When writing a reference designation under IEC 61346-1, you move from the highest level of the hierarchy down to the lowest, separating levels with the appropriate aspect prefix. This ensures that even if a factory has 500 identical motors, each motor has a completely unique designation because its higher-level functional or location paths are different.

Transitioning your engineering workflow to a structured system like IEC 61346-1 (or IEC 81346) offers major operational advantages: iec 61346-1 pdf
This aspect focuses on what the object is designed to do, completely independent of its physical form or location. A cooling system function. Identifier: Marked with an equal sign ( = ). 2. The Location-Oriented Aspect (Prefix: + ) When writing a reference designation under IEC 61346-1,
For instance, the series now includes , showing how the framework is being adapted to the specific needs of different industries. Whether you are an engineer, a technical writer, or a project manager, adopting the latest version of the standard ensures that your documentation practices are aligned with current international best practices.

A complete reference designation consists of a prefix indicating the aspect, followed by a combination of letters and numbers representing the class and specific item. For example, a designation might look like this: =A1-K2 = indicates a function-oriented aspect.
Investing in the authorized version ensures your engineering team designs systems that comply with international corporate bidding requirements and legal engineering frameworks.
An represents a particular viewpoint of an object. The standard identifies three main aspects:
