Overview

SIST EN 4710-005:2015 is a European standard developed by CEN specifying the technical requirements and characteristics of quick release fastening systems for aerospace non-structural applications. This part of the aerospace series focuses specifically on the spring clamp with two ways tolerance compensation, used primarily in fuselage interior equipment and secondary structural areas.

Engineered for reliable performance in the demanding aerospace environment, the standard outlines precise dimensions, mass, tolerances, mechanical properties, and material requirements for catch springs. It complements related parts EN 4710-06 and EN 4710-07 under the framework established by EN 4710-02.

The defined operating temperature range between -55 °C and 85 °C supports applicability in a wide spectrum of aircraft interior conditions.

Key Topics

• Dimensions & Configuration
  The standard details all critical dimensions and mass values, including tolerance ranges per ISO 2768 standards, to ensure interchangeability and quality control.

• Mechanical Performance
  It specifies ultimate load limits for spring clamps to guarantee secure fastening under static conditions typical for aircraft interiors.

• Material Specification
  Materials include stainless steel (1.4310) and selected alloy steels (1.0605 or 1.1248), with surface treatments like electroplated coatings or passivation, aligned with European material standards (EN 10151, EN 2516, DIN 50979).

• Marking & Identification
  Marking requirements follow EN 2424 to ensure traceability and compliance, encompassing both product and packaging identification.

• Testing & Qualification
  Rigorous acceptance and qualification tests are mandated, including surface finish inspections, corrosion resistance checks, tensile load verification, and endurance cycles (minimum 500 to 1500 cycles depending on material).

• Two Ways Tolerance Compensation
  Design features allow the spring clamps to accommodate dimensional variations in two directions, enhancing installation flexibility and reducing the risk of assembly errors in non-structural aerospace components.

Applications

SIST EN 4710-005:2015 spring clamps are integral in aerospace non-structural fastening tasks, including:

• Securing interior equipment components such as panels, trims, and secondary structures within an aircraft fuselage
• Providing quick-release functionality for maintenance and assembly efficiency
• Accommodating dimensional deviations during installation thanks to dual-tolerance compensation, improving reliability and serviceability
• Serving in environments demanding compliance with specified temperature ranges and corrosion resistance

These fastening systems are critical for aerospace manufacturers, maintenance organizations, and suppliers aiming to meet stringent safety, durability, and interchangeability requirements.
