Overview
EN 6054:2025 is a European standard developed by CEN, specifying the characteristics of swage locking, shear type collars made from aluminium alloy 6061-T7, complete with conversion coating. These collars are designed for use in aerospace applications that require reliable shear strength and fastening integrity. The standard defines collars suitable for a maximum operating temperature of 80°C and follows the inch series dimensioning system.
This standard is typically used in tandem with other aerospace fastener standards, such as EN 6050, EN 6100, and EN 6120, ensuring compatibility within critical aerospace assemblies.
Key Topics
Collar Characteristics: The collars specified in EN 6054:2025 are swage locking, shear type, constructed from aluminium alloy 6061-T7. They are treated with a conversion coating for corrosion resistance, ensuring long-term durability in demanding environments.
Dimensions and Tolerances: EN 6054 details precise configurations, including dimensions and tolerances, to guarantee interchangeability and consistent performance across aerospace hardware.
Surface Treatment: The standard requires a chemical conversion coating in accordance with recognized aerospace specifications, supporting resistance to corrosion and environmental factors.
Quality and Marking: Requirements for product marking and traceability are included, along with guidelines for manufacturer quality management systems in line with established aerospace sector norms.
Integration: This standard is designed for use with pins specified in EN 6050, EN 6100, or EN 6120, reinforcing a system-based approach to aerospace fastening solutions.
Applications
EN 6054:2025 is highly relevant for the following use cases across aerospace manufacturing and maintenance:
Aircraft Structural Assembly: These shear type collars are used in conjunction with compatible pins to create strong, vibration-resistant joints in the airframe and other critical structures.
Aerospace Fastener Systems: Their design ensures compatibility with standardized aerospace pins, enabling system-level integration and streamlined assembly processes.
Maintenance and Repair Operations (MRO): Standardized collars facilitate consistent part replacement, inspections, and traceability, supporting aircraft reliability and safety.
Quality Assurance: The mandate for manufacturers to adhere to a recognized aerospace quality management standard (such as EN 9100) assures high production consistency and traceability.
Conversion Coating Benefits: Improved environmental resistance makes these collars suitable for various aerospace environments where corrosion prevention is essential.
