I couldn’t find a direct PDF of DIN 8570 Part B (likely referring to DIN 8570-2: Welding positions – Definitions), but here’s what’s useful to know:

  • DIN 8570-2 defines welding positions (flat, horizontal, vertical, overhead) and their notations for quality documentation.
  • It’s largely aligned with ISO 6947 and AWS standards. For example, PA = flat (ISO 6947), corresponding to 1G/1F.
  • The standard is not freely available online—you must purchase it from Beuth Verlag (DIN’s publisher) or access via institutional subscription.
  • Useful alternatives:
    • Search for “ISO 6947 welding positions” (free summaries exist).
    • Check welding handbooks or training materials that reference DIN 8570.
    • Look for “DIN 8570-2 Beuth preview” (often a few pages free).

If you need it for work or study, your company’s quality or engineering department might have a licensed copy. Would you like a summary of the welding position notations instead?


3. Check ISO 5817 – The Direct Replacement

While not identical, ISO 5817:2023 (Steel) and ISO 10042 (Aluminum) are the functional successors. Most companies have issued internal bridging documents that map old DIN 8570-B levels to new ISO quality levels (e.g., DIN 8570-B2 ≈ ISO 5817 Quality Level C). Download the ISO 5817 PDF from your national standards body instead.

⚠️ Warning: Avoid free PDF hosting sites (scribd.com, docplayer.net, etc.). Many host scanned copies of the 1993 edition, which violate copyright. More importantly, they may be incomplete or illegible.

Conclusion: Why You Still Need the DIN 8570 B PDF

Despite being superseded, DIN 8570-B remains a cornerstone of weld quality assessment in many industries, particularly in Germany and Eastern Europe. Whether you are a welding engineer, QC manager, or inspector, having a legitimate PDF copy of this standard allows you to:

  • Interpret older drawings correctly
  • Avoid costly re-inspections or rejections
  • Train personnel on historical quality limits
  • Ensure compliance with contractual obligations

Key Weld Imperfections Covered in DIN 8570-B (Table Overview)

While we cannot reproduce the entire standard here (copyright protected), any genuine DIN 8570 B PDF will include detailed tables. Below is a summary of typical categories and limits for Quality Level B (strictest):

| Imperfection | Quality Level B Limit | |--------------|------------------------| | Longitudinal crack | Not permitted | | Transverse crack | Not permitted | | Porosity (single pore) | Max. 0.3 mm diameter | | Porosity (cluster) | Max. 2% of weld area | | Undercut | Depth ≤ 0.5 mm | | Excess weld metal (reinforcement) | ≤ 1 mm + 0.1 x weld width | | Incomplete penetration | Not permitted (except by design) | | Concavity (root side) | ≤ 0.5 mm | | Linear misalignment | ≤ 0.2 x plate thickness, max. 2 mm |

For quality levels C and D, the limits are more lenient (e.g., larger porosity allowed, deeper undercut permitted).


Practical recommendation

  • For procurement or inspection, require the supplier to provide a DIN 8570 B test certificate and include specific acceptance limits (e.g., allowable vibration levels, backlash tolerance) in the contract.
  • If you need a template test report or a concise checklist tailored to your gear type (spur/helical/planetary) and expected power rating, specify gear details and I will create one.

DIN 8570 is a withdrawn German standard for general tolerances in welded structures that has been superseded by DIN EN ISO 13920.

The designation "B" typically refers to Class B, which represents "medium" or "customary workshop accuracy" for linear and angular dimensions. 🛠️ Overview of DIN 8570 Class B

This standard simplifies technical drawings by providing default permissible deviations when specific tolerances aren't listed for a weldment.

Four Accuracy Classes: A (Fine), B (Medium), C (Coarse), and D (Very Coarse).

Application: Used for linear dimensions (external, internal, offsets, center distances) and angular dimensions (including right angles).

Criteria: Selection is based on the functional requirements of the welded assembly. 📏 General Tolerances for Class B

While the full official text is copyrighted and sold by organizations like DIN Media, the typical values for Class B (medium) are as follows: Linear Dimensions (mm) Nominal Range (mm) Tolerance (± mm) Over 30 to 120 Over 120 to 400 Over 400 to 1000 Over 1000 to 2000 Angular Dimensions Length of Short Leg (mm) Tolerance (± degrees/minutes) Over 400 to 1000

📍 Key Point: If your project requires higher precision than these "B" values, you must specify individual tolerances on the drawing according to DIN 406 Part 2. 📄 Accessing the Full PDF

The keyword DIN 8570 B refers to a specific tolerance class within the German industrial standard DIN 8570, which outlines general tolerances for welded structures. While this standard was officially superseded in 1996 by the international standard ISO 13920, it remains widely cited in legacy engineering drawings and technical documentation across the globe. Understanding DIN 8570

DIN 8570 is designed to simplify engineering drawings by providing general tolerances for linear and angular dimensions, as well as form and position (straightness, flatness, and parallelism) for welded assemblies. The standard is divided into multiple parts: Part 1: Focuses on linear and angular dimensions.

Part 3: Focuses on geometrical tolerances such as shape and position. Tolerance Class B: The "Customary" Standard

The designation "B" in DIN 8570-B specifies a particular accuracy class for linear and angular dimensions. Most welded structures do not require the high precision of machined parts, so DIN 8570 defines four classes based on "customary workshop accuracy": Class A: Fine (high accuracy).

Class B: Medium (the most common standard for general engineering). Class C: Coarse. Class D: Very Coarse. Linear Dimension Tolerances for Class B

For Class B, the permissible deviations depend on the nominal length of the welded component. According to available technical tables from DIN 8570, the limit deviations in millimeters for Class B include: Up to 30 mm: ±1plus or minus 1 Over 120 to 400 mm: ±2plus or minus 2 Over 1000 to 2000 mm: ±4plus or minus 4 Over 4000 to 8000 mm: ±8plus or minus 8 Transition to ISO 13920

Since November 1996, DIN 8570 has been replaced by DIN EN ISO 13920. If you are working on a new project, it is recommended to use the ISO 13920 guidelines instead. The tolerance values in ISO 13920-B are identical to those previously found in DIN 8570-B, ensuring continuity for engineers transitioning between the two standards. Accessing the PDF

DIN 8570-B refers to a specific tolerance class within the DIN 8570 standard for general tolerances of welded structures It is important to note that DIN 8570 has been largely superseded by ISO 13920

. If you are looking for current technical specifications for new projects, you should refer to ISO 13920 Class B (linear/angular dimensions) or (straightness, flatness, and parallelism). Key Details of DIN 8570 Class B

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

: Class B is typically the second finest class (after Class A), representing a medium-high level of precision for welded components.

: It covers linear dimensions (lengths, widths, heights) and angular dimensions. : Focuses on linear and angular dimensions. : Focuses on form and position (geometrical) tolerances.

: The choice of "Class B" should be based on the functional requirements of the welded part—if it needs to fit precisely into another assembly, Class B or A is often specified. Where to Access PDF Guides
