EN 2617:2001

Overview

EN 2617:2001 is a European standard developed by CEN specifying the dimensions and tolerances for plates made from titanium and titanium alloys used in aerospace applications. It applies to plates with a thickness range from 6 mm up to 100 mm, ensuring standardized manufacturing quality and dimensional accuracy in aerospace component fabrication. This standard supports consistent quality control, facilitates international trade, and ensures compatibility across aerospace manufacturing processes involving titanium materials.

Key Topics

• Material Specification
  Focuses on titanium and titanium alloys, widely recognized for their high strength-to-weight ratio, corrosion resistance, and performance under extreme aerospace operating conditions.

• Thickness Range
  Covers titanium plates with thicknesses between 6 mm and 100 mm, a commonly used range for structural aerospace parts.

• Dimensional Tolerances
  Defines permissible deviations for:

  • Thickness (measurements taken 10 mm to 75 mm from the plate edge)
  • Width and length tolerances to ensure the plates fit precise aerospace assembly requirements.

• Geometric Tolerances
  Establishes standards for:

  • Squareness of plates - maximum diagonal length differences to control angular deviations.
  • Lateral curvature - limits on concave or convex bending to maintain flatness.
  • Flatness - maximum allowable deviations across the surface to maintain uniform sealing and fitting in aircraft components.

• Measurement Methods
  References EN 3848 for standardized measurement procedures of geometric form deviations, ensuring reproducibility and reliability of dimensional assessments.

Applications

EN 2617:2001 plays a crucial role in aerospace manufacturing by standardizing titanium plate dimensions, impacting:

• Aircraft Structural Components
  Titanium plates produced according to this standard are used in fuselage, wing, and engine parts requiring lightweight yet durable materials capable of withstanding stress and fatigue.

• Aerospace Engine Parts
  High-performance titanium alloy plates meet stringent dimensional requirements for turbine blades, compressor discs, and other engine components.

• Spacecraft Manufacturing
  Precise dimensional control of titanium plates is critical in constructing satellites and launch vehicles where material performance and weight savings are vital.

• Quality Assurance and Compliance
  Aerospace suppliers and manufacturers utilize this standard to verify product conformity, facilitate certification processes, and maintain traceability and compliance with European aerospace quality regulations.
