Overview

SIST EN 4114:2024 is a European standard developed by CEN that specifies the dimensions, masses, and required characteristics of aerospace-grade loop clamps ("P" type) manufactured from aluminium alloy with various rubber cushioning materials. These clamps are critical components designed to support aerospace pipe assemblies and electrical cable bundles securely. The standard ensures consistent quality, safety, and performance of clamps used primarily in aerospace applications operating at temperatures up to 80 °C, with higher temperature use subject to user discretion.

This standard replaces EN 4114:2009, reflecting updates in normative references and terminology. It applies specifically to loop style clamps made with aluminium alloy AL-P5086-H111 and includes detailed provisions regarding materials, surface treatments, and configurations.

Key Topics

• Clamp Materials and Cushioning
  The clamps are made from aluminium alloy specified in EN 2693, ensuring lightweight and corrosion-resistant properties suitable for aerospace environments. Cushion materials conform to EN 4115 and include:

  • Silicone rubber (VMQ) - rust color
  • Fluorosilicone rubber (FVMQ) - blue color
  • Fluorocarbon rubber (FKM) - brown color
    These elastomers provide vibration damping, protection against mechanical stress, and environmental resistance.

• Surface Treatments
  Clamps receive optional surface treatments to enhance durability:

  • No treatment (code 0)
  • Yellow chromate conversion coating per EN 2437 (code 1) for corrosion protection.

• Dimensions and Masses
  The standard provides comprehensive tables and figures detailing clamp dimensions, tolerance levels, and mass data corresponding to different cushion types and pipe diameters. This technical specification guarantees proper fit and compatibility with aerospace pipes and cables.

• Designation and Marking
  EN 4114 specifies a systematic designation format to identify clamp types, hole versions, cushion materials, wedged cushions, and surface treatments through color coding and alphanumeric codes. Marking requirements align with EN 2424 to ensure traceability and compliance in aerospace manufacturing and maintenance.

Applications

SIST EN 4114:2024 clamps play a vital role in aerospace engineering by:

• Supporting piping systems for fuel, hydraulic, and pneumatic lines in aircraft and spacecraft, ensuring secure mounting under vibration and temperature variation.
• Managing electrical cable bundles, maintaining electrical safety, and minimizing mechanical wear.
• Facilitating lightweight and corrosion-resistant mounting solutions, crucial for aerospace vehicle structural integrity and performance efficiency.
• Offering compatibility with various elastomer cushions that can withstand specific environmental conditions and temperature ranges.

These clamps are essential for aerospace manufacturers, maintenance organizations, and suppliers aiming to meet industry safety and quality standards.

Related Standards

For a comprehensive understanding and compliance, SIST EN 4114:2024 references several standards:

• EN 2693 - Aluminium alloy specifications for clamp manufacturing materials.
• EN 4115 - Dimensions and masses of rubber cushions for clamps.
• EN 3078 - Technical specifications for P, Q, and saddle clamps with rubber cushioning.
• EN 2437 - Standards for chromate conversion coatings for aluminium alloys.
• EN 2424 - Aerospace product marking requirements for traceability.
• Various elastomer standards including EN 2261 (Silicone VMQ), EN 3825/3826 (Fluorosilicone FVMQ), and EN 2566 (Fluorocarbon FKM) for cushion material properties.
