Overview

EN 4710-04:2015 - Aerospace series: Quick release fastening systems for non-structural applications - Part 04: Spring clamp (one way tolerance compensation) is a European standard published by CEN. It specifies the dimensions, mass, tolerances and static values for catch spring (spring clamp) components used in fuselage interior equipment and other non‑structural or secondary structural areas. The standard covers environmental limits (‑55 °C to 85 °C) and is intended for use together with other EN 4710 series parts.

Key topics and technical requirements

• Scope: Spring clamp for non‑structural aerospace applications (one‑way tolerance compensation).
• Dimensions & mass: Two type codes are defined (CTS and CTM) with detailed dimensional tables and approximate masses (CTS ≈ 0.9 g; CTM ≈ 2.3 g). Unspecified tolerances follow ISO 2768‑mK (EN 22768‑1/2).
• Mechanical performance: Ultimate loads specified by type (example: CTS = 500 N; CTM = 900 N).
• Materials & surface treatment:
  • Material code S: Stainless steel 1.4310 (EN 10151), passivated per EN 2516.
  • Material code A: Alloy steels (1.0605 or 1.1248 per EN 10132‑4) with electroplated coating per DIN 50979.
• Endurance: Cycle life requirements differ by material code (Material A: 1 500 cycles; Material S: 500 cycles).
• Marking & identification: Product marking per EN 2424 (style F). Designation example: EN4710-04CTM4S (standard-family-type-plate-material).
• Testing & inspection: Acceptance and qualification tests referenced to EN 4710‑01 and summarized in the standard (dimensions, materials, surface treatment, ultimate loads, corrosion resistance, functionality, etc.).
• Temperature range: Applicable service/test range is -55 °C to 85 °C.

Applications and users

• Practical applications: Quick‑release spring clamps for interior panels, fittings, trim, access panels and other non‑structural attachments in aircraft fuselage interiors where a one‑way tolerance compensation is required.
• Who uses this standard: Aerospace component designers, interior systems engineers, manufacturers of fasteners and spring clamps, quality/inspection teams, procurement and certification authorities, and test laboratories responsible for acceptance and qualification testing.

Related standards

• EN 4710‑01 (technical specification / testing references)
• EN 4710‑02, EN 4710‑06, EN 4710‑07 (related parts of the quick release fastening family)
• EN 2424 (marking), EN 2516 (passivation), EN 10132‑4 / EN 10151 (material delivery conditions), EN 22768‑1/2 (general tolerances), DIN 50979 (electroplating)
