Overview

SIST EN 2591-613:2004 is a European aerospace standard that specifies test methods for assessing the impact resistance of optical elements used in electrical and optical connections. This includes optical connection elements, permanent connections, and fibre optic couplers. The standard is developed by CEN (European Committee for Standardization) and is part of the broader EN 2591 aerospace series.

The standard is essential for ensuring the durability and reliability of optical elements subject to mechanical impacts in aerospace applications. It is designed to be used together with EN 2591-100, which defines general test methods for electrical and optical connection elements in aerospace systems.

Key Topics

• Scope and Purpose
  EN 2591-613 defines procedures to test optical elements’ resistance to impact on a hard surface. This is critical in aerospace environments where components may face mechanical stresses during operation or handling.

• Reference Standards
  The standard complements and references other parts of the EN 2591 series, including:

  • EN 2591-100: General test methods
  • EN 2591-408: Mating and unmating forces
  • EN 2591-601: Optical elements – Insertion loss
  • EN 2591-6101: Optical elements – Visual examination
  • TR 4257: Numbering system relationships

• Test Apparatus and Setup
  The impact test requires a mounting fixture that holds the specimen horizontally at a specified height. The specimen is dropped onto a steel impact plate complying with size and thickness requirements. The cable and fixture setup follows strict conditions to ensure reproducibility.

• Test Procedure

  • Specimens stabilized at standard conditions for 24 hours before testing.
  • Impact tests are performed by dropping the specimen using a pendulum-type movement from defined heights representing light and severe impact levels.
  • The specimen is tested at 8 different orientations by rotating the mounting fixture.
  • Impact severity levels include:
    • Light: 8 drops from 1.80 meters
    • Severe: 16 drops from 2.40 meters
  • After each cycle of impacts, the specimen undergoes functional tests such as insertion loss and visual examination.

• Evaluation and Requirements
  Post-impact tests validate that optical elements maintain acceptable insertion loss and physical integrity, as specified by associated standards like EN 2591-601 and EN 2591-6101.

Applications

SIST EN 2591-613:2004 is predominantly applied in the following areas:

• Aerospace Industry
  Ensuring optical elements in aircraft and spacecraft connectors can withstand mechanical shocks and impacts during assembly, operation, and maintenance without degradation of optical performance.

• Quality Assurance and Compliance
  Manufacturers of optical connectors and fibre optic couplers use the standard to certify their products meet stringent aerospace requirements for mechanical durability.

• Research and Development
  Provides a consistent framework for testing new optical connection technologies and materials destined for aerospace applications.

• Maintenance and Inspection Protocols
  Supports periodic testing and evaluation in service to detect potential damage from impact events.
