BS EN 3646-002 is a standard that covers performance and contact arrangements for couplings and connectors, ensuring stable operability and safety in high-temperature operations.
BS EN 3646-002 defines the performances and contact arrangements groups for bayonet coupling circular connectors, intended for use in an operating temperature range of − 65 °C to 175 °C or 200 °C continuous.
BS EN 3646-002 on performance and contact arrangements for couplings and connectors applies to:
Connectors are essentially enclosures that house connections with wires on electrical wiring harnesses. Couplings are used to join equipment and components together. Aerospace operations involve high temperatures, so the coupling and connectors should be able to sustain in high temperatures to provide performance, reliability, and durability in aerospace applications.
BS EN 3646-002 provides users guidance on operating conditions, including combinations of plugs and receptacles, combinations of protective covers and connectors, permissible cables, electrical conditions, climatic conditions, and mechanical conditions, enabling users to select and classify connectors and receptacles to ensure operational stability and performance.
BS EN 3646-002 provides users guidance on the type of codes, polarization, housing sizes and contact arrangements, enabling users to identify and classify for use case applicability and functionality in aerospace applications.
With obedience and compliance to BS EN 3646-002, users can develop and assess connectors and couplings to ensure stable operability, thermal resistance and strength in high-temperature operations.
