Overview
ISO 12619-13:2017 specifies tests and requirements for rigid fuel lines in stainless steel used in road-vehicle fuel systems carrying compressed gaseous hydrogen (CGH2) and hydrogen/natural gas blends. The standard applies to vehicles as defined in ISO 3833 and to fuels meeting ISO 14687 (hydrogen) and ISO 15403 (natural gas) product specifications. It does not apply to liquefied hydrogen (LH2) components, fuel containers, fuel cell vehicles, refuelling receptacles, electronic fuel management or certain mounting hardware. All pressure references are gauge pressures unless stated otherwise.
Key topics and technical requirements
- Material & construction
- Rigid fuel line must be seamless, cold-worked austenitic stainless steel tube in compliance with ISO 1127.
- Construction and tolerances follow ISO 12619-1 and ISO 12619-2 where applicable.
- Marking & traceability
- Mandatory markings: manufacturer/agent identification, model/part number and temperature range.
- Recommended: flow direction, fuel type, electrical ratings, certification symbol, type approval number, serial/date code, and reference to ISO 12619-13:2017.
- Required tests
- Hydrostatic strength: test at four times the working pressure (higher than other series parts to allow margin for damage/abrasion).
- Continued operation: cyclic endurance testing for 100 000 cycles followed by hydrostatic retest.
- Bending: bend over a mandrel (per ISO 12619-2) into a U-shape, close ends, perform hydrostatic test, then leakage test.
- Other referenced test procedures (e.g., leakage, corrosion, ageing, automotive fluids) are defined in ISO 12619-2; applicability is shown in the standard’s test table.
Applications and who uses it
ISO 12619-13:2017 is intended for:
- OEMs and tier‑1/2 component manufacturers designing and producing rigid stainless-steel fuel lines for CGH2 and hydrogen/natural gas blend vehicles.
- Design and validation engineers specifying material, assembly, and test methods for hydrogen fuel systems.
- Test laboratories performing hydrostatic, cyclic, bending and leakage evaluations to support type approval and quality control.
- Regulatory and certification bodies assessing compliance for on‑vehicle gaseous hydrogen fuel system components. Practical uses include component design validation, production quality assurance, supplier specifications, and type‑approval documentation.

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out
through ISO technical committees. Each member body interested in a subject for which a technical
committee has been established has the right to be represented on that committee. International
organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.
