The standard is currently in its sixth edition (), though a seventh edition is forecasted for publication in early 2027. It applies to a wide range of hardware, from simple single indicator lights and push-buttons to complex control stations and video display screens (HMIs).
Correctly selecting pilot lights, illuminated pushbuttons, and emergency stop switches.
Color is the most common form of signaling. IEC 60073 assigns specific meanings to help operators distinguish between normal and dangerous conditions: Smart Serve Answers 2014
Do you need to align this with like NFPA 79 or OSHA requirements? What types of machinery are you currently working on? Share public link
Pre-set value configuration, mandatory manual inspection prompt. Neutral / General Monitoring general state; no specific safety urgency. Power supply ON, auxiliary circuits energized. 2. Coding for Actuators (Pushbuttons) iec 60073 pdf
In industrial automation and electrical engineering, clear communication between machines and human operators is critical. A single misunderstood signal can lead to costly downtime, equipment damage, or severe workplace injuries. To standardize how machines communicate status and accept commands, the International Electrotechnical Commission established .
Understanding IEC 60073: The Global Standard for Coding Indicators and Actuators
Armed with the standard, Marco began a quiet revolution. He walked the plant at midnight, replacing ambiguous stickers with standard-compliant icons. He re-lit the alarm panel with harmonized colours; he adjusted the sequence of tones so the crew could distinguish a failing pump from a clogged valve without reading a manual. Small changes. Measured. Human.
Emergency stop buttons are universally designed as large, mushroom-shaped heads so they can be struck easily with a palm. The standard is currently in its sixth edition
Engineers need the precise definitions of color coding for HMI panels.
Having the is essential for engineers and safety officers because it allows for:
: Use of physical textures or vibrations, often for buttons or actuators to assist operators without looking. IEC Webstore Where to Access the Document
Use for safe, normal execution and starting functions. Color is the most common form of signaling
Typically used to draw attention to an abnormal but non-critical change of state.
Actuators are components that an operator manipulates to change a system state. IEC 60073 sets separate rules for pushbuttons to avoid confusion with indicator lights.
Are you designing a or a digital HMI screen ? What industry is this equipment being built for?
In Europe and many global markets, compliance with harmonized standards derived from IEC 60073 (such as EN 60073) is mandatory for machinery safety certification.
