances for welded structures. Specifically, Tolerance Class B (often written as DIN 8570-B

) represents a "medium" level of accuracy commonly achieved in standard industrial welding workshops. It is important to note that DIN 8570 has been largely superseded by DIN EN ISO 13920

. However, it is still frequently referenced in older technical drawings and maintenance manuals. Intertek Inform Key Aspects of DIN 8570 Class B

The standard is designed to simplify technical drawings by providing a default set of tolerances for linear and angular dimensions, as well as shape and position, without needing to label every single weldment. Tolerance Classes: The standard defines four classes: (Coarse), and (Very Coarse). Class B Application:

Used when "customary workshop accuracy" is sufficient. It balances precision with manufacturing cost. Dimensions Covered: Linear Dimensions: External, internal, offset, and center line distances. Angular Dimensions:

Angles indicated on drawings and those generally not indicated (like right angles). Geometric Tolerances: Straightness, flatness, and parallelism. Tolerance Values for Class B (Linear Dimensions)

The permissible deviation increases as the nominal length of the part increases. For example, in typical tables for Class B: Up to 30 mm: Over 1000 to 2000 mm: Over 4000 to 8000 mm: Modern Equivalent: ISO 13920 If you are working on a new design, you should use

The DIN 8570 standard establishes general tolerances for linear and angular dimensions, as well as the shape and position of welded structures. It is intended to simplify engineering drawings by providing a set of default "workshop accuracy" levels, reducing the need for detailed individual tolerance specifications unless higher precision is required. Tolerance Class B Overview

Within the DIN 8570 framework, Class B (often designated as DIN 8570-B) represents a specific level of permissible deviation for welded assemblies.

Accuracy Level: Class B is one of four standard classes (A, B, C, and D), where Class A is the most precise and Class D is the coarsest.

Application: It defines allowable variations based on the range of measurements; generally, the permissible tolerance increases as the size of the welded structure increases.

Drawing Designation: When this standard is applied, the designation (e.g., "DIN 8570-B") must be entered in the appropriate area on the technical drawing to ensure manufacturing compliance. Key Technical Aspects din 8570 b pdf

Linear and Angular Measurements: The standard establishes specific millimetric and degree-based limits for deviations in straightness, parallelism, and positioning.

Combinations: Class B for linear dimensions can be combined with other classes for geometrical tolerances, such as those found in DIN 8570 Part 3 (e.g., a designation like DIN 8570-BE).

Testing: Verification of these tolerances requires the use of testing and measuring devices that comply with relevant DIN standards. Relation to Modern Standards

While DIN 8570 has been a staple in European engineering for decades, it is often referenced alongside or replaced by international standards such as ISO 13920, which also covers general tolerances for welded structures.

For those looking for official copies or specific measurement tables, documents are often available through technical repositories like the DIN 8570-1987 PDF on Scribd.

DIN 8570 was a historical German standard for general tolerances in welded structures, which has since been superseded by the international standard ISO 13920. It established standardized accuracy levels for linear and angular dimensions, as well as shape and position, to simplify technical drawings. The Role of Tolerance Class B

In DIN 8570, "B" refers to one of four specific tolerance classes for linear and angular dimensions.

Precision Levels: Class A (fine), Class B (medium), Class C (coarse), and Class D (very coarse).

Application: Class B is typically used for standard workshop accuracy where functional requirements do not demand high precision but still require controlled assembly quality.

Measurement Ranges: For class B, the permissible deviation increases with the size of the component (e.g., ±2 mm for 120–400 mm, and up to ±16 mm for lengths up to 20,000 mm). Key Components of the Standard

The standard was originally divided into parts to cover different aspects of weldment geometry:

Part 1 (DIN 8570-1): Focused on linear and angular dimensions, such as external sizes, center line distances, and right angles.

Part 3 (DIN 8570-3): Covered geometrical tolerances, including straightness, flatness, and parallelism.

