Full title and description

STB UNE-EN ISO 16964-2020 — Gas cylinders. Flexible hoses assemblies. Specification and testing. This designation refers to the EN ISO 16964:2020 adoption of ISO 16964:2019 and is published nationally as UNE-EN ISO 16964:2020 (Spanish national edition). It specifies requirements and type/tests for high‑pressure flexible hose assemblies intended to be connected to gas cylinders, bundles or trailers and MEGCs for filling and emptying operations at production sites and for customer use.

Abstract

This standard provides specification and testing requirements for high‑pressure flexible hose assemblies with rated pressures up to 1 000 bar for use in the temperature range −40 °C to +65 °C. It describes type testing, burst and leak tests, compatibility and material considerations and lists exclusions (for example welding/cutting hoses, medical gas hoses, cryogenic hoses and LPG hoses). The EN/UNE adoption is identical in technical content to ISO 16964:2019 / EN ISO 16964:2020.

Scope

Applies to high‑pressure flexible hose assemblies intended for connection to gas cylinders, cylinder bundles or trailers (battery vehicles) and multiple‑element gas containers (MEGCs) used when filling and emptying gas at production sites and for customer use. The standard covers assemblies with rated pressures up to 1 000 bar and the temperature range −40 °C to +65 °C. It excludes: rubber/plastic hoses for welding/cutting, hoses for medical gas systems, low‑pressure medical gas hoses, cryogenic hoses and LPG flexible hose assemblies — these are covered by other specific standards.

Key topics and requirements

• Definitions and terminology relevant to flexible hose assemblies for gas cylinders.
• Design and material requirements to ensure pressure containment and compatibility with gases handled (including oxygen and specialty gases).
• Rated pressure classes up to 1 000 bar and temperature range requirements (−40 °C to +65 °C).
• Type tests: burst testing, leak testing, endurance (cyclic) tests and type‑approval procedures.
• Additional tests: bend, impact, tension and torsion tests as appropriate for hose assembly design and intended use.
• Marking, documentation and traceability requirements for hose assemblies and fittings.
• Exclusions and cross‑references to related standards for welding/cutting, medical gases, cryogenic and LPG applications.

Typical use and users

Used by manufacturers of high‑pressure hose assemblies, component suppliers (hoses, fittings, couplings), test laboratories, gas producers and distributors, filling station designers, quality and compliance engineers, and procurement/specification teams who need to ensure safe connection and transfer of gases between cylinders, bundles, trailers and MEGCs at production or customer sites. Also referenced by certification bodies and inspectors assessing conformity to EN/ISO requirements.

Related standards

Standards referenced or frequently used alongside ISO 16964 include (non‑exhaustive): ISO 14113 (welding/cutting hose assemblies), ISO 21969 (medical gas hose assemblies), ISO 5359 (low‑pressure medical gas hoses), ISO 3821 / ISO 12170 (welding/cutting low‑pressure hoses), ISO 21012 (cryogenic hose assemblies), and the EN ISO series equivalents where applicable. The European adoption EN ISO 16964:2020 is technically identical to ISO 16964:2019.

FAQ

Q: What is this standard?

A: It is the national adoption (UNE-EN ISO 16964:2020) of ISO 16964:2019 — an international standard specifying requirements and tests for high‑pressure flexible hose assemblies used with gas cylinders, bundles, trailers and MEGCs.

Q: What does it cover?

A: Specification and testing (type tests and routine considerations) for flexible hose assemblies with rated pressures up to 1 000 bar for use between −40 °C and +65 °C, including burst, leak and mechanical tests and marking/documentation rules; it explicitly excludes certain hose types covered by other ISO standards.

Q: Who typically uses it?

A: Manufacturers, test laboratories, gas producers/distributors, safety and compliance engineers, procurement/specification teams, and certification/inspection bodies engaged with gas cylinder filling and transfer equipment.

Q: Is it current or superseded?

A: The ISO edition is ISO 16964:2019 (2nd edition). The EN/UNE adoption EN ISO 16964:2020 / UNE‑EN ISO 16964:2020 is the current national adoption; the ISO record indicates the standard is published and reviewed on a regular cycle. Check the national publisher (AENOR/UNE) or ISO for any amendments or later revisions before use.

Q: Is it part of a series?

A: It is part of the family of standards addressing hoses, hose assemblies and gas cylinder equipment; related ISO standards cover welding/cutting hoses, medical gas hoses, cryogenic hoses and others (see Related standards above).

Q: What are the key keywords?

A: Gas cylinders; flexible hoses; hose assemblies; pressure testing; burst/leak tests; type testing; fittings; MEGC; EN ISO 16964:2020; UNE.
