EN 2071:2001 - Aerospace series - Sheets in aluminium and aluminium alloys - Thickness 0,25 mm < a < 6 mm - Dimensions

Overview

EN 2071:2001 is a CEN/AECMA aerospace series standard that specifies dimensions and tolerances for aluminium and aluminium-alloy sheets used in aerospace applications. It applies to flat sheets with a thickness range 0.25 mm < a < 6 mm, and defines recommended formats, mass per unit area, dimensional limits and geometric tolerances to ensure consistent material supply and inspection criteria across the aerospace supply chain.

Key topics and technical requirements

  • Scope: Covers sheets in aluminium and aluminium alloys for aerospace use, thickness from 0.25 mm up to 6.0 mm.
  • Recommended formats and mass: The standard includes typical widths and lengths (formats) and gives mass per unit area values (calculated using a reference density of 2.8 kg/dm3) to aid specification and procurement.
  • Dimensional tolerances: Detailed tables specify tolerances for:
    • Thickness - tolerances depend on nominal thickness and sheet width; measurements are taken at least 12 mm from the edge.
    • Width and length - tolerances vary by thickness band and specified sheet length.
  • Geometric tolerances: Defines acceptable limits for:
    • Squareness (method per EN 3848) - maximum diagonal differences are tabulated by sheet length.
    • Lateral curvature - may be concave or convex; measurement and limits are provided.
    • Flatness - specified except when the sheet is in the annealed condition (flatness not applicable to annealed sheets).
  • Measurement methods and references: The standard references EN 3848 for measuring form deviations and EN 4258 for the organization of aerospace metallic-material standards.

Practical applications and users

EN 2071 is used to:

  • Create unambiguous material specifications in purchase orders and technical drawings for aerospace structures and components.
  • Define acceptance criteria for incoming material inspection and quality control in manufacturing.
  • Guide sheet-stock selection (format, thickness, flatness) for forming, machining and assembly operations.
  • Support certification and supplier qualification by providing harmonized dimensional requirements.

Typical users:

  • Aerospace OEMs and tier suppliers
  • Material and sheet stock manufacturers
  • Quality and inspection engineers
  • Procurement and specification writers
  • Test laboratories and certification bodies

Related standards

  • EN 3848 - Method of measuring form deviations (referenced for squareness, flatness and curvature measurements)
  • EN 4258 - Organization of aerospace metallic-material standards and linking of EN standard types

EN 2071:2001 helps ensure consistent quality and interchangeability of aluminium sheet stock in aerospace contexts by standardizing dimensions, tolerances and measurement practices.
