Reliability Test Analogy The Seaside Salty Environment

This document summarizes the results of reliability tests conducted on various parts of a Trane/IR EGI:SECC-P air conditioner unit exposed to a salty environment. The tests evaluated corrosion resistance by exposing parts to salt spray or high humidity at elevated temperatures for periods up to 1000 hours. Most parts passed the tests without any blistering, rusting, cracking or coating loss, indicating good corrosion resistance in salty environments.
