IEC 60073 is the international standard that sets the rules for how we use colors, shapes, sounds, and touch to communicate with machines iec 60073 pdf

. Think of it as the "universal language" for control panels and industrial equipment to ensure operators stay safe and systems run smoothly. iTeh Standards Core Coding Principles

The standard focuses on three primary methods of providing information to a human operator: iTeh Standards Visual Coding

: Colors (red, green, yellow, etc.), flashing lights, and standardized shapes. Acoustic Coding

: Different tones or frequencies of sound to indicate urgency. Tactile Coding

: Physical shapes or textures of buttons so you can "feel" which one is which. iTeh Standards Visual Indicator Guide (Lights & Beacons)

The most common application is color-coding indicator lamps. According to D G Controls , these are the standard meanings: Safety Meaning Process State Emergency or Fault (e.g., DC supply failure) Abnormal condition; requires attention Normal operation; "Go" status Action required by the operator (e.g., Reset) No specific safety meaning; general status Actuator Guide (Buttons & Switches) For buttons (actuators), the color often dictates the of command you are giving: : Used exclusively for Stop or Emergency Stop functions. : Typically used for Start or "On" functions. Yellow/Amber

: Often used for "Reset" or to intervene in an abnormal condition. : Mandatory actions, like a manual reset after a fault. Accessibility Tips Positioning

: To help color-blind operators, the standard recommends consistent positioning (e.g., Red at the top, Amber in the middle, Green at the bottom).

: A flashing light is more urgent than a steady one. It typically means "take action now" or "acknowledgment required". Once acknowledged, the signal often turns steady. ИС «МЕГАНОРМ» Accessing the Full PDF IEC 60073: Red for DC Fail Indicators | PDF - Scribd

IEC 60073 is the international standard for coding principles for indicators and actuators. It defines how colors, shapes, and sounds should be used to communicate safety and status information on control panels and machines. 💡 Core Purpose

The standard aims to ensure that human-machine interfaces (HMIs) are consistent and intuitive. By following these rules, manufacturers reduce the risk of human error, as operators don't have to relearn what a "Red" button or a "Green" light means when switching between different machines. 🎨 Color Meanings (Indicators) Overview of IEC 60073 IEC 60073 is an

The standard assigns specific meanings to colors to indicate the state of a process or equipment:

🔴 Red: Danger. Indicates an emergency or a condition requiring immediate action (e.g., a fault or hazardous state).

🟡 Yellow: Abnormal. Warning of a condition that could become dangerous if not corrected.

🟢 Green: Normal. Indicates a safe condition or that a process is ready to start.

🔵 Blue: Mandatory. Indicates a state that requires a specific action by the operator (e.g., "reset required").

⚪ White / Grey / Black: Neutral. Used for general information where no specific safety meaning is attached. Coding for Actuators (Buttons)

For push-buttons and controls, the standard provides rules to prevent accidental activation:

Emergency Stop: Must be Red and should ideally be a mushroom-head shape. Start / On: Typically Green, White, or Grey. Stop / Off: Typically Red, Black, or Grey. Reset: Usually Blue, White, or Grey. 🛠️ Visual & Acoustic Coding

Beyond color, IEC 60073 covers other ways to convey information:

Flashing Lights: Used to draw higher attention (e.g., a flashing red light is more urgent than a steady one).

Shapes: Geometric symbols (circles, squares, triangles) can be used to help color-blind users or to provide redundancy. Functional Safety : The standard emphasizes the importance

Acoustic Signals: Specific tones or frequencies can be used to signal warnings or status changes. 📂 How to Access the PDF

IEC 60073: A Deep Dive into the Language of Operator Interfaces

Q4: Does IEC 60073 cover touchscreen HMIs?

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

1. Introduction: The Need for a Universal Interface Language

In any industrial, medical, or consumer control environment, a human operator must interact with machinery. This interaction relies heavily on visual, auditory, and tactile cues—lights, buzzers, and buttons. Without standardization, a flashing red light could mean “emergency stop” on one machine and “normal operation” on another, leading to catastrophic errors.

IEC 60073 (full title: Basic and safety principles for man-machine interface, marking and identification – Coding principles for indicators and actuators) is the international standard that establishes the fundamental coding principles for these indicators (lights/displays) and actuators (buttons/switches). It answers a simple but critical question: What color, flash rate, or sound means what action?

Note: 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.

5. Relationship with Other Standards

IEC 60073 is the horizontal standard; it feeds into:

  • IEC 60204-1 – Safety of machinery – electrical equipment (uses same colors for pushbuttons).
  • IEC 60947-5-5 – Emergency stop devices (refers to 60073 for color coding).
  • ISO 13850 – Emergency stop – functional requirements.
  • ISO 7010 – Safety signs (graphical symbols complement colors).
  • IEC 61310-2 – Marking and identification of actuators (operational layer).

4.3 Auditory Coding

When visual is insufficient (noisy environment, operator not looking), sounds provide coded meaning:

| Sound Type | Meaning | |------------|---------| | Continuous steady tone | General attention (e.g., start-up warning) | | Intermittent (beep, 1 Hz) | Normal confirmation (e.g., keypress) | | Fast intermittent (2+ Hz) | Urgent warning, approaching danger | | Wailing / rising pitch | Emergency evacuation or critical fault | | Chime / pleasant tone | Success, normal completion |

Safety note: Auditory codes must be distinct from background noise and from other alarms (e.g., fire vs. machine fault).
