ISO 22760-4:2024/Amd 1:2026

Overview

ISO 22760-4:2024/Amd 1 is an important amendment to the international standard for road vehicle components related to Dimethyl Ether (DME) fuel systems. Specifically, this amendment focuses on Part 4: Level Indicator, which defines the requirements for level indicators used in DME fuel system components. Issued by ISO Technical Committee 22/Subcommittee 41, this document ensures enhanced clarity and consistency in the marking and identification of these components for improved traceability and safety in DME-fueled road vehicles.

Key Topics

• Scope and Focus
  This amendment applies to the level indicators used in DME fuel systems for road vehicles. It updates marking requirements to make the type of fuel mandatory, reflecting the critical nature of component identification for safety and maintenance.

• Marking Requirements
  The amendment mandates that level indicators must include clear markings to provide traceability of the component. Required markings include:

  • Manufacturer’s or agent’s name, trademark, or symbol
  • Model designation or part number
  • Working pressure or working pressure and temperature range
  • Type of fuel (now mandatory according to Amendment 1)

• Recommended Marking Additions
  While not mandatory, the following markings are recommended to aid in installation and certification processes:

  • Direction of fuel flow (if relevant for installation)
  • Electrical ratings, if applicable
  • Certification agency symbol
  • Type approval number
  • Serial number or date code
  • Reference to ISO 22760-4 standard

• Component Identification
  For multi-part components, the information should be traceable via suitable identification codes on at least one part to ensure integrity and compliance throughout the vehicle’s lifecycle.

Applications

• Road Vehicle Safety and Reliability
  By specifying precise marking requirements on DME fuel system level indicators, ISO 22760-4:2024/Amd 1 enhances vehicle safety by ensuring accurate identification of components. This supports proper maintenance, servicing, and replacement.

• Compliance and Certification
  The amendment assists manufacturers and regulatory bodies in achieving conformity with international standards, facilitating smoother type approval and certification procedures for DME fuel systems.

• Traceability in Manufacturing and Supply Chains
  Clear and standardized marking facilitates traceability within the supply chain, helping manufacturers track product batches and enabling quicker responses in case of recalls or defects.

• Support for Alternative Fuels Integration
  As DME is increasingly recognized as a sustainable alternative fuel, standards like ISO 22760-4:2024/Amd 1 play a key role in integrating DME technologies safely into road vehicles worldwide.

Related Standards

• ISO 22760 Series
  Part of the ISO 22760 series covering various components of DME fuel systems in road vehicles. Other parts address different components such as pumps, valves, and connectors used in DME fuel systems.

• ISO/TC 22/SC 41 Standards
  Developed by ISO Technical Committee 22, Subcommittee 41, which specializes in gaseous fuel technologies for road vehicles. Subcommittee 41 is responsible for standards across multiple alternative and gaseous fuel systems.

• ISO/IEC Directives
  The standard follows the editorial and procedural guidelines outlined in ISO/IEC Directives, Parts 1 and 2, ensuring consistency and quality in standard development and maintenance.
