Overview
SIST EN 3373-014:2009 is a European standard published by the European Committee for Standardization (CEN) that defines product requirements for aerospace-grade in-line splices, insulated and sealed, designed for crimping on copper conductors. These splices are nickel plated and suitable for use on copper conductors with nickel plating, operating at temperatures up to 200 °C. The standard specifically covers splices that maintain high reliability under demanding aerospace environmental conditions and must be used alongside EN 3373-001, which provides the underlying technical specifications.
Key Topics
Scope and Purpose
This standard governs the physical, chemical, and electrical characteristics of sealed, insulated, nickel-plated in-line splices for aerospace electrical systems. It ensures compatibility with nickel-plated copper conductors and insulation rated at least 135 °C.Material Specifications
- Crimp barrels made of copper alloy per ASTM B75.
- Nickel plating on crimp barrels according to SAE-AMS-QQ-M-290.
- Insulating sleeves composed of heat-shrinkable, transparent blue radiation cross-linked modified fluoropolymer, equipped with meltable sealing rings for environmental protection.
Temperature Range
Operational from -65 °C to 200 °C, suitable for high-temperature aerospace applications.Design Features
Color-coded crimp barrels for easy identification, detailed in the documentation with specific dimensions and masses for each item code.Testing and Quality Assurance
Requires compliance with EN 3373-001 tests, including dielectric withstand voltage of 2,500 V DC for one minute and insulation resistance greater than 5,000 MΩ. Quality assurance processes align with aerospace industry standards for reliability and performance.Assembly and Tooling
Crimping tools must conform to MIL-DTL-22520/37, ensuring precise and consistent crimps. Heating devices for sealing must safely produce temperatures between 280 °C to 340 °C, with safeguards for use in flammable environments.Marking and Packaging
Markings include color bands on barrels correlating to conductor ranges, alongside manufacturer details, batch numbers, and dates on packaging for traceability.
Applications
SIST EN 3373-014:2009 splices are primarily used in aerospace electrical wiring systems including:
- Aircraft electrical harness assemblies requiring high-temperature resistance.
- Defense and space applications demanding robust, reliable electrical connections under thermal and environmental stress.
- Situations where sealed and insulated in-line splices prevent moisture ingress and ensure electrical safety.
- Maintenance and manufacturing of aerospace cables where nickel-plated copper conductors are involved.
This standard supports the production of components contributing to the overall safety, durability, and performance of aerospace electrical equipment operating in extreme conditions.
