ISO 8913-2006 PDF

Full title and description

ISO 8913:2006 — Aerospace — Lightweight polytetrafluoroethylene (PTFE) hose assemblies, classification 400 °F / 3 000 psi (204 °C / 20 684 kPa) and 204 °C / 21 000 kPa (400 °F / 3 046 psi) — Procurement specification. This international standard specifies procurement, classification and performance requirements for lightweight PTFE hose assemblies intended primarily for aircraft hydraulic systems and, where acceptable, for certain pneumatic applications.

Abstract

ISO 8913:2006 sets out requirements for lightweight PTFE-lined hose assemblies used in aircraft hydraulic systems at temperatures between −55 °C and 204 °C (−65 °F and 400 °F) and at nominal pressures up to the classification limits given. It covers construction, pressure–temperature classification, tests, marking and procurement information, and notes limitations for use (for example high‑pressure pneumatic storage and oxygen service require purchaser approval).

Scope

The standard applies to lightweight PTFE hose assemblies designed for aircraft hydraulic systems and, where diffusion through the PTFE liner is acceptable, to certain pneumatic systems. It specifies temperature and pressure classifications (covering operation down to −55 °C and up to 204 °C and the named pressure classes), testing and procurement requirements, and includes guidance on limitations of use (e.g., high‑pressure pneumatic storage and oxygen service are excluded unless specifically approved by the purchaser).

Key topics and requirements

• Temperature range: −55 °C to 204 °C (−65 °F to 400 °F).
• Pressure classification: nominal pressure limits and two classification references covering approximately 3 000 psi (≈20 684 kPa) and 21 000 kPa (≈3 046 psi) as specified in the standard.
• Construction and materials: PTFE liner with specified reinforcement and outer coverings for lightweight aerospace applications.
• Required tests: pressure, burst, proof, leak and other performance tests defined for procurement acceptance.
• Marking, documentation and procurement clauses: identification, traceability and purchaser requirements for acceptance of assemblies.
• Limitations and special applications: notes on unsuitability for high‑pressure pneumatic storage and oxygen service without purchaser approval.

Typical use and users

Primary users are aerospace OEMs, aircraft component manufacturers, hose assembly suppliers, procurement and quality engineers, maintenance organizations and regulatory/certification bodies involved in aircraft hydraulic and selected pneumatic systems. The standard is used when specifying or procuring lightweight PTFE hose assemblies for airframe hydraulic installations and associated maintenance replacement items.

Related standards

ISO 8913:2006 is part of a family of procurement/test specifications for aerospace hose assemblies. The standard was previously published (ISO 8913:1994) and a draft revision (ISO/DIS 8913) has been indicated as under development to replace the 2006 edition. Users should also consider applicable national adoption documents or complementary aerospace hose specifications and procurement standards when preparing procurement requirements.

FAQ

Q: What is this standard?

A: ISO 8913:2006 is an ISO international standard that defines procurement and performance requirements for lightweight PTFE-lined hose assemblies used principally in aircraft hydraulic systems.

Q: What does it cover?

A: It covers construction, classification by temperature and pressure, required tests, marking, documentation and procurement information for lightweight PTFE hose assemblies, and notes limitations for certain uses (such as high‑pressure pneumatic storage and oxygen service without purchaser approval).

Q: Who typically uses it?

A: Aerospace OEMs, hose assembly manufacturers and suppliers, procurement and quality engineers, maintenance and repair organizations, and certification authorities involved with aircraft hydraulic (and selected pneumatic) systems.

Q: Is it current or superseded?

A: The 2006 edition is published and was reviewed and confirmed as current in 2024. A draft revision (ISO/DIS 8913) has been indicated as under development and is expected eventually to replace the 2006 edition; users should monitor the ISO catalogue or national standards bodies for any formal replacement or amendment.

Q: Is it part of a series?

A: It is part of ISO aerospace procurement/specification work for hose assemblies; editions and related procurement standards (and national adoptions) exist that address different hose constructions, pressure classes or reinforcement types. The ISO catalogue lists the standard’s lifecycle and related draft work such as ISO/DIS 8913.
