Iec 60073 Pdf Updated Jun 2026

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

The colors of buttons that initiate actions follow a complementary logic, emphasizing safety and operational intent:

IEC often provides the table of contents , scope , and normative references for free on their website.

Standardization ensures that operators can rapidly recognize conditions and actuator positions across different systems. iTeh Standards Visual Indicators (Color Coding): Emergency, Danger, or Fault (e.g., DC supply failure). 🟡 Amber/Yellow: Abnormal condition or Warning. 🟢 Green: Safe, Normal, or "Go" (indicates the system is ready). 🔵 Blue: Mandatory action (e.g., "reset required"). ⚪ White: General information or auxiliary status. Flashing Rates: Standardizes attention-grabbing signals. Normal Flashing: 1.4 Hz to 2.8 Hz (used for immediate attention). Slow Flashing:

Warning, abnormal condition, or attention required. (e.g., "Temperature too high"). iec 60073 pdf

Yes, indirectly. Virtual buttons on an HMI should follow the same color meanings. However, tactile coding does not apply to touchscreens.

The standard outlines several key principles for HMI design, including:

Reserved exclusively for stopping, de-energizing, or emergency shutdown functions.

The primary objective of the standard is to increase workplace safety and operational efficiency by making human-machine interfaces (HMIs) intuitive, unambiguous, and consistent across different manufacturers and countries. Core Principles of Coding in HMIs The standard, titled "Basic and safety principles for

is the international standard that governs the coding principles for indicators and actuators. It establishes a universal visual and tactile language for machine interfaces, ensuring that operators worldwide can understand equipment states instantly and react safely during emergencies. This comprehensive guide explores the core principles of IEC 60073, its color and behavior assignments, and how to utilize the official PDF document for engineering and compliance. What is IEC 60073?

Defines for indicators (lights, displays) and actuators (buttons, switches) used in electrical equipment, ensuring safety and consistent interpretation across industries.

The standard breaks down interface coding into three primary modalities: visual (color, flashing), acoustic (sound intervals), and tactile (shapes, textures). 1. Color Coding for Indicator Lights

IEC 60073 is an international standard titled " " In simpler terms, it establishes the universal "language" used for communication between a machine and its human operator. It provides general rules for assigning specific meanings to visual (lights, screens), acoustic (beeps, alarms), and tactile (vibration, surface texture) signals. 🟢 Green: Safe, Normal, or "Go" (indicates the

Specifies the preferred colors and shapes for basic control functions to prevent accidental activation or confusion during shutdowns. Accessing the Standard

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

IEC 60073 provides the universal rules for assigning meanings to visual, acoustic, and tactile signals. Whether you are designing a simple push-button or a complex SCADA screen, this standard ensures that an operator can immediately recognize a machine's state and know exactly how to respond.
