Full title and description

Road vehicles — Compressed gaseous hydrogen (CGH2) and hydrogen/natural gas blends fuel system components — Part 2: Performance and general test methods. This part of ISO 12619 specifies performance requirements and general test methods for fuel-system components intended for use with compressed gaseous hydrogen and hydrogen/natural-gas blends in road vehicles (vehicle types as defined in ISO 3833).

Abstract

ISO 12619-2:2014 defines test procedures and performance criteria for CGH2 and hydrogen/natural-gas-blend fuel system components used on road vehicles. It establishes functional, leakage, pressure, endurance and compatibility checks and states applicability conditions (vehicles using hydrogen per ISO 14687 and hydrogen/natural gas blends per ISO 15403). The part excludes components such as liquefied-hydrogen systems, fuel containers and stationary gas engines. An amendment to this part (Amd 1:2016) updates specific test details.

Scope

This part of ISO 12619 applies to fuel-system components for road vehicles that use compressed gaseous hydrogen (CGH2) and hydrogen/natural-gas blends. It specifies performance and general test methods to verify component function, pressure integrity, leakage behaviour, endurance and basic compatibility with hydrogen or hydrogen blends. The standard is applicable where hydrogen quality and composition meet the referenced fuel-quality standards (ISO 14687 series and ISO 15403), and it is intended for components used on vehicle types defined by ISO 3833. It does not apply to liquefied-hydrogen (LH2) components, fuel containers (pressure receptacles), stationary gas engines, or certain ancillary hardware unless explicitly stated.

Key topics and requirements

• Performance test methods for functional behaviour of fuel-system components under expected operating pressures and temperatures (including endurance cycling and operational response).
• Leakage and pressure-integrity criteria and test procedures to verify safety under normal and fault conditions.
• Compatibility checks and requirements for materials and components exposed to CGH2 and hydrogen/natural-gas blends.
• Reference to hydrogen and natural gas fuel-quality requirements (ISO 14687 and ISO 15403) as part of the applicability conditions for tests.
• Defined exclusions and limits of applicability (e.g., LH2 systems, fuel containers, stationary engines).
• Test instrumentation, conditioning and reporting expectations to enable reproducible component evaluation.
• Updates and clarifications introduced via Amendment 1 (2016) to specific test details.

Typical use and users

Primary users are automotive and heavy‑vehicle manufacturers, fuel-system component designers and suppliers, test laboratories, certification bodies and regulators involved in hydrogen vehicle safety and conformity assessment. The standard is used during component development, type-approval testing, supplier qualification and third-party conformity testing for CGH2 and hydrogen-blend fuel-system components.

Related standards

This part is one element of the ISO 12619 series (other parts cover general requirements and many specific components such as pressure regulators, check valves, manual cylinder valves, automatic valves, pressure-relief devices, fittings, lines and filters). It is intended to be used alongside: - ISO 12619-1 (General requirements and definitions), - ISO 12619-3 (Pressure regulator), - ISO 12619-4 (Check valve), - ISO 12619-5 (Manual cylinder valve), - ISO 12619-6, -9, -11 to -16 (component-specific parts), and with fuel-quality and vehicle-definition standards such as ISO 14687 (hydrogen fuel quality), ISO 15403 (natural gas fuel designation) and ISO 3833 (vehicle type definitions).

FAQ

Q: What is this standard?

A: ISO 12619-2:2014 is an international standard that specifies performance requirements and general test methods for fuel‑system components intended for use with compressed gaseous hydrogen (CGH2) and hydrogen/natural‑gas blends in road vehicles.

Q: What does it cover?

A: It covers test procedures and performance criteria (functional, pressure, leakage, endurance and compatibility checks) for individual fuel‑system components used with CGH2 and hydrogen/natural‑gas blends. It defines applicability conditions and lists certain exclusions (for example, LH2 systems and fuel containers).

Q: Who typically uses it?

A: Vehicle OEMs, component suppliers (valves, regulators, fittings, lines, filters), independent test laboratories, type‑approval and certification bodies, and regulatory authorities responsible for vehicle fuel‑system safety and compliance.

Q: Is it current or superseded?

A: ISO 12619-2:2014 is a published (active) part of the ISO 12619 series; an amendment (ISO 12619-2:2014/Amd 1:2016) exists to update specific items. The ISO record shows routine review/confirmation activity for the series. Users should check national/ISO catalogues for the latest confirmation or amendments before applying the standard.

Q: Is it part of a series?

A: Yes — ISO 12619 is a multi‑part series addressing CGH2 and hydrogen/natural‑gas blend fuel‑system components; Part 1 covers general requirements and definitions and subsequent parts cover specific components (pressure regulator, check valve, manual/automatic valves, PRVs, fittings, lines, filters, etc.).

Q: What are the key keywords?

A: Hydrogen, CGH2, hydrogen/natural‑gas blends, fuel system components, performance test methods, pressure integrity, leakage, ISO 12619.
