Overview
ISO 22760-9:2024/Amd 1 is an amendment to the international standard governing Dimethyl Ether (DME) fuel system components used in road vehicles. Specifically, this part focuses on the Pressure Relief Device (PRD), a critical safety component designed to protect DME fuel systems from overpressure conditions. Published by ISO in 2025 under ISO/TC 22/SC 41, this amendment refines the marking requirements to enhance traceability and safety compliance.
The standard is essential for manufacturers, engineers, and regulatory bodies involved in the design, production, inspection, and maintenance of DME fuel systems, ensuring uniform quality and safety measures worldwide.
Key Topics
Pressure Relief Device (PRD) Requirements
The document addresses specifications related to PRDs, which release excess pressure in the DME fuel system to prevent component failure or hazards.Mandatory Fuel Type Marking
The amendment makes it compulsory to mark the PRD with the type of fuel it is designed for, ensuring correct application and identification.Comprehensive Component Marking
To improve traceability and installation accuracy, the following markings are required on the PRDs:- Manufacturer’s or agent’s name, trademark, or symbol
- Model designation or part number
- Working pressure and temperature range
- Type of fuel (mandatory)
- Recommended additional markings:
- Direction of flow (if necessary)
- Electrical ratings (if applicable)
- Certification agency symbol
- Type approval number
- Serial number or date code
- Reference to ISO 22760-9 standard
Traceability and Safety
These marking requirements facilitate easier identification, quality assurance, and compliance checks, contributing to safer DME fuel system operation in road vehicles.
Applications
Automotive Manufacturing
Ensuring that PRDs installed in DME fuel systems meet consistent safety standards helps manufacturers produce reliable and safe vehicles.Vehicle Maintenance and Inspection
Technicians use the standardized markings to verify component authenticity, working parameters, and proper installation, supporting effective maintenance and safety audits.Regulatory Compliance
Authorities relying on ISO standards can uniformly assess compliance for vehicles using DME fuel systems, aiding regulatory oversight and certification.Aftermarket Components and Replacement Parts
Marking standardization assists suppliers and end-users in verifying correct replacement parts, preventing mismatches that could compromise safety.
