General Information
Overview
EN 2258:1997 (adopted as SIST EN 2258:2001) is a CEN aerospace series standard that defines the dimensions and tolerances for circular tubes used for fluids made from aluminium and aluminium alloys. The standard covers tubes with diameters from 3.2 mm to 100 mm and wall thicknesses from 0.6 mm to 2.5 mm, intended specifically for use in aerospace fluid systems.
Key topics and requirements
- Scope and applicability
- Dimensional requirements for circular aluminium tubes used in aircraft and aerospace fluid lines.
- Applies to tubes with D = 3.2 mm … 100 mm and a = 0.6 mm … 2.5 mm.
- Materials
- Tubes manufactured from aluminium and aluminium alloys (material grades are referenced generically; consult material-specific standards for composition and mechanical properties).
- Dimensions and tolerances
- Specifies nominal diameters, wall thickness ranges, and the associated tolerances required for aerospace interchangeability and reliable installation.
- Standards identification
- European Norm reference: EN 2258:1997; national adoption example: SIST EN 2258:2001.
- Classification and indexing
- ICS fields: aluminium products (49.025.20) and aerospace fluid systems/components (49.080).
(Note: the standard text provides the dimensional/tolerance tables and precise limits; consult the full EN 2258 document for exact numeric tolerances and measurement procedures.)
Applications
- Design and engineering of aerospace fluid systems (hydraulic, pneumatic, fuel, lubrication, instrumentation tubing).
- OEMs and suppliers specifying aluminium tubing for airframe and engine fluid circuits.
- Procurement and quality control teams verifying tube compliance with aerospace dimensional requirements.
- Maintenance, repair and overhaul (MRO) operations replacing or repairing fluid lines to prescribed dimensions and tolerances.
- Useful in regulatory compliance and certification processes where consistent tube dimensions are required for system integrity.
Who uses this standard
- Aircraft manufacturers, aerospace suppliers, tubing manufacturers, aerospace design engineers, procurement engineers, inspection and quality assurance personnel, and certification authorities.
Related standards
- EN 2258 is part of the aerospace series and commonly referenced alongside material standards for aluminium alloys, fittings and couplings standards, and fluid system installation standards. Consult national adoptions (e.g., SIST EN 2258:2001) and other CEN/ISO standards for complementary requirements.
