scope:

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 compatibility 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.

Purpose

This SAE Recommended Practice (ARP) serves as a guide to assist users in choosing compatible connector/accessory finish/plating combinations to achieve the best corrosion resistance performance. Failure to select and employ suitable finish/plating combinations, may negatively impact reliability (service life) and performance of individual EWIS components, and the entire system in which it is installed.
