How SN EN ISO 1101:2017 approaches the topic
SN EN ISO 1101:2017 provides a comprehensive framework for geometrical tolerancing, encapsulating the latest advancements in GPS. This standard outlines guidelines for various tolerances of form, orientation, location, and run-out, which are essential for ensuring the functionality and interchangeability of components. The document emphasizes the importance of clarity in technical drawings, incorporating universally recognized symbols that aid in the interpretation of geometrical specifications. Notably, SN EN ISO 1101:2017 enhances the treatment of complex geometries and movable assemblies, offering supplementary information to facilitate better understanding and application in 3D CAD models. This approach aligns with the increasing demands for precision in modern manufacturing processes.
How ISO 1101:2017 vs 2012 approaches the topic
ISO 1101:2017 builds upon the foundational elements established in ISO 1101:2012, refining the specifications regarding geometrical tolerances. The 2017 update introduces more precise definitions and improved clarity in the presentation of tolerances. It enhances the specification of tolerance zones and the indicators for planes and geometry elements, thereby providing a more robust framework for engineers and designers. Key updates also include the introduction of defaults in drawing specifications, which streamline the design process by reducing ambiguity. Overall, ISO 1101:2017 reflects the evolving practices in the industry, ensuring that the standards remain relevant and effective in facilitating high-quality manufacturing.
Side-by-side comparison
| Criteria | SN EN ISO 1101:2017 | ISO 1101:2012 |
|---|---|---|
| Scope | Comprehensive guidelines for geometrical tolerancing in GPS | Foundational guidelines for geometrical tolerancing |
| Audience | Engineers, quality managers, and regulatory professionals | Engineers and designers in manufacturing |
| Cost/Effort | May require additional training due to complexity of updates | Familiarity with previous standards suffices |
| Certification Mechanism | Adherence to guidelines assessed through audits | Previous certification mechanisms apply |
| Typical Use Cases | Advanced manufacturing, complex geometries, 3D CAD modeling | Standard manufacturing, basic geometrical tolerancing |
When to choose which
- If you are developing complex geometries that require advanced tolerancing techniques, choose SN EN ISO 1101:2017 for its comprehensive guidelines.
- If your organization is already familiar with ISO 1101:2012, and your tolerancing needs are basic, you may continue using ISO 1101:2012 to maintain consistency in your processes.
- If you are implementing 3D CAD models and need the latest specifications for clarity and precision, opt for SN EN ISO 1101:2017.
- If cost and training resources are limited, the familiarity and established framework of ISO 1101:2012 may be more suitable until you can transition to the latest standards.
SN EN ISO 1101:2017
Geometrische Produktspezifikation (GPS) - Geometrische Tolerierung - Tolerierung von Form, Richtung, Ort und Lauf (ISO 1101:2017)
Geometrical product specifications (GPS) - Geometrical tolerancing - Tolerances of form, orientation, location and run-out (ISO 1101:2017)
ISO 1101:2017 defines the symbol language for geometrical specification of workpieces and the rules for its interpretation. It provides the foundation for geometrical specification. The illustrations in this document are intended to illustrate how a specification can be fully indicated with visible annotation (including e.g. TEDs). NOTE 1 Other International Standards referenced in Clause 2 and in Tables 3 and 4 provide more detailed information on geometrical tolerancing. NOTE 2 This document gives rules for explicit and direct indications of geometrical specifications. Alternatively, the same specifications can be indicated indirectly in accordance with ISO 16792 by attaching them to a 3D CAD model. In this case, it is possible that some elements of the specification are available through a query function or other interrogation of information on the model instead of being indicated using visible annotation
