Full title and description

ISO 12619-3:2014 — Road vehicles — Compressed gaseous hydrogen (CGH2) and hydrogen/natural gas blends fuel system components — Part 3: Pressure regulator. This International Standard specifies the tests and minimum requirements for the pressure regulator used as a component of CGH2 and hydrogen/natural-gas-blend vehicle fuel systems.

Abstract

ISO 12619-3:2014 defines performance tests and requirements for pressure regulators intended for use on the types of motor vehicles defined in ISO 3833. It is written for systems using compressed gaseous hydrogen (CGH2) and hydrogen/natural gas blends (with fuel quality references to ISO 14687 and ISO 15403 documents) and explicitly excludes items such as liquefied hydrogen components, fuel containers, stationary gas engines, certain mounting hardware and refuelling receptacles.

Scope

This part of ISO 12619 applies to the pressure regulator component of vehicle fuel systems using compressed gaseous hydrogen (CGH2) or hydrogen/natural gas blends. It specifies the types of tests and performance requirements that such regulators must meet for safe and reliable operation on motor vehicles (as defined by ISO 3833), and it excludes items such as liquefied-hydrogen components, fuel storage containers, stationary engines, electronic fuel management systems and refuelling receptacles.

Key topics and requirements

• Functional performance requirements for pressure regulation and set/relief behaviour.
• Type and endurance tests to demonstrate durability under vehicle service conditions (pressure cycling, temperature extremes, vibration).
• Hydrogen compatibility of materials and prevention of permeation/leakage.
• Leak tightness and safety-related performance criteria.
• Marking, identification and required documentation / technical information for the component.
• Conformance tests and acceptance criteria for production and qualification testing.

Typical use and users

Primary users include vehicle OEMs, hydrogen-fuel-system and component manufacturers, certification and test laboratories, hydrogen-vehicle integrators, and regulatory bodies specifying or verifying component compliance. The standard is used during component design, type approval/qualification testing, and supplier assessment for hydrogen-capable vehicles.

Related standards

ISO 12619-3 is part of the broader ISO 12619 series addressing individual CGH2 and hydrogen/natural-gas-blend fuel-system components (e.g., Parts 1, 2, 4–16 covering general requirements, test methods and specific components such as valves, lines and filters). It is also referenced alongside fuel-quality and system standards such as ISO 14687 (hydrogen fuel quality), ISO 15403 (natural gas quality for vehicle fuels) and related vehicle/system test standards.

FAQ

Q: What is this standard?

A: ISO 12619-3:2014 is the part of the ISO 12619 series that specifies tests and performance requirements for pressure regulators used in compressed gaseous hydrogen (CGH2) and hydrogen/natural-gas-blend vehicle fuel systems.

Q: What does it cover?

A: It covers required tests, performance criteria, and documentation/marking for pressure regulators intended for use on motor vehicles running on CGH2 or hydrogen/natural-gas blends; it also lists explicit exclusions (for example, components related to liquefied hydrogen and fuel containers are outside its scope).

Q: Who typically uses it?

A: Vehicle manufacturers (OEMs), component suppliers, testing and certification laboratories, system integrators and regulatory authorities involved in hydrogen vehicle safety and component approval.

Q: Is it current or superseded?

A: ISO 12619-3:2014 was published in June 2014 and has at least one formal amendment published in 2016 (ISO 12619-3:2014/Amd 1:2016). ISO records show the published standard and its amendment; users should check the ISO catalogue or their national standards body for the most current status and any later confirmations or revisions.

Q: Is it part of a series?

A: Yes — ISO 12619 is a multipart series addressing individual fuel-system components for vehicles using CGH2 and hydrogen/natural-gas blends (Parts 1–16 cover general requirements, test methods and specific components such as valves, lines, filters and indicators).

Q: What are the key keywords?

A: Pressure regulator; CGH2; hydrogen/natural gas blends; fuel system components; hydrogen compatibility; component testing; ISO 12619.
