This document describes the 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 is intended to cover a hydrogen dispensing system, referred to as a "dispenser", the configuration of which can range from i) a dispenser cabinet, located in the fuelling area, that can perform all of the functionality needed to deliver hydrogen to a vehicle, to ii) 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 may 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, fuel 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 requirements in this document.

This document provides the requirements for hydrogen dispensers and may 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 addresses the 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 address the accuracy of flow meters that may be used to meter dispensed fuel.
