Overview
ISO 3952-3:1979 is an International Organization for Standardization (ISO) standard that defines a system of graphical symbols for kinematic diagrams, specifically covering Geneva and ratchet mechanisms, and couplings, clutches and brakes. Published in 1979 as Part 3 of ISO 3952, the standard aims to simplify and harmonize the preparation and interpretation of kinematic diagrams used in technical documentation, engineering drawings and educational literature across industries and countries.
Key topics and requirements
- Establishes a standardized set of graphical symbols for elements of kinematic diagrams, improving clarity and interchangeability of technical drawings.
- Applies to symbols representing:
- Geneva mechanisms and ratchet mechanisms
- Couplings, clutches and brakes
- Intended usage:
- Diagrams in technical documentation, manuals and specifications
- Technical and educational literature (textbooks, instructional materials)
- Scope:
- Applicable across all branches of industry where machine motion and element interactions are described.
- Emphasis on international consistency to facilitate understanding by specialists of different countries.
- Part of a three-part series (ISO 3952 Parts 1–3) developed by ISO/TC 10 (Technical drawings), ensuring compatibility with broader kinematic and drawing conventions.
Practical applications
ISO 3952-3 supports clearer communication and reduced ambiguity in any context where motion and machine-element behavior must be documented or taught:
- Creating standardized kinematic diagrams for machine design and motion studies
- Engineering drawings for mechanical systems involving intermittent motion (Geneva), indexing (ratchets), and power transmission (couplings, clutches, brakes)
- Technical manuals, assembly instructions and maintenance documentation
- Patent drawings and regulatory submissions that require internationally recognized graphical conventions
- Academic and vocational teaching materials in mechanics and machine elements
Who should use this standard
- Mechanical engineers and machine designers
- Technical draftsmen and CAD specialists producing kinematic diagrams
- Technical illustrators and documentation authors
- Educators and curriculum developers in mechanical engineering and applied mechanics
- Standards committees and organizations aligning drawing conventions across borders
Related standards
- ISO 3952 Part 1 and Part 2 (other families of kinematic symbols covering motion of links, kinematic pairs, linkages, cams, friction and toothed mechanisms)
- Other ISO standards on technical drawings and drafting conventions produced by ISO/TC 10
ISO 3952-3:1979 helps ensure consistent, language-independent representation of key motion elements-making mechanical designs and instructional materials clearer, reusable, and easier to share internationally.
Frequently Asked Questions
ISO 3952-3:1979 is a standard published by the International Organization for Standardization (ISO). Its full title is "Kinematic diagrams - Graphical symbols". This standard covers: The symbols system is intended for simplifying the preparation of diagrams of products in all branches of industry and is to be used in technical documentation as well as in technical and educational literature.
