EN 4662:2010 - Aerospace series - Test specification for vibration control components

Overview

EN 4662:2010 - Aerospace series - Test specification for vibration control components (CEN) defines standardized procedures and parameters for measuring static and dynamic stiffness of vibration control components used in aircraft (for example, shock mounts with bushes). Prepared under ASD-STAN and adopted by CEN, this test specification is intended to be applied where referenced in a product standard or a design specification for aircraft installations.

Key topics and requirements

  • Scope: Applies to vibration control components installed in aircraft applications; covers both translation and rotation directions using a Cartesian coordinate system.
  • Test setup: Test rigs must reproduce real aircraft installation interfaces, be as rigid as possible, and support maximum loads without significant deformation (specimen and original aircraft parts excluded). For dynamic tests the assembly must be resonance-free up to at least twice the maximum test frequency.
  • Static stiffness testing:
    • Specifies pre-load and test cycles, measurement data (load vs displacement or torque vs angle).
    • Measurement sample rate: > 100 samples per relevant event.
    • Defines hysteresis representation, secant stiffness calculation (C1/2, C5/6, C1-6), and resulting static stiffness Cstat.
    • Requires determination and subtraction of parasitic (correction) stiffness Ck by substituting the specimen with a rigid dummy using the same test parameters.
    • Environmental temperature T is controlled per the relevant product standard.
  • Dynamic stiffness testing:
    • Measures dynamic stiffness (Cdyn) and loss angle (ϕdyn) versus frequency (f).
    • Test parameters include static pre-load (Fpre), amplitude (A), and maximum test frequency (fmax).
    • Measurement sample rate: > 100; temperature controlled as specified.
  • Symbols and definitions: Standardizes notation for loads, displacements, torques and angles to ensure consistent reporting.

Applications and users

EN 4662:2010 is used by:

  • Aerospace component manufacturers (design verification and production testing of shock mounts, vibration isolators).
  • Test laboratories performing stiffness and vibration-control qualification.
  • Structural and vibration engineers specifying component performance in design documents.
  • Procurement and certification authorities requiring standardized test evidence for aircraft installations.

Practical benefits include repeatable stiffness characterization, consistent hysteresis reporting, and reliable dynamic stiffness / loss-angle curves for system-level vibration and shock analyses.

Related standards

  • EN 4662:2010 is an ASD-STAN/CEN aerospace series document and is intended to be referenced by specific product standards or design specifications. Test rig, environmental, and product-specific parameters should be aligned with the relevant product standard(s) and certification requirements.
