SIST EN 4530-006:2009

Overview

SIST EN 4530-006:2009 is a European standard developed by CEN under the Aerospace and Defence Industries Association of Europe (ASD-STAN). It specifies product requirements for sealing sleeves designed for external diameter cables ranging from 4.68 mm to 5.05 mm. These sealing sleeves are used in connection elements according to EN 3155-002 and EN 4530-002 standards, primarily targeting aerospace applications. The standard details the required physical characteristics, testing protocols, designation, marking, and delivery conditions to ensure consistency, reliability, and safety in aerospace electrical systems.

Key Topics

• Scope and Application
  EN 4530-006 covers sealing sleeves specifically for cable diameters 4.68 mm to 5.05 mm used in aerospace electrical connections. It defines the physical, material, and performance criteria necessary for these components.

• Material Specifications
  The sealing sleeves must be made from fluoro silicone, a material known for its durability and resistance to a wide range of operating conditions.

• Temperature Range
  Classified as class R, these sealing sleeves are suitable for operating temperatures between −65 °C and 150 °C, making them reliable for harsh aerospace environments.

• Dimensional Requirements
  Precise dimensions and tolerances are specified to ensure compatibility with cables and connectors, preventing leakage and maintaining connection integrity.

• Testing and Quality Assurance
  The standard mandates compliance with several aerospace test methods outlined in EN 2591 series, including visual inspection, measurements of dimensions and mass, insulation resistance, voltage proof, temperature cycling, mould growth, salt mist resistance, immersion at low air pressure, fluid resistance, ozone resistance, and flammability.

• Assembly and Use Instructions
  Proper assembly guidelines indicate that the sealing sleeve must be positioned over the cable prior to contact assembly and slid into the connector cavity to ensure a proper seal.

• Designation and Packaging
  Each sealing sleeve is identified with a standardized code reflecting the cable diameter compatibility and standard number. Packaging must protect the product and include traceable manufacturer details and date codes.

Applications

• Aerospace Electrical Systems
  EN 4530-006 sealing sleeves are designed for aerospace electrical connectors, ensuring environmental sealing and mechanical protection in aircraft wiring and electronic systems.

• Harsh Environment Protection
  These sleeves provide resistance against temperature extremes, ozone, salt mist, and various fluids, making them suitable for avionics, satellite, and space vehicle applications.

• Connector Reliability
  By maintaining insulation and preventing ingress of contaminants, the sealing sleeves uphold electrical integrity and reduce failure rates in critical aerospace connections.
