Overview
The oSIST prEN 3155-065:2026 standard, developed by the Slovenian Institute for Standardization (SIST), specifies the product requirements, verification tests, and tooling for male electrical contacts, type A, crimp, class S, size 8, in the aerospace industry. These contacts are intended for use in electronic connection elements and are compatible with connectors from the EN 3645 and EN 4165 series. The standard aligns with the broader EN 3155 series, supporting high reliability in demanding aerospace environments.
Key Topics
- Contact Characteristics: This standard defines type A male electrical contacts, with a crimp connection and class S (−65 °C to 200 °C operating range), in size 8. The material is a copper alloy with gold-plated protection.
- Compatibility: Contacts are designed for use within connectors complying with EN 3645 and EN 4165, and with compatible female contacts defined in EN 3155-083.
- Tooling Requirements: Crimping tools must conform to SAE-AS22520, while insertion/extraction tools are specified by SAE-AS81969, ensuring standardized installation and removal procedures.
- Testing and Performance: Specifies comprehensive test regimes based on EN 2591 series methods, covering electrical resistance, endurance at elevated temperature, vibration, mechanical robustness, and environmental resistance (e.g., salt mist, rapid temperature change).
- Marking and Identification: Requires color coding according to ISO 8843, and allows for clear identification through marking and product coding.
Applications
Aerospace Electrical Systems
- Aerospace Connectors: These male electrical contacts are widely used in aerospace wiring harnesses, avionics modules, and power distribution units, providing robust and high-reliability connections.
- Qualified for Harsh Environments: The class S temperature rating and corrosion-resistant materials are specifically suitable for the operational extremes found in aircraft and space systems.
- Maintenance and Interchangeability: Standardized dimensions and tooling facilitate easier maintenance, inspection, and replacement in the field, supporting lifecycle management for aircraft electrical systems.
- Cross-Compatibility: By complying with EN 3155-002 and being compatible with both EN 3645 and EN 4165 connector series, these contacts ensure interoperability across a variety of aerospace platforms.
