Overview
EN 4691-2:2018 is a European Standard developed by the Comité Européen de Normalisation (CEN) specifically for the aerospace industry. It focuses on a construction kit of tie rod assemblies equipped with integrated bolts, designed for aerospace applications. These tie rods feature two adjustable ends with integrated bolts and are suitable for interior and sub-structural use. The standard mandates performance suitability within a temperature range from −55 °C to 85 °C, ensuring reliability in diverse aerospace environments.
The standard was approved by CEN in 2016 and is applicable across various European countries, promoting harmonization in aerospace component manufacturing. As part of the Aerospace and Defence Industries Association of Europe (ASD-STAN) standards, EN 4691-2 aligns with stringent aerospace design and safety requirements.
Key Topics
Scope and Application: The document specifies the design and modular construction kit of rod assemblies with two adjustable ends integrated with bolts. These components are essential for sub-structure and interior aerospace use, covering applications that must endure extreme cold and warm temperatures (-55 °C to 85 °C).
Assembly Codes:
- EN 4693: Assembly codes A, B, and C – tailored for lower tension and compression loads, rod diameter 20 mm.
- EN 4694: Assembly codes D, E, and F – suitable for higher tension and compression loads, rod diameter 25.4 mm.
- EN 4695: Assembly codes G, H, and K – designed for lower loads but with shorter rod lengths, also with 20 mm diameter.
Locking Clips (EN 4692): Locking clips secure the tie rods after length adjustment, ensuring the assemblies maintain structural integrity under load. Different size codes are defined for various assembly needs (e.g., size code 01, 02, 03R, etc.).
Standard Evolution: The latest edition of EN 4691-2 includes updated references to patent rights and the removal or reclassification of related clauses or standards to reflect current technological and regulatory developments.
Applications
EN 4691-2:2018 components are utilized in aerospace sub-structures and interior assemblies where precision, adjustability, and reliability under extreme temperature fluctuations are critical. Tie rods and integrated bolts compliant with this standard can be found in:
- Aircraft fuselage interior frameworks
- Aerospace sub-structural assembly points requiring tension and compression resistance
- Mechanical linkages where tie rods with adjustable ends provide load management and vibration control
- Environments demanding components that withstand harsh temperature cycles without failure
The modular construction kit approach facilitates efficient assembly, maintenance, and replacement of parts in aerospace manufacturing and service environments, enhancing operational efficiency and safety.
Related Standards
EN 4691-2:2018 references and complements a range of aerospace series standards concerning tie rods and related components, including:
- EN 4692: Tie rods with integrated bolts – Locking clip specifications necessary for fixing rod ends after adjustment.
- EN 4693: Assembly codes A, B, and C for lower load tie rods.
- EN 4694: Assembly codes D, E, and F for higher load tie rods.
- EN 4695: Assembly codes G, H, and K for short-length tie rods with lower load ratings.
These linked standards ensure consistency throughout the product family, covering all components from assembly to locking mechanisms, thus providing a comprehensive framework for aerospace tie rod construction kits.
