Overview
EN 6104:2026 is a comprehensive European standard developed by CEN, specifically addressing solid rivets and slugs made from aluminium or aluminium alloys for aerospace applications, following the inch series. This technical specification details the essential characteristics, manufacturing requirements, and quality assurance processes for rivets used in demanding aerospace environments. It covers key aluminium alloys, including 1050A-H14, 2017A-T42, 2117-T42, 5056A-H32, and 7050-T73, ensuring reliability and performance in aircraft assembly and related aerospace structures.
Key Topics
- Material Requirements: Specifies the aluminium and aluminium alloy grades acceptable for solid rivet production, ensuring optimal strength, durability, and corrosion resistance.
- Dimensions and Tolerances: Defines exact dimensional standards and tolerance levels for rivets and slugs, using highly accurate measurement techniques to meet critical aerospace requirements.
- Manufacturing Processes: Outlines processes such as heat treatment (according to SAE AMS2770) and surface treatment for achieving consistent mechanical properties and surface quality.
- Quality Assurance: Sets criteria for manufacturer approval (e.g., EN 9100 compliance), batch approval processes, and inspections, including statistical sampling in accordance with ISO 2859-1.
- Testing Methods: Requires mechanical tests (shear strength, driveability), visual inspections (to detect surface discontinuities or defects), and metallurgical evaluations (grain size, microstructural integrity).
- Certification and Documentation: Mandates detailed documentation and certificates of compliance to accompany each shipment, providing traceable records of conformance.
- Packaging and Labelling: Establishes best practices for contamination-free packaging, proper marking, and labelling to preserve quality during transportation and storage.
Applications
Solid aluminium and aluminium alloy rivets standardized under EN 6104:2026 are crucial in a wide range of aerospace manufacturing and maintenance functions, including:
- Aircraft Assembly: Ensuring robust and lightweight fastening of structural components such as fuselage panels, wings, and internal substructures.
- Aerospace Equipment Manufacturing: Used in satellites, spacecraft, and related aerospace technology, where precision and reliability are paramount.
- Repair and Maintenance: Providing compatible and standardized components for on-site repair or retrofit operations on existing airframes or aerospace systems.
- High-Reliability Sectors: Applicable in other high-performance or security-critical environments where the combination of lightweight design and mechanical strength is essential.
By addressing stringent aerospace industry demands, EN 6104:2026 ensures rivets provide long service life, resistance to adverse conditions, and compatibility with advanced assembly processes.
