Full title and description
St ISO 7314-2002 — Aerospace — Fluid systems — Metal hose assemblies. This International Standard specifies requirements for medium‑pressure, high‑temperature flexible metal hose assemblies intended for aerospace pneumatic and fluid systems, including construction types, performance limits and intended applications.
Abstract
ISO 7314:2002 gives specifications for medium‑pressure, high‑temperature flexible metal hose assemblies suitable for continuous operation in liquid and pneumatic systems from −55 °C to +400 °C, with short‑duration excursions up to +650 °C. The assemblies are intended for aerospace use (pneumatic systems, bleed air, heating/ventilating and instrument air systems). Two hose assembly types are defined (convoluted inner tube — welded; and convoluted inner tube — seamless or butt‑welded and redrawn). The standard also notes limitations such as flow velocity not exceeding 54 m/s unless special vibration‑damping devices are used.

Scope
Specifies the construction, performance and application limits for flexible metal hose assemblies used in aerospace fluid and pneumatic systems. Covers two types of convoluted metal inner‑tube hose assemblies suitable for conveying air and other gases in aircraft pneumatic systems, bleed air systems, heating and ventilating systems and instrument air systems; defines temperature and short‑duration excursion limits and notes velocity and vibration considerations.
Key topics and requirements
- Temperature range and short‑duration excursions (continuous −55 °C to +400 °C; short excursions up to +650 °C).
- Definition of two hose assembly types: Type 1 — convoluted inner tube (welded), moderate mass/flexibility; Type 2 — convoluted inner tube (seamless or butt‑welded and redrawn), low mass/high flexibility.
- Intended applications in aerospace pneumatic and fluid systems (bleed air, instrument air, HVAC).
- Performance and safety limits, including flow velocity guidance (not covering assemblies with flow velocity exceeding 54 m/s without special damping).
- Requirements for construction, marking/identification and conformity to specified performance criteria (pressure/temperature endurance, flexibility and leak performance as applicable to hose assemblies).
Typical use and users
Used by aerospace OEMs, component and hose‑assembly manufacturers, design and certification engineers, maintenance/repair organizations (MROs), procurement/specification teams and regulatory/certification bodies involved in aircraft fluid and pneumatic system design and maintenance. Engineers use it to specify compatible hose assemblies, verify supplier conformance and support qualification of hose assemblies for aircraft installations.
