ISO 19880-5:2025

Overview - ISO 19880-5:2025 (Gaseous hydrogen - Fuelling stations - Part 5)

ISO 19880-5:2025 specifies safety, material, design, manufacture and testing requirements for dispenser hoses and hose assemblies used to dispense gaseous hydrogen at fuelling stations. It targets wire- or textile-reinforced flexible hoses suitable for high-pressure hydrogen up to 70 MPa nominal working pressure and for an operating temperature range of −40 °C to 65 °C. The standard focuses on hose performance and safety for hydrogen refuelling from dispensers to vehicles; it explicitly excludes vehicle on‑board high‑pressure systems, vehicle low‑pressure delivery systems, and flexible metal hoses.

Key topics and technical requirements

The standard organizes requirements across materials, construction, testing and documentation. Key technical topics include:

• Materials and construction: lining, reinforcement (wire or textile), outer cover and requirements for static‑dissipation on internal and external surfaces.
• Dimensions and tolerances: specification of acceptable hose sizes and tolerances for interchangeability.
• Performance requirements and tests, including:
  • Leakage tests (type and routine)
  • Hydrostatic strength (proof and ultimate strength)
  • Electrical conductivity and static dissipation testing
  • Tensile, vertical load and torsion strength tests
  • Pressure-cycle (hydraulic impulse) tests and hydrogen impulse tests (Annex C)
  • Corrosion, ozone, UV/water exposure, crush, abrasion and permeation tests
  • Minimum bend radius and marking material legibility
• Marking and documentation: marking of hoses, end fittings and assemblies plus required instruction manuals and test reports to support selection, installation, inspection and maintenance.

Practical applications and who uses ISO 19880-5

This standard is essential for stakeholders involved in hydrogen fuelling station design, procurement and operation:

• Hose and hose-assembly manufacturers: to design, verify and certify products for hydrogen dispensing up to 70 MPa.
• Fuel dispenser OEMs and station integrators: to ensure hose compatibility and safe dispenser interfaces.
• Test laboratories and certification bodies: to perform specified type and routine tests and produce compliant test reports.
• Station operators, maintenance and safety engineers: for guidance on selection, installation, inspection, maintenance and safety precautions.
• Regulators and code officials: to reference consistent requirements for hydrogen infrastructure safety and performance.
