ISO 12619-2:2014 specifies performance and general test methods for compressed gaseous hydrogen (CGH2) and hydrogen/natural gas blends fuel system components, intended for use on the types of motor vehicles defined in ISO 3833. This part of ISO 12619-2:2014 is applicable to vehicles using CGH2 in accordance with ISO 14687‑1 or ISO 14687‑2 and hydrogen/natural gas blends using natural gas in accordance with ISO 15403‑1 and ISO/TR 15403‑2. It is not applicable to the following: -liquefied hydrogen (LH2) fuel system components; -fuel containers; -stationary gas engines; -container mounting hardware; -electronic fuel management; -refuelling receptacles.

Abstract

Overview

ISO 12619-2:2014 specifies performance and general test methods for compressed gaseous hydrogen (CGH2) and hydrogen/natural gas blend fuel system components used on road vehicles (as defined in ISO 3833). The standard defines laboratory and field-representative test procedures to verify component integrity, leakage performance, material compatibility and durability for systems using CGH2 (per ISO 14687) or hydrogen/natural gas blends (per ISO 15403). It explicitly excludes liquefied hydrogen (LH2) components, fuel containers, stationary gas engines, mounting hardware, electronic fuel management and refuelling receptacles.

Key topics and technical requirements

General test conditions - default room temperature (≈20 °C ±5 °C), dry test gases and specified dew‑point controls; tests performed by qualified personnel.
Hydrostatic strength - pressurization and burst/failure recording; post‑durability strength retention criteria.
Leakage testing - external and internal leakage methods; immersion or helium accumulation methods; typical acceptance leak rate thresholds.
Mechanical resistance - excess torque resistance for threaded fittings and bending moment tests to verify structural integrity under load.
Durability cycling - continued operation tests including room, high and low temperature cycling to assess life performance.
Environmental ageing and compatibility - corrosion (salt spray), oxygen and ozone ageing, non‑metallic immersion, vibration, and electrical overvoltage exposure.
Material compatibility - procedures for evaluating metallic and non‑metallic materials with hydrogen (including embrittlement concerns) and brass compatibility.
Special exposures - pre‑cooled hydrogen exposure tests and insulation resistance verification.

Practical applications and who uses this standard

ISO 12619-2 is used by:

OEMs and vehicle manufacturers integrating hydrogen or H2/CNG blend fuel systems into road vehicles.
Component suppliers (valves, regulators, hoses, fittings, sensors) to demonstrate performance and regulatory readiness.
Test laboratories and certification bodies conducting conformity, type approval and safety testing for hydrogen fuel system components.
R&D and materials engineers assessing hydrogen compatibility, durability and failure modes for new designs.

Benefits include improved safety assurance, consistent test methods across suppliers, and clearer acceptance criteria for hydrogen fuel system commercialization.