Simplified Notations: Drawings would often use combined codes like "DIN 8570-BF" to indicate Class B for dimensions and Class F for geometry. Modern Equivalent: ISO 13920

Since 1996, DIN 8570 has been withdrawn and replaced by ISO 13920. Most engineering firms now use this international standard to ensure global compatibility.

DIN 8570-B refers to a specific tolerance class within the DIN 8570 standard (General tolerances for welded structures). This standard simplifies technical drawings by providing universal permissible variations for linear and angular dimensions, as well as shape and position, based on customary workshop accuracy.

Class B specifically represents one of four primary tolerance grades (A, B, C, and D) used for linear and angular measurements. While it is a moderately accurate class, it has largely been superseded by the international standard ISO 13920. Understanding DIN 8570 Tolerance Classes

The standard is divided into sections to cover different types of measurements. The designation DIN 8570-B indicates that the general tolerances for linear and angular dimensions follow class B.

Linear Dimensions: 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.

Angular Dimensions: Tolerances for angles are determined by the length of the shorter leg of the angle. Class B typically allows for deviations such as ±45' for shorter legs or ±20' for longer reference legs (over 1000mm). Transition to ISO 13920

If you are searching for a DIN 8570 B PDF, it is critical to note that this German national standard was officially withdrawn and replaced by ISO 13920:1996. Most modern engineering projects now cite the international version.

The choice of tolerance class B is usually a balance between functional requirements and manufacturing economy.

Workshop Accuracy: It reflects standard manual or semi-automated welding capabilities without requiring high-precision specialized tooling. Here’s a draft text you can use for

Indication on Drawings: To apply this class, a designer would enter "DIN 8570-B" (or the ISO equivalent) in the drawing's title block, removing the need to dimension every single weld individually.

Combinations: If a structure requires specific precision for shape (like flatness) but standard precision for length, a combined designation like DIN 8570-BE might be used. Accessing the Standard

The DIN 8570 standard provides general tolerances for the linear and angular dimensions, shape, and position of welded structures. It is largely equivalent to the international standard ISO 13920. Key Details of DIN 8570 Class B

Purpose: It simplifies engineering drawings by providing default "customary workshop accuracy" tolerances for weldments, eliminating the need to specify every individual dimension's tolerance.

Tolerance Classes: The standard defines four classes—A, B, C, and D. Class A is the finest (smallest tolerances).

Class B is considered "medium" or standard workshop accuracy. Class D is the coarsest (largest tolerances).

Application: Tolerances in Class B increase as the size of the nominal dimension increases. For example, a longer beam will have a larger permissible variation than a shorter one under the same class. Parts of the Standard DIN 8570-1: Covers linear and angular dimensions.

DIN 8570-2: Covers shape and position (geometrical tolerances). PDF Resources

Why Engineers Still Need It

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.

Thus, the search for a historic PDF remains legitimate for:

Step 1 – Obtain the Historical PDF

Acquire a licensed archival copy of DIN 8570:1993-12 (the last harmonized version). Ensure it includes both the text and the original tables.

Practical Application: Using DIN 8570-B in a QA Plan

Suppose your project specification strictly says: “All fillet welds to DIN 8570-B2, inspection by VT per DIN EN 13018.” You cannot simply say “we use ISO 5817 instead” without customer approval. Follow this workflow:

Introduction: Why DIN 8570-B Matters in Modern Fabrication

In the world of welding engineering and quality assurance, standards are the invisible backbone of safety and reliability. Among the myriad of norms governing weld quality, DIN 8570 remains a cornerstone, particularly for workshops and manufacturers operating under German or EU contractual frameworks.

If you have searched for the term “DIN 8570 b PDF” , you are likely facing a specific challenge: You need to classify, assess, or accept weld imperfections on a fabricated component, and the contractual drawing calls out “DIN 8570-B” as the acceptance criteria.

But here’s the catch: DIN 8570 is an old, withdrawn standard. It has been largely replaced by ISO 5817 and ISO 10042. So why are people still hunting for the original document? And where can you legally get a reliable PDF? This article answers both questions while giving you a technical deep dive into the “B” series of the standard.
