ISO 14617 is a multi-part international standard titled "Graphical symbols for diagrams" . It establishes a harmonized library of symbols used to create and interpret technical diagrams. These diagrams are critical for designing, manufacturing, and maintaining complex engineering systems. The standard is divided into several parts, including: : General information and indexes.

Symbols with general applications (basic shapes and supplementary symbols). Part 3: Connections and related devices. Part 4: Actuators and related devices. Part 5 & 6: Measurement and control devices/functions.

: General information, rules for presentation, and comprehensive indexes.
Because the symbols themselves are not copyrightable (only the specific layout and explanatory text of the standard are), many engineering blogs, software companies, and training centers have created derivative
| Part | Title | Focus & Content | | :--- | :--- | :--- | | | General information and indexes | Serves as an introduction, providing general rules for creating and applying symbols, instructions on using registration numbers, and a comprehensive index to all symbols in the series. | | Part 2 | Symbols having general application | Contains a library of basic and supplementary symbols used to build more complex symbols, covering a wide range of industrial needs. | | Part 3 | Connections and related devices | Specifies symbols for various types of connections used in diagrams, such as pipelines, electrical lines, and mechanical linkages. | | Part 4 | Actuators and related devices | Provides symbols for components that create motion or perform actions, including cylinders, motors, and other actuating elements. | | Part 5 | Measurement and control devices | Focuses on instruments and devices used for measuring and controlling variables like pressure, temperature, flow, and level. | | Part 6 | Measurement and control functions | Specifies symbols for the functions themselves (e.g., sensing, transmitting, indicating) which can be applied to generic blocks in control diagrams. | | Part 7 | Basic mechanical components | Covers symbols for fundamental mechanical parts like shafts, couplings, bearings, and spring elements. | | Part 8 | Valves and dampers | A critical collection of symbols for all types of valves used to control the flow of fluids, including gate, globe, ball, and check valves. | | Part 9 | Pumps, compressors and fans | Specifies symbols for devices that move liquids, gases, or air, such as centrifugal pumps, reciprocating compressors, and axial fans. | | Part 10 | Fluid power converters | Contains symbols for components that convert fluid power (hydraulic or pneumatic) into mechanical motion or vice versa, like pumps and motors specifically for fluid power systems. | | Part 11 | Devices for heat transfer and heat engines | Provides symbols for equipment like heat exchangers, boilers, furnaces, and internal combustion engines. | | Part 12 | Devices for separating, purification and mixing | Focuses on process equipment such as filters, centrifuges, separators, and mixers. | | Part 13 | Devices for material processing | Includes symbols for machinery used in industrial processing, like crushers, mills, and extruders. | | Part 14 | Devices for transport and handling of material | Covers material handling components like conveyors, elevators, hoppers, and feeders. | | Part 15 | Installation diagrams and network maps | Specifies symbols for use on installation diagrams (e.g., for buildings) and network maps, often for plumbing, HVAC, or IT infrastructure. | ISO 14617 is a multi-part international standard titled

University professors and students need to learn the symbols. They rarely need the very latest "official" PDF for a semester project; they need a functional copy of the graphical tables.
Covers heat exchangers, boilers, and cooling towers. The standard is divided into several parts, including:
The standard is broken down into 15 parts (ISO 14617-1 to ISO 14617-15), each covering a specific domain:
You can preview parts of the standard, including the introduction, scope, and some terms, directly on the ISO OBP website Sample Previews:
Imagine a piping engineer from Germany handing a P&ID (Piping and Instrumentation Diagram) to a maintenance team in Brazil. Without ISO 14617, a gate valve could look like a globe valve, and a centrifugal pump might be mistaken for a positive displacement pump.
It is crucial to understand that ISO standards are protected by copyright. You cannot legally host a complete ISO 14617 PDF for public download. The organizations that have uploaded such documents to file-sharing sites have, in almost every case, infringed on ISO's copyright and the rights of the British Standards Institution (BSI) or other national bodies that adopt the standards. For example, a quick inspection of an uploaded BS ISO 14617-7:2002.pdf file reveals a BSI copyright notice, a clear statement that it is a "Licensed Copy," and a notice that it is an "Uncontrolled Copy". These watermarks and notices are not just formalities; they are legal declarations that the document was obtained and is being redistributed without permission.
