EN 2591-408:1998

Overview

EN 2591-408:1998 is part of the aerospace series of standards focusing on elements of electrical and optical connection. This specific standard outlines the test methods for measuring mating and unmating forces of connection elements used in aerospace applications. It is designed to ensure reliable and consistent performance of connectors by specifying how to accurately assess the forces involved when connectors are joined and separated. EN 2591-408:1998 functions in conjunction with the broader EN 2591 standard, providing detailed procedures essential for quality control and compliance within the aerospace industry.

Key Topics

• Mating Forces Measurement: Defines the process for determining the force required to engage (mate) electrical and optical connectors, ensuring secure and stable connections during assembly.
• Unmating Forces Measurement: Specifies methods to measure the force necessary to disconnect connectors without causing damage, supporting safe maintenance and replacement operations.
• Test Method Consistency: Emphasizes repeatability and accuracy in testing methodology to provide reliable data critical for product validation.
• Scope of Application: Applied to both electrical and optical elements, reflecting the dual nature of aerospace connection requirements.
• Integration with EN 2591: This part is intended to be used together with the main EN 2591 standard, which covers wider aspects of connection elements.

Applications

EN 2591-408:1998 is essential for companies and organizations involved in the design, manufacturing, and certification of aerospace connectors. Its practical applications include:

• Connector Design Validation: Ensuring new connector models meet required force specifications for mating and unmating.
• Manufacturing Quality Control: Monitoring forces during production to detect variations that could affect performance or reliability.
• Maintenance and Repair: Guiding maintenance teams on the acceptable force ranges for disassembly, minimizing risk of connector damage.
• Aerospace Equipment Testing: Supporting qualification tests for electrical and optical connectors used in avionics, aircraft systems, and spacecraft.
• Supplier Assessments: Providing a standardized benchmark to evaluate the quality consistency of connectors sourced from various manufacturers.

Related Standards

For comprehensive understanding and compliance in aerospace electrical and optical connection testing, EN 2591-408:1998 should be used alongside these related standards:

• EN 2591 (Aerospace series - Elements of electrical and optical connection - General requirements): The main standard covering general aspects of connection elements.
• IEC 60512 (Connectors for electronic equipment – Tests and measurements): A broader international standard for testing connector interfaces.
• EN 364 (Aerospace - Electrical contacts and connection elements - Test methods): Includes additional test procedures relevant to connector durability and performance.
• MIL-STD-1344 (Test methods for electrical connectors): US military standard often referenced for aerospace connector testing protocols.

By adhering to EN 2591-408:1998, aerospace manufacturers and testing laboratories ensure that electrical and optical connectors meet stringent mechanical requirements for engagement and separation forces. This elevates connector reliability, contributes to system safety, and supports interoperability across aerospace components-making it a critical standard in aerospace electrical and optical connection technology.
