ISO 22760-3:2024/Amd 1:2026

Overview

ISO 22760-3:2024/Amd 1:2026 is an international amendment developed by the International Organization for Standardization (ISO), focusing on road vehicles utilizing Dimethyl Ether (DME) as a fuel. Specifically, this amendment addresses the 85% stop valve component in DME fuel systems. The update, published in 2026, modifies requirements for the type of fuel marking for these components, ensuring clearer identification and traceability within automotive fuel systems. The standard is intended to enhance safety, accuracy, and compliance in the use of DME fuel system parts, supporting global harmonization in the automotive industry.

Key Topics

• Component Marking Requirements
  The amendment strengthens marking guidelines for DME fuel system components, particularly the 85% stop valve. Markings are required to include:

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

• Additional Marking Recommendations
  To further facilitate safe use and traceability of DME components, the following are recommended:

  • Direction of flow (if necessary for installation)
  • Electrical ratings (as applicable)
  • Certification agency symbol
  • Type approval number
  • Serial number or date code
  • Reference to ISO 22760-3:2024

• Alignment with International Standards
  The amendment upholds ISO’s editorial rules and is closely aligned with the ISO/IEC Directives, supporting international consensus and regulatory compatibility.

Applications

• Automotive Manufacturers and Suppliers
  Road vehicle manufacturers and component suppliers benefit from this amendment by adopting standardized marking practices for DME 85% stop valves. Clear markings streamline quality assurance, facilitate recalls if needed, and help ensure components are suitable for their intended DME fuel application.

• Safety and Compliance
  By mandating explicit fuel type marking, the amendment improves safety in DME-powered vehicles. Correct identification of fuel system components minimizes the risk of improper installation or misuse, aligning with regulatory compliance and vehicle certification requirements.

• Maintenance and Service Operations
  Workshops, service centers, and technical professionals use marking information for maintenance, repairs, and audits. Enhanced traceability helps identify components quickly, verify authenticity, and track maintenance history.
