Overview
SIST EN 3475-505:2023 is a European standard established by CEN that specifies the test method for assessing the tensile properties of electrical conductors used in aerospace applications. This standard applies to stranded conductors, single strands, solid conductors, and braids used in aircraft wiring systems. It is essential for verifying the mechanical strength of conductors to ensure safety, reliability, and compliance with aerospace requirements.
The standard allows tensile testing on insulated wires and cables after insulation removal and is designed to be used alongside EN 3475-100, which covers general test methods for aerospace electrical cables. SIST EN 3475-505:2023 updates and supersedes the 2012 edition, incorporating refined definitions, apparatus specifications, and testing procedures.
Key Topics
Scope and Application
Defines the tensile test procedures for different types of conductors and cable braids to measure tensile strength, elongation, yield strength, and breaking load.Terminology and Definitions
Clarifies critical terms such as breaking load, maximum load, tensile strength, elongation at break, elastic limit, and yield strength to ensure consistent understanding.Apparatus Requirements
Specifies the use of tensile testers capable of accurate load and elongation measurement (±1% accuracy), with defined jaw design, specimen length (250 ± 5 mm), and pulling speed (50 ± 10 mm/min).Testing Methods
- Stranded Conductors: Tests whole conductors for smaller cross-sections or individual strands for larger ones, reporting average values from three samples.
- Single Strand/Solid Conductors: Tests three samples, calculating average tensile properties.
- Braids: Requires stripping the cable jacket carefully, pulling off the braid, and testing under controlled preload conditions.
Measurement and Reporting
Emphasizes the importance of removing conductor slack and producing fracture in the test specimen center, ensuring accurate measurement of tensile properties including breaking load and elongation.Requirements Conformance
Test results must conform to values specified in the product standard used alongside EN 3475-505, guaranteeing material and product compliance.
Applications
SIST EN 3475-505:2023 is critical for aerospace manufacturers, cable suppliers, quality assurance professionals, and testing laboratories involved in the design, production, and certification of aircraft electrical wiring systems. It ensures:
- Material Verification: Confirms tensile strength and mechanical durability of conductors to withstand aircraft operational stresses.
- Safety Compliance: Supports adherence to aerospace regulations and product standards, reducing electrical system failures.
- Quality Control: Provides a standardized test to assess conductor integrity, enabling identification of defective wire batches before installation.
- Design Optimization: Informs conductor and cable design improvements by evaluating tensile behavior under controlled conditions.
