ISO 19880-2:2025
Résumé
This document specifies safety requirements and test methods for the components and systems that enable the transfer of compressed hydrogen to a hydrogen vehicle, as addressed in ISO 19880-1, by a hydrogen dispenser with dispensing pressures up to the H70 pressure class designation.
This document applies to a hydrogen dispensing system, referred to as a “dispenser”; the configuration of the dispenser can range from:
a) a dispenser cabinet, located in the fuelling area, that can perform all of the functionality needed to deliver hydrogen to a vehicle, to
b) a minimum set of components mounted in or on (as applicable) a dispenser cabinet or other supporting structure as appropriate, with the remaining functionality provided elsewhere in the hydrogen fuelling station.
A dispensing system includes the user and vehicle interface and can include components starting from the hydrogen supply, such as a connection to the banking system, a cooling unit, a dispenser control system, a flow meter, a pressure sensor, a fuel temperature sensor, an ambient temperature sensor, user interface and a fuelling hose assembly. Not all dispensing system equipment has to be physically housed within the enclosure at the dispensing area, as long as the specification of component design or type and location are adequate to ensure that the overall process meets the requirements in this document.
This document specifies the requirements for hydrogen dispensers and can provide specific references to other standards for individual components included in the hydrogen dispenser, such as valves (ISO 19880-3) and hoses (ISO 19880-5).
This document specifies general requirements for supporting the fuelling protocol and directs the user to ISO 19880-1 for additional requirements and the test methods required to verify proper fuelling protocol implementation.
This document does not specify the accuracy of flow meters that can be used to meter dispensed fuel.
