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

Used for general execution commands that do not carry safety implications (e.g., cycling through menu options, indexing a conveyor belt). Beyond Color: Alternative Coding Methods iec 60073 pdf

The International Electrotechnical Commission (IEC) establishes global benchmarks for electrical and electronic technologies. Among its vital publications is IEC 60073, a standard that dictates how human-machine interfaces (HMIs) communicate safety and operational status through visual, acoustic, and tactile signals.

: Standardized layouts mean faster emergency stops. Actuators initiate actions

IEC 60073 establishes general rules for assigning specific meanings to colors, alphanumeric characters, symbols, and physical positions of indicators and actuators (buttons, switches, lamps). Its primary goal is to ensure safety, reduce human error, and facilitate quick recognition of operational states. IEC 60073 assigns specific meanings to help operators

Final note for engineers: Always pair IEC 60073 with a risk assessment (ISO 12100). The standard tells you how to code; the risk assessment tells you what to code.

Tactile coding ensures that operators can identify controls by feel, which is crucial in low-light environments or during high-stress emergency situations.
