SIST EN 3745-603:2008 – Aerospace Optical Fibre and Cable Radiation Testing
Overview
SIST EN 3745-603:2008 is a European standard developed by CEN under the Aerospace and Defence Industries Association of Europe (ASD-STAN). This standard defines test methods to assess the impact of nuclear radiation on the transmission capabilities of optical fibres and cables specifically designed for aircraft use. Given the critical role of optical fibre communication in aerospace systems, ensuring reliability under radiation exposure is essential for safety and performance.
This document provides a structured methodology for evaluating optical fibres and cables exposed to nuclear radiation environments, encompassing both background radiation and harsher adverse nuclear conditions. By standardizing these testing procedures, SIST EN 3745-603:2008 supports aerospace manufacturers and engineers in validating fibre optic components for mission-critical applications.
Key Topics
Scope
The standard focuses on determining radiation-induced degradation in optical fibre transmission caused by nuclear radiation exposure. It is applicable to aerospace optical fibres and cables used in aircraft systems.Test Specimen Preparation
Specimens are prepared and stabilized under standard test conditions for 24 hours prior to radiation exposure. Parameters including specimen length (typically 500m for background radiation, 100m for adverse environments), acceptable attenuation variation, test temperature, and measurement intervals must be specified.Radiation Exposure Methods
Two test methods address different radiation environments:- Method A – Environmental Background Radiation
Exposure to a Co-60 or equivalent gamma source at ~20 rad/h with a minimum total dose of 100 rad. - Method B – Adverse Nuclear Environment
Exposure to higher dose rates (5 to 250 rad/s) simulating intense nuclear conditions, with specified total dose/dose rate combinations to assess fibre endurance under severe radiation.
- Method A – Environmental Background Radiation
Apparatus Requirements
Testing requires:- Light Launch System (LLS) and Detection System (LDS) complying with EN 2591-100.
- A continuous power measurement and recording unit.
- Optical splitter or fibre coupler for reference path monitoring.
- Radiation source (Co-60 or equivalent) calibrated for dose uniformity using thermoluminescent dosimeters (TLDs).
- Temperature-controlled chamber maintaining ±2 °C stability.
Measurement Procedures and Criteria
Attenuation is measured before, during, and after radiation exposure following EN 3745-301 Method C. Maximum allowable attenuation changes are specified to confirm compliance. Post-irradiation tests verify the recovery and stability of fibre transmission properties.
Applications
Aerospace Fibre Optic Components
SIST EN 3745-603:2008 is integral for testing optical fibres and cables incorporated in aircraft and aerospace platforms, where environmental radiation can affect signal integrity.Aircraft Electrical and Communication Systems
Ensures reliable operation of communication, navigation, and control systems using optical fibres in nuclear radiation-prone conditions such as high-altitude flight or near nuclear facilities.Safety-Critical Systems Validation
Supports certification and qualification of fibre optic components for military and civilian aerospace equipment, meeting stringent industry requirements.
