EN 2591-213:1997

Overview

EN 2591-213:1997 is a European standard developed by CEN that defines the test methods for measuring the shielding effectiveness of aerospace electrical and optical connection elements. Specifically, it addresses the frequency range from 100 MHz to 1 GHz, focusing on connection components fitted with screen clamping back-shells. The standard is part of the aerospace series concerning electrical and optical connection elements and is designed to be used in conjunction with the main EN 2591 standard.

This method ensures that connection elements provide adequate electromagnetic shielding to reduce electromagnetic interference (EMI) in aerospace applications, thereby improving system reliability and safety.

Key Topics

• Shielding Effectiveness Measurement
  Method to quantify how well connection elements prevent electromagnetic fields in the 100 MHz to 1 GHz range from penetrating or escaping through the shielded connection points.

• Screen Clamping Back-Shells
  Testing focuses on connection parts equipped with back-shells designed to clamp the screen or shield on cables, an essential feature for maintaining shielding continuity.

• Frequency Range Coverage
  Ensures comprehensive testing within the critical 100 MHz to 1 GHz spectrum, which covers many communication and radar frequencies relevant in aerospace systems.

• Reference Integration
  This part (Part 213) is intended to be used along with the general standard EN 2591, which provides overall requirements and testing for electrical and optical connection elements.

Applications

• Aerospace Electrical Systems
  Ensures connectors and cable assemblies in aircraft and spacecraft meet rigorous shielding demands, mitigating electromagnetic interference that could impact avionics and control systems.

• Optical Connection Components
  Although primarily addressing electrical connectors, the standard also relates to optical connection elements where electromagnetic shielding is necessary.

• Quality Assurance and Compliance
  Manufacturers and testing laboratories utilize EN 2591-213 to verify product compliance, ensuring components maintain shielding effectiveness over the specified frequency range.

• System Integration and Maintenance
  Helps aerospace engineers assess shielding performance during system design, integration, and troubleshooting phases, thus improving EMI mitigation strategies.

Related Standards

• EN 2591 (General Series)
  The foundational aerospace series standard for electrical and optical connection elements-setting broad requirements to which Part 213 adds specific shielding test methods.

• Other EN 2591 Parts
  Cover different aspects of testing and performance requirements for aerospace connectors, including mechanical, environmental, and electrical characteristics.

• International Electrotechnical Commission (IEC) Standards
  Complementary standards related to EMI/EMC testing and connector qualification can enhance the robustness of compliance strategies.

Following the guidelines of EN 2591-213:1997 supports aerospace manufacturers and suppliers in ensuring their connectors meet stringent shielding effectiveness criteria, maintaining electromagnetic compatibility in complex aerospace environments. Adhering to these test methods contributes significantly to operational safety and system reliability.
