Overview
SIST EN 6059-505:2025 is a European standard developed by CEN that specifies test methods for evaluating the resistance of aerospace electrical cable protection sleeves to simulated lightning strikes and current pulses. This standard is part of the aerospace series covering electrical cables and their installation, with a particular focus on protection sleeves used to safeguard wiring harnesses from lightning-induced damage.
The document defines a rigorous procedure to simulate lightning strike conditions on protection sleeves, measuring their ability to withstand high current and voltage pulses without failure. SIST EN 6059-505:2025 is essential for ensuring the integrity and reliability of electrical installations in aerospace applications, where exposure to lightning strikes poses significant risks.
Key Topics
- Testing Scope: Measures the capability of protective sleeves to endure specified severities of simulated lightning strikes and current pulses.
- Specimen Preparation: Requires testing of smallest, medium, and largest sizes of protection sleeves over standard cable bundles, with specific installation methods including conductive terminations and grounding.
- High Current Pulses: Defines pulse classes ranging from 1 kA to 30 kA peak currents to represent lightning parameters for different severity levels.
- Test Procedure: Includes ten current pulses per sample with minimum 1-minute intervals, alongside mandatory pre-conditioning tests such as visual inspection and electrical continuity verification.
- Apparatus Requirements: Calls for a power generator capable of producing defined current waveforms and measurement devices to record current parameters during testing.
- Final Assessment: Post-test visual inspections and electrical resistance measurements ensure the sleeve retains protective functionality and complies with product standards.
- Compliance: The sleeve must meet additional requirements set out in the product-specific standards referenced, such as EN 6059-201 and EN 3475-301.
Applications
SIST EN 6059-505:2025 is primarily intended for aerospace manufacturers, suppliers, and testing laboratories involved in:
- Design and certification of electrical cable protection sleeves used in aircraft and spacecraft.
- Quality assurance during production processes, verifying sleeve durability against lightning strikes.
- Safety compliance with aerospace industry requirements for electrical installation robustness.
- Research and development assessing new materials or sleeve constructions under lightning simulation.
- Maintenance and inspections to evaluate in-service sleeve condition after exposure to severe electrical events.
By applying this standard, aerospace organizations enhance the electrical system safety, minimizing risks of electrical failures due to lightning-induced surges, which could compromise flight safety and operational reliability.
