Overview
The kSIST FprEN 3155-017:2025 standard, developed by CEN and ASD-STAN, defines the product requirements for female electrical contacts (type A, crimp, class P) used in aerospace relay bases. This part of the Aerospace series focuses on the electrical contacts employed in connection elements, specifically for relay base applications as per EN 3155-002. Serving as a complementary standard to EN 3155-001, it details the mandatory characteristics, tests, tooling, and marking requirements to ensure performance, reliability, and safety in high-demand aerospace electrical systems.
Key Topics
- Scope and Application: Applies to female type A crimp contacts, class P, designed for use in relay bases operating in extreme aerospace environments up to 25,000 meters altitude and temperatures ranging from −65 °C to 125 °C.
- Characteristics:
- Material: Copper alloy body with gold plating for enhanced conductivity and corrosion resistance.
- Dimensions: Meticulously defined contact and barrel sizes, ensuring interchangeability and compliance across aerospace components.
- Temperature Rating: Class P contacts are rated for continuous operation up to 125 °C.
- Marking and Identification: Contacts are marked with distinctive color codes consistent with ISO 8843, simplifying size identification and installation.
- Permissible Cables: Specifies compatible cable sizes (AWG and mm²) and current ratings for various contact sizes to guarantee optimal crimp connections.
- Tooling Specifications: Includes approved crimping tools (conforming to SAE-AS 22520) and insertion/extraction tools (according to SAE-AS 81969), ensuring correct assembly and maintenance.
- Crimping and Cable Preparation: Defines cable stripping lengths and crimping parameters, critical for maintaining mechanical and electrical integrity.
- Testing Procedures: Requires rigorous testing according to EN 2591 series to verify performance under environmental stresses such as temperature cycling, vibration, shock, salt mist exposure, and mechanical endurance.
- Gauge Requirements: Establishes precise gauges for insertion and extraction force measurement, ensuring reliable contact retention and service life.
Applications
The contacts specified by kSIST FprEN 3155-017:2025 are vital components in aerospace electrical systems, particularly for relay base connections in:
- Commercial and military aircraft electrical installations.
- Spacecraft and satellites requiring highly reliable electrical connectors.
