EN 4585:2003 - Aerospace series - Clips, spring tension - Technical specification

Overview

EN 4585:2003 - "Aerospace series - Clips, spring tension - Technical specification" (CEN) defines the characteristics, qualification and acceptance requirements for alloy-steel spring tension clips used to support electrical harnesses in aerospace applications. The standard applies whenever referenced in procurement or design documents and sets out test methods, sampling plans and marking/packaging requirements to ensure repeatable performance and airworthiness-compatible quality.

Key topics and technical requirements

  • Scope and materials: Spring tension clips in alloy steel for electrical harness retention; material conformity must be verified by chemical analysis or supplier certificate.
  • Quality assurance: Defines qualification (initial) and acceptance (batch) inspection regimes, including sample sizes and test allocation. Qualification is performed on each clip type/size (five samples as a baseline).
  • Dimensional and surface control: Gauging to the product definition; surface roughness per ISO 4288 and visual/non‑destructive inspection (penetrant testing per ISO 3452) to exclude cracks, seams, laps and harmful inclusions.
  • Retention resistance: Minimum radial retention forces specified by nominal clip size (see Figure 1 of EN 4585). Tests use a stainless-steel mandrel (Ra = 1.6 µm per ISO 4288) installed radially into the clip; tensile test machines measure pull‑out force.
  • Corrosion resistance: Clips must survive 50 cycles of immersion in (3.5 ± 0.1)% NaCl solution (8–10 min immersion, then dried to complete 1 h) without cracking, pitting, or intergranular attack when mounted on the mandrel.
  • Reusability (thermal cycling): Clips must retain specified retention force after thermal cycling at the maximum operating temperature (±10 °C) for repeated cycles; removal and retention checks are specified at set intervals.
  • Packaging & identification: Batch marking, labelling (part number, quantity, batch), and packaging to prevent corrosion or damage during handling and storage.
  • Sampling & AQL: Acceptance sampling plans reference ISO 2859‑1 with Acceptance Quality Limits (AQLs) tailored for defect severity (critical/major/minor).

Applications and who uses it

  • Aerospace hardware manufacturers and subcontractors producing or specifying spring tension clips for wiring harnesses.
  • Design and electrical-harness engineers choosing clips for routing, retention and vibration resilience.
  • Quality engineers and test laboratories performing qualification and batch acceptance tests.
  • Procurement teams and OEMs requiring compliance in supply contracts and part specifications.

Related standards

  • EN 9133 (aerospace quality systems - qualification procedure for standard parts)
  • TR 4586 (design recommendations for spring tension clips)
  • TR 4587 (assembly recommendations)
  • ISO 2859‑1, ISO 3452, ISO 4288 (sampling, penetrant testing, surface texture)

EN 4585:2003 ensures reliable harness retention through defined mechanical, corrosion and sampling requirements - essential for aerospace safety, traceability and supplier control.
