Overview

EN 6054:2025 is a European standard developed by CEN specifying requirements for aerospace collars-specifically, swage locking, shear-type collars made from aluminium alloy 6061-T7 with conversion coating, conforming to the inch series. Designed for aerospace applications, these collars operate reliably at temperatures up to 80 °C. The standard is intended for use in conjunction with related standards EN 6050, EN 6100, and EN 6120, which cover compatible pin types.

This standard ensures uniformity in collar characteristics including configuration, dimensions, material properties, surface treatment, and quality management, promoting safety, reliability, and interchangeability in aerospace fastener assemblies.

Keywords: Aerospace collars, swage locking, shear type, aluminium alloy 6061-T7, conversion coating, inch series, aerospace fasteners, EN 6054.

Key Topics

  • Material and Surface Treatment:
    Collars must be manufactured from aluminium alloy 6061-T7 with heat treatment and conversion coating per MIL-DTL-5541F (gold chromate with green dye). Lubrication uses cetyl alcohol in compliance with AS87132 to ensure minimal friction and corrosion resistance.

  • Configuration and Dimensions:
    Detailed specifications define collar shape, dimensions, tolerances, and mass to ensure precise fit and function. Dimensions are given in millimeters and must meet strict dimensional tolerances before lubrication.

  • Compatibility:
    EN 6054 collars are designed to be used with pins specified in EN 6050, EN 6100, or EN 6120, facilitating standardized assembly of aerospace fastener systems.

  • Marking and Identification:
    Marking requirements follow EN 2424, style F, with depressed markings up to 0.25 mm in depth, allowing traceability without compromising structural integrity.

  • Quality Management:
    Manufacturers must implement an aerospace-approved Quality Management System such as EN 9100 or equivalent. Qualification follows procedures like EN 9133 to verify compliance with design and performance requirements.

Applications

EN 6054 collars are critical components in aerospace engineering, used primarily for fastening applications that demand high shear strength, reliability, and resistance to environmental factors. Common applications include:

  • Aircraft structural assemblies where swage locking collars secure pins against shear forces
  • Aerospace hardware requiring lightweight yet durable fasteners with corrosion protection
  • Systems operating within a maximum temperature of 80 °C, ensuring stable mechanical properties under typical flight conditions
  • Assemblies involving pins compatible with EN 6050, EN 6100, or EN 6120 for modular and repairable connections

Implementing this standard supports enhanced safety and efficiency in aerospace manufacturing, maintenance, and repair operations, improving lifecycle performance of aerospace components.

  • EN 6100: Aerospace pins with 100° countersunk head, shear type, aluminium alloy 7050
  • EN 6120: Aerospace pins, protruding head, shear type, aluminium alloy 7050
  • EN 2424: Marking of aerospace products ensuring consistent product identification
  • EN 9100: Quality management system requirements for aviation, space, and defence industry
  • EN 9133: Qualification procedures for aerospace standard products
  • MIL-DTL-5541F: Chemical conversion coatings on aluminium and its alloys for corrosion resistance
  • AS87132: Lubricant specifications for aerospace fasteners

Compliance with EN 6054 alongside these standards guarantees a comprehensive, regulated approach to aerospace fastening solutions, facilitating interoperability and high performance across the aerospace sector.
