Описание (английский):

This document specifies design, construction, type and production testing, and marking requirements for both non-insulated cryogenic flexible hoses and insulated vacuum jacketed hoses used for the transfer of cryogenic fluids within the following range of operating conditions: — working temperature range: from −270 °C to +65 °C; — nominal size (DN): from 10 to 100. End fittings for mounting of any couplings are within the scope of this document, but the couplings are subject to other standards.

Overview

EN ISO 21012:2024 (ISO 21012:2024) is the international/CEN standard for cryogenic hoses used to transfer cryogenic fluids. It covers both non‑insulated flexible hoses and insulated vacuum‑jacketed hoses within a working temperature range of −270 °C to +65 °C and nominal sizes DN 10 to 100. The standard specifies requirements for design, materials, construction, type and production testing, marking, cleaning and documentation. End fittings for couplings are included, while the couplings themselves are addressed by other standards.

Key topics and technical requirements

Scope and hose types: Non‑insulated flexible hoses and vacuum‑jacketed (insulated) hoses for cryogenic service.

Operating limits: Temperature range −270 °C to +65 °C; nominal sizes DN 10–100.

Design & construction: General requirements for hose assemblies, including end fittings and material selection.

Materials & cleanliness: Material suitability for cryogenic temperatures and requirements for internal cleanliness for safe transfer of cryogens.

Mechanical properties & tests:

Burst pressure and hydraulic bursting tests.
Pressure cycling and fatigue/resistance to repeated pressure changes.
Bending and rolling‑bend cycling tests for flexural durability (separate procedures for common and non‑common materials).
Leak tightness and crushing resistance checks.
Low temperature resistance and resistance to abuse.

Sampling, production and non‑destructive tests: Requirements for sample testing, dimensional checks, leak tests and production testing.

Marking, cleaning and documentation: Mandatory marking elements, cleaning procedures for cryogenic service, periodic examination guidance and test certificates.

Regulatory linkage: Annex ZA relates the standard to the EU Pressure Equipment Directive (2014/68/EU), providing a route to presumption of conformity when applicable.

Applications and users

Manufacturers and designers of cryogenic hose assemblies (flexible and vacuum‑jacketed).

Quality assurance and testing laboratories performing type and production tests.

Plant operators and maintenance teams in industries handling cryogens (industrial gases, LNG, hydrogen applications, laboratories and medical gas supply).

Specifiers and procurement teams seeking compliant hoses for transfer lines, loading/unloading, and interconnects between cryogenic vessels.

By following EN ISO 21012:2024, stakeholders ensure safer, more reliable cryogenic fluid transfer and clearer conformity with applicable pressure equipment regulations.
