Overview

SIST EN 4710-007:2015 is a European Standard published by CEN, specifying the quick release retaining grommets used in aerospace non-structural applications, particularly for fuselage interior equipment. It defines the dimensional, mass, and tolerance requirements essential for ensuring compatibility and reliability in aerospace environments. This standard is designed to be used alongside EN 4710-06 and EN 4710-02 for comprehensive quick release fastening system conformity.

The standard covers retaining grommets suitable for operating within an ambient temperature range from -55 °C to 85 °C, aligning with aerospace industry demands for durable components in varying thermal conditions.

Key Topics

• Scope and Application
  SIST EN 4710-007:2015 specifically addresses the dimensions, tolerances, and mass of retaining grommets for use on fuselage interiors and other non-structural or secondary structural zones within aerospace assemblies.

• Design and Dimensions
  The standard provides detailed dimensional charts, including configurations and tolerances compliant with ISO 2768-mK for linear and angular measurements.
  Key dimension parameters include:

  • Outer and inner diameters
  • Length codes and mass for different grommet types (RS, RM, RL)

• Material Specifications
  The retaining grommets are made of silicone rubber with a hardness specified at 60 ± 5 Shore A (IHDC), ensuring appropriate flexibility and resilience without a live limit.

• Marking Requirements
  The grommets must be marked following EN 2424 style G, which ensures traceability and conformity with aerospace product marking standards.

• Testing and Qualification
  Acceptance and qualification tests cover:

  • Material verification
  • Dimensional accuracy
  • Surface quality (defect inspection)
  • Burning behavior
  • Functional performance
    Testing protocols refer to requirements established in EN 4710-01, maintaining consistency across the aerospace quick release fastening series.

Applications

SIST EN 4710-007:2015 retaining grommets are primarily used within aerospace fuselage interiors and secondary structural areas where secure yet quick-release fastening solutions are critical. Common practical applications include:

• Interior panels and equipment attachments in aircraft cabins
• Non-structural fastening points requiring vibration resistance and environmental stability
• Secondary structural assemblies where ease of maintenance and part replacement is essential
• Use in environmental conditions ranging from subzero to high ambient temperatures (-55 °C to 85 °C)

By following this standard, manufacturers and aerospace engineers can ensure that retaining grommets meet rigorous durability, size, and functional standards indispensable for aircraft safety and maintenance efficiency.

Related Standards

EN 4710-07 should be used in conjunction with related parts of the aerospace quick release fastening system series for comprehensive compliance:

• EN 4710-01: Quick release fastening systems – Technical specification
• EN 4710-02: Spring clamp stud combination
• EN 4710-06: Stud - quick-release and locking mechanisms
• EN 2424: Marking of aerospace products
• EN 22768-1 and EN 22768-2: General tolerances for linear, angular, and geometrical dimensions without individual tolerance indications

Together, these standards harmonize the aerospace fastening components’ design, testing, and application for non-structural aerospace equipment ensuring interchangeability and safety.
