Full title and description

Road vehicles — Compressed gaseous hydrogen (CGH2) and hydrogen/natural gas blends fuel system components — Part 1: General requirements and definitions. This part of ISO 12619 specifies general requirements, definitions, basic design principles and requirements for instructions and markings for CGH2 and hydrogen/natural gas blend fuel system components intended for use on road vehicles (types defined in ISO 3833).

Abstract

ISO 12619-1:2014 sets out general requirements and terminology for compressed gaseous hydrogen (CGH2) and hydrogen/natural gas blend fuel system components for road vehicles. It is applicable to vehicles using CGH2 (in accordance with ISO 14687-1/2) and hydrogen/natural gas blends (in accordance with ISO 15403-1 and ISO/TR 15403-2). The standard also lists items that are excluded from its scope (for example, liquefied hydrogen components, fuel containers, stationary gas engines, container mounting hardware, electronic fuel management and refuelling receptacles).

General information

• Status: Published — International Standard (confirmed at review).
• Publication date: 11 June 2014.
• Publisher: International Organization for Standardization (ISO).
• ICS / categories: 43.060.40 (Fuel systems).
• Edition / version: Edition 1 (2014).
• Number of pages: 8 (as published by ISO; some national/adopted versions list differing pagination/formatting).

Scope

Defines general requirements, definitions and design principles for CGH2 and hydrogen/natural gas blend fuel system components intended for road vehicles defined in ISO 3833. Specifies requirements for component instructions and markings and establishes applicability limits: it applies to gaseous hydrogen and hydrogen/natural gas blends (per referenced fuel quality standards) and excludes liquefied hydrogen components, fuel containers, stationary gas engines, container mounting hardware, electronic fuel management and refuelling receptacles.

Key topics and requirements

• Definitions and terminology specific to CGH2 and H2/NG blend fuel system components.
• General design principles for components intended for compressed gaseous hydrogen and hydrogen/natural gas blends.
• Requirements for instructions, markings and identification of components used in the fuel system.
• Applicability constraints referencing fuel quality and related standards (ISO 14687 series for hydrogen quality; ISO 15403 series for natural gas).
• Clear exclusions (e.g., LH2, fuel containers, refuelling receptacles) to avoid overlap with other standards and regulations.

Typical use and users

Used by automotive OEMs, fuel-system component manufacturers, design and safety engineers, test laboratories, certification bodies and regulators involved in vehicle fuel‑system design and type‑approval for vehicles using compressed gaseous hydrogen or hydrogen/natural gas blends. It serves as a high-level normative reference when developing component-specific test standards or parts in the ISO 12619 series.

Related standards

ISO 12619-1 is the introductory/definitions part of a multi‑part ISO 12619 series covering specific components and tests (examples: Part 2 — Performance and general test methods; Part 4 — Check valve; Part 5 — Manual cylinder valve; Part 6 — Automatic valve; Parts 8, 9, 10, 11, 14 — pressure indicator, pressure relief valve, pressure relief device, excess flow valve, flexible fuel line, etc.). It also references vehicle definitions in ISO 3833 and fuel quality standards such as ISO 14687 (hydrogen) and ISO 15403 (natural gas).

FAQ

Q: What is this standard?

A: ISO 12619-1:2014 is the first part of the ISO 12619 series that establishes general requirements, definitions and basic design/marking/instruction requirements for compressed gaseous hydrogen (CGH2) and hydrogen/natural gas blend fuel system components for road vehicles.

Q: What does it cover?

A: It covers terminology, general requirements and design principles for CGH2 and H2/NG‑blend fuel system components and specifies requirements for instructions and markings. It does not provide detailed test methods for many specific components (those are addressed in other parts of the ISO 12619 series).

Q: Who typically uses it?

A: Automotive manufacturers, component suppliers, design and safety engineers, testing and certification laboratories, and regulatory or type‑approval authorities working with gaseous hydrogen or H2/NG blend vehicle fuel systems.

Q: Is it current or superseded?

A: Published on 11 June 2014 (Edition 1). The ISO record shows the standard was reviewed/confirmed during the normal review cycle (the ISO lifecycle indicates periodic review and confirmation), so the 2014 edition remains the active/confirmed edition unless a later revision or withdrawal is published by ISO. Users should check their national standards body or the ISO catalogue for any subsequent revisions or amendments before relying on the text for certification or legal compliance.

Q: Is it part of a series?

A: Yes — ISO 12619 is a multi‑part series. Part 1 provides general requirements and definitions; other parts (published 2014–2017) address performance, test methods and specific components such as check valves, manual and automatic valves, pressure relief devices, pressure indicators, excess flow valves, flexible fuel lines and more. Consult the ISO 12619 series index for the full list of published parts.

Q: What are the key keywords?

A: Compressed gaseous hydrogen (CGH2), hydrogen/natural gas blends, fuel system components, road vehicles, definitions, design principles, instructions and markings, ISO 3833, ISO 14687, ISO 15403.
