The IEC 60073 standard covers several key aspects of electrical measuring instruments, including:
: Signals must be established early in the design phase and remain consistent across a plant or process. Means of Indication :
The standard also recognizes that for universal communication. Color-blind operators, varying lighting conditions, and different cultural contexts all necessitate supplementary coding methods. IEC 60073 therefore specifies coding by:

To assist color-blind individuals, it recommends placing Red at the top, Amber in the middle, and Green at the bottom. Developing a Compliance Report If you are developing a technical report based on a PDF version of IEC 60073 , use the following structure based on standard industrial Test Report Form (TRF) templates
Yellow or amber signals indicate an impending critical state that necessitates human monitoring or intervention:
This article explores the core principles of IEC 60073. It explains how colors, shapes, and positions create a universal language for indicator lights and actuators. What is IEC 60073? The IEC 60073 standard covers several key aspects

Are you designing for a (e.g., automotive, oil & gas, medical)?
In any industrial, medical, or consumer control environment, a human operator must interact with machinery. This interaction relies heavily on visual, auditory, and tactile cues—lights, buzzers, and buttons. Without standardization, a flashing red light could mean “emergency stop” on one machine and “normal operation” on another, leading to catastrophic errors. IEC 60073 therefore specifies coding by: To help
Indicates an immediate hazard or critical condition that requires urgent action (e.g., a dangerous malfunction, fire, or safety device tripped).
