Overview

EN 6025:2021 - "Aerospace series - Plates - Aluminium alloy 2024 - Close tolerances flatness - Thickness 6 mm < a ≤ 55 mm - Dimensions" - is a European (CEN) standard that specifies the dimensional sizes and tolerances for aluminium 2024 plates intended for aerospace use. It covers plate form, recommended formats and mass per unit area, dimensional and geometric tolerances, material delivery condition and designation rules for plates with thicknesses greater than 6 mm up to 55 mm.

Key Topics and Requirements

• Scope: Plates in aluminium alloy 2024 with close-tolerance flatness, thickness 6 mm < a ≤ 55 mm.
• Form and dimensions: Figure and nominal size codes with recommended normal formats and mass per unit area (mass calculations use density 2.8 kg/dm³).
• Dimensional tolerances:
  • Thickness tolerances by thickness band and plate width (detailed tabulation).
  • Width tolerance: +10 / 0 mm for all widths.
  • Length tolerance: +10 / 0 mm for l ≤ 5 000 mm; proportional tolerance for longer lengths.
• Geometric tolerances (measurement methods according to EN 3848):
  • Squareness (diagonal difference limits).
  • Lateral curvature (concave/convex limits).
  • Flatness (separate values by thickness ranges and chord/length/width conditions; note excludes conditions O and F).
• Material and delivery condition: Material specified per EN 6000 (AL‑P2024‑T351) - delivery condition T351 A.
• Designation and ordering: Grain flow default parallel to long edge; use abbreviation FAS when grain flow is required parallel to the short edge.
• Referenced technical spec: EN 6071 for aluminium/aluminium alloy wrought product technical specification.

Practical Applications and Users

This standard is intended for professionals involved with aerospace metallic semi-finished products:

• Aircraft OEMs and Tier suppliers specifying plate material for structural components.
• Materials and procurement engineers creating purchase specifications.
• Quality assurance and inspection teams measuring flatness, squareness and dimensional compliance (using EN 3848 measurement methods).
• Fabricators and machinists who require known tolerances for downstream manufacturing and machining allowances.

Using EN 6025:2021 helps ensure compatibility between suppliers and aerospace manufacturers, reduce rework from out-of-tolerance plates, and support consistent structural performance where aluminium 2024 plates are used.
