When visual signals are insufficient, acoustic signals provide critical alerts through pure tones, specific frequencies, or spoken messages. These are categorized by urgency and should be designed to be distinguishable from ambient factory noise. IEC 60073:2002

As a under IEC Guide 104, its principles are intended to be used consistently across all electrotechnical equipment to maintain a "common language" for safety. Core Coding Principles iec 60073 pdf

The standard, titled "Basic and safety principles for man-machine interface, marking and identification – Coding principles for indicators and actuators," is a foundational safety publication used globally to standardize how machines communicate with human operators. By establishing universal rules for visual, acoustic, and tactile signals, this standard ensures that an operator can immediately recognize the status of a process and react correctly, significantly reducing the risk of human error in industrial environments. Overview of IEC 60073 Core Coding Principles The standard, titled "Basic and

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). It applies to a wide range of hardware,

IEC 60073 mandates that coding principles be established early in the system design phase and remain consistent throughout a plant or process. It recommends using multiple "channels" of indication—such as combining color with shape or sound—to ensure clarity even if one sense is impaired (e.g., color blindness). 1.
