scope:

This standard provides the safety requirements and test methods for complete compressed hydrogen dispensers with dispensing pressures up to the H70 pressure class designation. A typical hydrogen dispenser is illustrated in Figure 1 as installed and fueling a vehicle.

The process diagram in Figure 2 shows components in the dispenser typically required to meet the dispensing functionality and safety requirements. The actual process configuration and equipment selections may be different, but ultimately the requirements defined by this document need to be met by the dispensing system. Additionally, not all 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 standard.

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 19880-3).

This document addresses the general requirements of the fueling protocol and directs the user to ISO 19880-1 for additional requirements and the test methods required to verify proper fueling protocol implementation.

This document does not address the accuracy of flow meters that may be used to meter dispensed fuel.
