EN 2591-407:1999

Overview

EN 2591-407:1999 is a European standard developed by CEN focused on the aerospace industry. It belongs to the aerospace series covering elements of electrical and optical connection. This specific part, Part 407, defines test methods to assess the durability of contact retention systems and seals under conditions involving repeated contact insertion and extraction. The durability assessment ensures long-term reliability and safety in critical aerospace electrical and optical connection components. This standard is intended to be used in conjunction with EN 2591 to provide comprehensive testing protocols.

Key Topics

• Durability Testing Methods
  EN 2591-407 provides standardized procedures to simulate real-world mechanical stresses on connectors, focusing on the endurance of both contact retention systems and sealing components.

• Contact Retention System
  The document evaluates how well contacts remain secured within connectors after numerous engagement cycles, crucial for maintaining electrical and optical signal integrity.

• Seal Integrity
  Tests verify the ability of seals to maintain environmental protection (against dust, moisture, and other contaminants) after repeated mechanical usage.

• Repeated Insertion/Extraction Cycles
  The standard simulates frequent connection and disconnection events which aerospace equipment encounters, ensuring components stand up to rigorous operational demands.

• Compatibility with EN 2591 Series
  EN 2591-407 complements other parts of the EN 2591 series, offering a complete framework for testing aerospace electrical and optical connectors.

Applications

• Aerospace Electrical Systems
  Critical aerospace systems rely on robust connectors; applying this standard helps verify that contact retention and seals remain functional over the lifecycle of aircraft or spacecraft.

• Optical Communication Connections
  Ensuring optical connectors maintain mechanical durability and environmental sealing is vital for high-speed data transmission in aerospace environments.

• Quality Assurance and Compliance
  Manufacturers and suppliers of aerospace connector components use EN 2591-407 testing methods to demonstrate product reliability and comply with international aerospace standards.

• Maintenance and Inspection Protocols
  Aerospace maintenance teams can use insights from this standard to develop inspection schedules and predict potential connector wear or failure.

Related Standards
