Full title and description
St ISO 12619-16-2017 — Road vehicles — Compressed gaseous hydrogen (CGH2) and hydrogen/natural gas blends fuel system components — Part 16: Fittings. This International Standard specifies tests and requirements for fittings used in CGH2 and hydrogen/natural gas blend fuel system components intended for use on motor vehicles (types defined in ISO 3833).
Abstract
ISO 12619-16:2017 defines the required performance checks and test criteria for fittings in compressed gaseous hydrogen (CGH2) and hydrogen/natural gas blend vehicle fuel systems. It sets applicability boundaries (vehicles using CGH2 per ISO 14687-1/2 and hydrogen/natural gas blends per ISO 15403 series) and lists components and application areas excluded from the part. References to pressure are gauge pressures unless otherwise specified.

Scope
ISO 12619-16:2017 applies to fittings that form part of compressed gaseous hydrogen (CGH2) and hydrogen/natural gas blend fuel system components for the types of road vehicles defined in ISO 3833. It applies where the vehicle fuel quality meets the requirements of ISO 14687 (hydrogen) or ISO 15403 (natural gas) as appropriate. The standard is not applicable to liquefied hydrogen (LH2) components, fuel containers, stationary gas engines, container mounting hardware, electronic fuel management, refuelling receptacles, or fuel cell vehicles. The document uses gauge pressure references unless otherwise stated.
Key topics and requirements
- Definition of applicability for fittings in CGH2 and hydrogen/natural gas blend vehicle fuel systems.
- Performance and functional test requirements tailored for fittings (examples: leak tightness, burst/overpressure resistance, cyclic pressure endurance, mechanical strength, sealing performance and hydrogen compatibility / resistance to hydrogen-induced degradation).
- Test conditions and acceptance criteria referenced to relevant fuel quality standards (ISO 14687 and ISO 15403 series).
- Clear exclusions (LH2 systems, fuel containers, refuelling receptacles, fuel cell vehicles, etc.).
- Notes on interpretation: gauge pressure conventions and allowance to test miscellaneous components by appropriate functional tests.
Typical use and users
Primary users include vehicle OEMs, fuel-system component and fitting manufacturers, design and test laboratories, certification and homologation bodies, hydrogen infrastructure integrators, and regulators. Typical uses are component design validation, type-approval testing, supplier qualification, and conformity assessment for fittings intended for use in CGH2 and hydrogen/natural gas blend vehicle fuel systems.
Related standards
ISO 12619-16 is one part of the ISO 12619 series covering fuel system components for CGH2 and hydrogen/natural gas blends. Closely related documents include other parts of ISO 12619 (for example parts addressing pressure relief devices and flexible fuel lines), ISO 14687-1 / ISO 14687-2 (hydrogen fuel quality), ISO 15403-1 / ISO/TR 15403-2 (natural gas fuel quality), and ISO 3833 (vehicle type definitions). Users commonly apply these documents together when specifying, testing and approving hydrogen/NG-hydrogen blend fuel system components.
