The is a foundational document for designing safe and effective man-machine interfaces. By adhering to its coding principles for indicators and actuators, engineers can create intuitive systems that enhance operator safety and operational efficiency. Always rely on the latest PDF version to ensure your designs meet current global standards.

Used for general information when red, yellow, green, or blue do not apply. It often confirms that a system is energized or monitoring is active. 2. Actuators (Pushbuttons and Switches)

Help operators make fast, accurate decisions during normal use and emergencies. Why Engineers Search for the "IEC 60073 PDF" iec 60073 pdf

IEC 60073, titled "Basic and safety principles for man-machine interface, marking and identification - Coding principles for indicators and actuators," is published by the International Electrotechnical Commission. It standardizes the visual, acoustic, and tactile coding used to represent safety and operational states on control panels, machinery, and electrical installations. Why Standardized Coding Matters

The most referenced section of the IEC 60073 PDF is the color assignment matrix for indicator lights and pushbuttons. Colors are categorized by their safety and operational meanings. Indicator Lights (Displays and Pilot Lights) Explanation / Action Required Danger, immediate action required Fault, over-temperature, safety tripped YELLOW Impending critical condition, monitoring needed Overload warning, pressure limit approach GREEN Safe condition, normal operation System ready, safe to approach BLUE Action required by the operator Input required, reset command needed WHITE General information, no specific safety meaning Power on, cycle in progress Actuators (Pushbuttons) The is a foundational document for designing safe

Monitoring or intervention required to prevent a full system shutdown. Normal / Safe

IEC 60073 doesn't exist in a vacuum. It's part of a family of standards that work together to ensure complete and unambiguous safety signaling. A key example is , which specifies requirements for visual, acoustic, and tactile methods of indicating safety-related information. Its 2007 edition was formally adapted to align with IEC 60073, as well as with ISO 7010 (safety signs) and others. Used for general information when red, yellow, green,

For example, the standard dictates that a (button) should be used exclusively for stopping or emergency functions, while a green actuator implies starting or enabling a function. A flashing yellow light indicates a warning or abnormal condition requiring attention.

Buttons and switches should feature distinct physical geometries. Emergency stop buttons, for example, must utilize a large mushroom-head design that projects outward from the panel, making it easily distinguishable by touch and sight from standard flush-mount start buttons. 2.
