Because color blindness affects a portion of the population, IEC 60073 emphasizes that color should not be the sole means of conveying critical safety information. Supplementary coding includes:

Note: For (buttons), Green is strictly forbidden for STOP/OFF functions, while Red is strictly forbidden for START/ON functions. Beyond Just Color: Flash and Shape

In industrial automation and electrical engineering, clarity saves lives. The international standard establishes a unified framework for the colors and alternative codings used on indicator lights, pushbuttons, and other human-machine interface (HMI) components.

While a simple green light means "safe," complex SCADA (Supervisory Control and Data Acquisition) screens often require more nuance. The PDF outlines how to handle conflicting signals and prioritize multiple alarms simultaneously. Cross-Standard Compatibility iec 60073 pdf

When looking for the PDF, you may see an option for a "" version. This premium document contains the full text of the standard with all changes, additions, and deletions from the previous version clearly marked. It is extremely useful for engineers who need to quickly understand what has changed in a new edition.

Color is the most critical element of visual coding. IEC 60073 assigns specific, non-negotiable meanings to colors used on indicator lights and actuators (push-buttons). Meaning for Indicator Lights Meaning for Actuators (Buttons) Danger / Emergency Act to respond to danger (Stop) Emergency stop, fire alarm Yellow Abnormal / Warning Act to suppress abnormality Overload warning, reset Green Safe / Normal Act to initiate safe conditions Start machine, normal flow Blue Mandatory action Act requiring mandatory intervention Fill fluid, check gauge White/Gray Neutral / No specific meaning General initiate/stop functions General power on, cycle start 2.

👉 Latest edition 2002 (Confirmed) 👉 Pro tip: Don't confuse flashing rates (slow vs. fast) – the PDF defines exactly when to use each. Because color blindness affects a portion of the

IEC 60073 is an international standard published by the International Electrotechnical Commission (IEC). The standard focuses on functional safety and the safety of the overall system, providing guidelines for ensuring the safety of electrical, electronic, and programmable electronic control systems.

is the international standard that governs the coding principles for indicators and actuators. It establishes a universal visual and tactile language for machine interfaces, ensuring that operators worldwide can understand equipment states instantly and react safely during emergencies. This comprehensive guide explores the core principles of IEC 60073, its color and behavior assignments, and how to utilize the official PDF document for engineering and compliance.
