Gaseous hydrogen – Fuelling stations Part 5: Dispenser hoses and hose assemblies

Standard specifies the requirements for wire- or textile-reinforced hoses and hose assemblies suitable for dispensing hydrogen up to 70 MPa nominal working pressure in the operating temperature range of −40°C to 65°C. It also sets out safety requirements for material, design, manufacture, and testing of gaseous hydrogen hose and hose assemblies for hydrogen fuelling stations.
Hoses and hose assemblies excluded from the scope of this standard are:
(a) Those used as part of a vehicle high-pressure on-board fuel storage system;
(b) Those used as part of a vehicle low-pressure fuel delivery system; and
(c) Flexible metal hoses.
NOTE –
(1) This document was developed primarily for hoses and hose assemblies for dispensing high-pressure hydrogen from refuelling dispensers to hydrogen vehicles. Requirements for hoses used to deliver hydrogen from a transportable vessel (for example, a trailer) into a station’s buffer storage are addressed in ISO 16964:2019, Gas cylinders − Flexible hoses assemblies − Specification and testing.
(2) Hose assemblies include the hose with connectors on each end (see Figure 1). Each connector has two basic functional elements that are addressed as described below:
(a) Coupling to hose: This function is defined by requirements and verified (along with the hose itself) by performance-based tests in this document.
(b) Fitting for transition and connection to the piping system or equipment: This function is addressed by reference to appropriate hydrogen equipment standards and piping codes.
The standard was prepared by the P3652 Hydrogen Standards Committee and is identical to and has been reproduced from ISO 19880-5:2019, Gaseous hydrogen – Fuelling stations – Part 5: Dispenser hoses and hose assemblies.
