Overview
EN 2591-428:2002 is a CEN/AECMA aerospace test method that specifies how to assess the ability of crimped terminal lugs to withstand sinusoidal vibration while a current is passing through them. The procedure evaluates both mechanical and thermal effects of vibration plus electrical loading and is intended to be used together with EN 2591-100 (General test methods).
Key Topics and Requirements
- Scope: Method for crimped terminal lugs under sinusoidal vibration with passage of current.
- Specimen preparation: Specimens must be fitted with normal accessories and wired per the technical specification. The technical specification shall define: number of specimens, cable type, installation/wiring, initial measurements and pass/fail requirements.
- Equipment reference: Test equipment and set-up follow EN 2591-403 (sinusoidal and random vibration).
- Frequency range: 10 Hz to 2 000 Hz.
- Vibration amplitude: Below transition frequencies use constant displacement; above transition use constant acceleration. Default values are 0.75 mm displacement and 15 gn acceleration, unless otherwise specified.
- Test duration and cycles: One sweep from 10 Hz → 2 000 Hz → 10 Hz in 20 minutes. This cycle is repeated 12 times in each of three orthogonal directions (total 36 cycles, approx. 12 hours).
- Ageing current: During vibration an electrical current is applied sufficient to produce the specified ageing temperature in the cable core. The ageing (test) current is determined per cable type.
- Assembly and documentation: Assembly details, wiring and acceptance criteria are specified in the applicable technical specification.
Applications and Who Uses It
This standard is essential for:
- Aerospace electrical/harness design engineers validating the durability of crimped terminal lugs under combined mechanical and electrical stress.
- Qualification and acceptance test laboratories performing vibration testing with current for aircraft, satellite and defense wiring systems.
- Manufacturers of connectors, terminals and cable assemblies seeking compliance with aerospace elements of electrical and optical connection requirements.
- Quality, certification and procurement teams requiring standardized test evidence for component selection and supplier approval.
Practical uses include qualification of terminal lugs and cable assemblies for flight hardware, environmental qualification programs, and supplier conformity testing where vibration-induced heating or contact degradation is a concern.
