ISO 6727:2021/Amd 1:2024 PDF

Overview

ISO 6727:2021/Amd 1:2024 is an essential international standard issued by the International Organization for Standardization (ISO), focused on road vehicles, specifically motorcycles and mopeds. This amendment updates the 2021 third edition standard on symbols for controls, indicators, and tell-tales applicable to these vehicles. The updated symbols enhance clarity and consistency in vehicle interfaces, promoting safer and more intuitive user interactions.

The standard is developed by ISO Technical Committee ISO/TC 22, Subcommittee SC 38, and ensures harmonized graphic symbols for motorcycle and moped controls and indicators worldwide. These symbols help riders quickly understand vehicle states and controls, reducing confusion and enhancing road safety.

Key Topics

• New and updated symbols for vehicle controls and indicators: This amendment introduces a series of new symbols covering advanced vehicle systems such as:

  • Acoustic Vehicle Alerting System (AVAS) for quiet vehicles
  • Hill holding system status (active, off, or malfunction)
  • Hill descent control system indicators
  • Anti-lock Brake System (ABS) status for rear brakes
  • Stability control system status
  • Forward collision warning and lane departure warning systems
  • Obstacle warning and lane keeping assistance symbols

• Standardized colors for tell-tale lights: The amendment specifies precise colors for different status indicators to ensure rapid recognition:

  • Amber (yellow) for warnings and failures
  • Green or white for active or ready functions

• Symbol variations and alternatives: Symbols may include letters or words (e.g., "H" for hill holding, "OFF" for function non-availability) alongside graphic elements to convey clear meanings.

• Use of ISO/IEC registration numbers: Each symbol aligns with corresponding ISO/IEC registration (ISO 7000 series), linking to a globally recognized symbol database.

Applications

ISO 6727:2021/Amd 1:2024 is crucial for:

• Vehicle manufacturers: Ensuring design and integration of standardized symbols on motorcycle and moped dashboards, control panels, and user manuals, enhancing user experience and regulatory compliance.

• Safety and regulatory bodies: Facilitating uniform safety communication and compliance verification in global markets.

• Technological systems development: Assisting developers of modern motorcycle features like collision warning, stability control, and hill descent assist with standardized symbol usage.

• Rider education and training: Providing consistent visual aids for teaching vehicle control recognition and safety.

Related Standards

• ISO 7000 series (Graphical symbols for use on equipment): Provides the registration and definitions for many symbols referenced in this amendment.

• ISO 2575 (Symbol language for controls, indicators and tell-tales): Specifies standardized rules for symbol depiction and usage including supplementary text options.

• ISO/IEC Directives Part 1 & 2: Guides the drafting, approval, and maintenance processes for ISO standards, ensuring consistency and clarity.

ISO 6727:2021/Amd 1:2024 sets a vital foundation for uniform and easily recognizable control and indicator symbols on motorcycles and mopeds, driving forward international safety and usability standards in the evolving landscape of road vehicles. For more information, visit ISO official website.
