Guide for Achieving Plating/Finish Compatibility with Connectors and Accessories used in Electrical Wiring Interconnect Systems (EWIS)
The intent of this ARP is to provide guidance to assist users in choosing compatible component finishes/platings to achieve the best corrosion resistance performance for compatible components/couples. This SAE Recommended Practice is intended as a guide toward standard practice and is subject to change to keep pace with experience and technical advances. A galvanic compatibililty table is provided to assist with the compatible plating/finish selection. Specific plating performance parameters for each individual plating and each connector/accessory specification have also been provided to assist the product user with compatible plating/finish selection.
Rationale: This document provides users a means to identify and select compatible galvanic couples to achieve the best connector and accessory plating/finish performance. Individual component specifications do not address finish selection for different plating configurations affecting the entire EWIS performance as a system (Backshell to Connector Plug to Connector Receptacle to Backshell).
