Full title and description

St ISO 19880-2-2025 — ISO 19880-2:2025, Gaseous hydrogen — Fuelling stations — Part 2: Dispensers and dispensing systems. This part of the ISO 19880 series specifies safety requirements and test methods for hydrogen dispensers and dispensing systems used to transfer compressed hydrogen to vehicles (up to the H70 pressure class designation).

Abstract

This standard defines safety requirements and test methods for components and systems that enable the transfer of compressed gaseous hydrogen to vehicles via a hydrogen dispenser. It covers dispenser configurations ranging from a complete dispenser cabinet to minimal component sets integrated with other station systems, and includes user/vehicle interfaces, metering and sensors, cooling units, control systems and fuelling hose assemblies. The document references ISO 19880-1 for additional fuelling-protocol and station-level requirements and provides specific cross-references to other parts of the series for individual components.

Scope

ISO 19880-2 applies to hydrogen dispensing systems (referred to as "dispensers") with dispensing pressures up to the H70 pressure class. It specifies requirements and test methods for the dispenser and associated functions required to deliver compressed hydrogen to a vehicle, and it identifies when specific component standards in the ISO 19880 series apply. The standard does not set the accuracy requirements for flow meters used to meter dispensed fuel.

Key topics and requirements

• Safety requirements for dispenser equipment and installations (mechanical, electrical and control safety).
• Test methods for verifying dispenser functionality and safety performance.
• Support for fuelling protocol implementation and requirements to interface with ISO 19880-1 station-level procedures.
• Coverage of dispenser configurations from fully contained cabinets to distributed component arrangements.
• Applicability up to H70 pressure class (high-pressure gaseous hydrogen dispensing).
• Cross-references to other parts of the ISO 19880 series for specific components (e.g., valves, hoses, etc.).
• Requirements for user and vehicle interfaces, sensors (pressure, temperature), control systems and hose/connector assemblies.

Typical use and users

Primary users include hydrogen fuelling-station designers and manufacturers, dispenser and hose suppliers, test and certification laboratories, station operators, vehicle OEMs integrating fuelling interfaces, and regulators establishing permitting and safety rules for public and private fuelling stations. The standard is used for design verification, type-testing and to support regulatory compliance and interoperability at hydrogen refuelling stations.

Related standards

ISO 19880-2 is part of the ISO 19880 series for gaseous hydrogen fuelling stations. Relevant related parts include ISO 19880-1 (General requirements for fuelling stations) and other component-specific parts such as ISO 19880-3 (valves) and ISO 19880-5 (dispenser hoses and hose assemblies). Users should consult ISO 19880-1 for station-level requirements and the component parts for detailed design and test requirements.
