Comparison of ISO 13920:2023 and SN EN ISO 13920:1997
The following content provides a detailed comparison of SN EN ISO 13920:2023 against ISO 13920:2023 and SN EN ISO 13920:1997. This analysis aims to guide professionals in determining which standard is best suited for their specific needs in welded constructions.
SN EN ISO 13920:2023
Schweissen - Allgemeintoleranzen für Schweisskonstruktionen - Längen‑ und Winkelmasse, Form und Lage (ISO 13920:2023)
Welding - General tolerances for welded constructions - Dimensions for lengths and angles - Shape and position (ISO 13920:2023)
This document specifies general tolerances for linear and angular dimensions and for shape and position of welded structures in four tolerance classes, based on customary workshop accuracy. The main criterion for selection of a particular tolerance class is based on the functional requirements which are to be met. The applicable tolerances are always those which are stated in the drawing. Instead of specifying individual tolerances the tolerance classes according to this document can be used. General tolerances for linear and angular dimensions and for shape and position as specified in this document apply for weldments, welding assemblies, welded structures, etc. Special provisions can be necessary for complex structures. The specifications given in this document are based on the independency principle of ISO 8015, according to which the dimensional and geometrical tolerances apply independently of each other. Manufacturing documentation in which linear and angular dimensions or indications for shape and position are presented without individually indicated tolerances shall be deemed incomplete if there is no, or inadequate, reference to general tolerances. This does not apply to temporary dimensions.

Why compare SN EN ISO 13920:2023 and comparison of ISO 13920:2023 and SN EN ISO 13920:1997
This comparison is particularly relevant for engineers, quality control professionals, and manufacturers who are involved in the design and production of welded structures. As the industry evolves and new standards emerge, understanding the differences between these two documents can influence compliance, production quality, and overall project success. Decision-makers often seek clarity on which standard aligns better with their operational requirements, project specifications, and regulatory obligations. By investigating the nuances between SN EN ISO 13920:2023 and its predecessor, SN EN ISO 13920:1997, stakeholders can better navigate the complexities of tolerance requirements in welded constructions.
=== SECTION 2 ===
How SN EN ISO 13920:2023 approaches the topic
SN EN ISO 13920:2023 establishes comprehensive general tolerances for lengths, angles, shapes, and positions in welded constructions, categorized into four distinct tolerance classes based on workshop accuracies. This updated standard emphasizes the independence principle in tolerances, which states that tolerances for different dimensions can be applied independently, thereby enhancing flexibility in manufacturing processes. The document also outlines specific requirements for manufacturing documentation, ensuring that all stakeholders have a clear understanding of the tolerances to be adhered to. This approach enables manufacturers to produce complex components with greater precision and compliance to modern standards, reflecting the latest advancements in technology and best practices in welding.

How comparison of ISO 13920:2023 and SN EN ISO 13920:1997 approaches the topic
In contrast, SN EN ISO 13920:1997 laid the foundational framework for general tolerances in welded constructions but lacked some of the precision and clarity offered by its successor, SN EN ISO 13920:2023. The previous standard did not fully address the independence principle, which has now been incorporated to allow for a more flexible approach to tolerance application. Additionally, the 1997 version had different tolerance classes that may not align with contemporary manufacturing practices. The evolution from the 1997 document to the current 2023 version reflects significant advancements in welding technology and manufacturing processes, addressing the growing complexity of welded structures in various industries.

When to choose which
- If you are working on complex welded structures that require high precision and updated tolerances, choose SN EN ISO 13920:2023.
- If you are involved in projects that adhere to older specifications or simpler constructions, SN EN ISO 13920:1997 may suffice.
- For organizations looking to future-proof their manufacturing processes and ensure compliance with modern standards, opt for ISO 13920:2023 compliance standards.
- If your team is well-versed in the older standards and you are not ready for a transition, consider maintaining SN EN ISO 13920:1997 until full integration of the newer standards can be achieved.
