It is important to note that IEC 61346 was withdrawn and replaced by IEC 81346-1:2009
: It prevents confusion between different engineering disciplines (electrical, mechanical, civil) by providing a common language. Digital Integration
project, you should look for the IEC 81346 PDF series instead. Where to Find It
. The newer version expands on the "Object Interest" philosophy and is more compatible with modern BIM (Building Information Modeling) and international software standards. If you are starting a iec 61346-1 pdf
: By combining these aspects with specific letter codes, you create a "Reference Designation" (RDS) that tells you exactly what a part is and where it fits. For example, a motor might be designated by its function in a ventilation system rather than just being called "Motor #5." Hierarchical Structure
: Many existing plants and power stations still use these designations. Standardizing Design
: Modern CAD and PLM (Product Lifecycle Management) software rely on these structuring principles to automate parts lists and schematics. Transitioning to IEC 81346 It is important to note that IEC 61346
series, it remains a cornerstone for engineers, architects, and designers who need a systematic way to classify and designate components within complex projects. What is IEC 61346-1? The standard, titled
"Industrial systems, installations and equipment and industrial products — Structuring principles and reference designations — Part 1: Basic rules"
: It allows for a "tree" structure where a plant is broken down into sections, then units, then individual components, ensuring nothing gets lost in large-scale documentation. Why Do You Need the PDF? The newer version expands on the "Object Interest"
, provides the framework for identifying objects within a system. Instead of random numbering, it uses a letter-code system based on the purpose or task of an object. Key Concepts of the Standard The Aspect Concept : IEC 61346-1 introduces three ways to view a system: Function (==) : What the object does. Product (-) : What the object is (the physical hardware). Location (+) : Where the object is situated. Reference Designations
