Iec 60073 Pdf Now

IEC 60073 is often confused with IEC 60445 (terminal markings) or IEC 61310 (safety of machinery – indication, marking, actuation). While related, IEC 60073 is the foundational “color and sense” code.

This acoustic coding is particularly crucial in environments where visual signals may be obscured or for operators who may not have direct line-of-sight to indicators.

Used exclusively for stopping a machine, shutting down power, or emergency stops.

Used to initiate normal operation, start, or energize a system.

Bookmark the official IEC page, request a quote from ANSI, and invest in safety. The price of the standard is negligible compared to the cost of a single human error.

Control panels on machinery must follow IEC 60073 color assignments to ensure consistent interpretation across international operations. For example, motor starter switches universally use red for STOP (aligning with traffic lights) and green for START or GO.
