EN 2050:2001

Overview

EN 2050:2001 is a European standard established by the Comité Européen de Normalisation (CEN) that defines the dimensions and tolerances for extruded T-sections made from aluminium alloys, specifically designed for aerospace applications. This standard is part of a wider aerospace series focusing on metallic materials, ensuring consistent quality and interoperability within the aerospace industry.

The document was prepared under the guidance of the European Association of Aerospace Manufacturers (AECMA) and directed at all national standardization bodies within the CEN member countries. EN 2050:2001 establishes clear specifications for height, width, thickness, linear mass, and dimensional tolerances, thus supporting manufacturers and engineers involved in the design and production of aluminium aerospace components.

Key Topics

• Scope and Application
  The standard applies exclusively to extruded T-sections in aluminium alloys used in aerospace. It covers all necessary physical dimensions and limits deviations through defined tolerances to maintain the reliability and performance needed in aerospace engineering.

• Dimensional Specifications
  Dimensions such as height, base width, thickness, and linear mass per meter are clearly detailed. Table 1 within the standard provides comprehensive permissible values, enabling consistent production quality.

• Tolerances and Quality Control
  EN 2050 references EN 2066, which provides general tolerances for extruded aluminium sections, ensuring compatibility and interchangeability in aerospace assemblies. Geometric and length tolerances are also governed under EN 2066 to maintain high precision.

• Beaded Radii
  The standard defines recommended radii (R1 and R2) for the T-section beads to optimize structural performance and stress distribution.

• Compliance and Standardization
  To harmonize aerospace manufacturing across Europe, EN 2050:2001 requires adoption as a national standard by all CEN member countries, ensuring a unified approach to aluminium T-section production.

Applications

• Aerospace Structural Components
  EN 2050:2001 extruded aluminium T-sections are ideal for constructing lightweight yet strong frameworks, internal supports, and load-bearing elements in aircraft and spacecraft.

• Aerospace Manufacturing and Assembly
  The standardized dimensions allow manufacturers to fabricate parts that fit precisely, reducing production errors and assembly time within aerospace supply chains.

• Material Engineering and Testing
  Materials engineers benefit from this standard by having fixed criteria for design validations, stress testing, and compliance verification.

• Aerospace Repair and Maintenance
  Maintenance and repair services use these standardized sections to replace components accurately, preserving the integrity and safety of aerospace vehicles.
