Overview
EN 2047:2001 - Aerospace series - Beaded L‑section extruded, in aluminium alloys - Dimensions - is a CEN/AECMA European standard that specifies the dimensional characteristics and tolerances for beaded L‑section aluminium extrusions used in aerospace applications. Published in 2001 and implemented nationally by CEN members, EN 2047 is part of the EN metallic materials series organized under EN 4258.
Key search terms: EN 2047, beaded L‑section extruded, aluminium alloys, aerospace extrusions, dimensions and tolerances.
Key Topics
- Scope and form: Defines the form (beaded L‑section) for extruded aluminium alloy profiles intended for aerospace use.
- Recommended dimensions and masses: Provides recommended heights, widths, thicknesses and linear mass values (expressed in mm and kg/m) for a range of standard section sizes.
- Beaded radii: Specifies geometric details for bead radii on the L‑section (document indicates radii relationships such as R1 = S and R2 = S where S is the section parameter).
- Dimensional and geometric tolerances: References EN 2066 for general tolerances on extruded aluminium sections (linear dimensions, length and geometric tolerances).
- Normative organization: Placed within the aerospace metallic materials series; links to the general organization described in EN 4258 and uses EN 2066 for tolerancing rules.
Applications
EN 2047 is intended for use where consistent, interchangeable beaded L‑section aluminium extrusions are required in aerospace structures and assemblies. Typical users and applications include:
- Aerospace design engineers specifying structural and secondary metallic profiles.
- Extrusion manufacturers producing beaded L‑sections to meet aerospace dimensional requirements.
- Quality and inspection teams verifying conformance to dimensional tolerances and geometric requirements.
- Procurement and supply-chain teams who require standardized part definitions for sourcing and interchangeability.
- Certification and regulatory bodies referencing harmonized European standards for material/product conformity.
Practical uses:
- Window frames, fairings, trims, stiffeners and light structural elements where an L‑section with bead detail is specified.
- Standardized catalogue entries for suppliers to ensure compatibility across OEMs and tiered suppliers.
Related Standards
