Environmental Stress Screening (ESS) is a series of tests conducted under environmental stresses to expose weak parts and defects in workmanship so they may be corrected.  It’s designed to remove latent part and manufacturing process defects through the application of environmental stimuli (e.g., random vibration, thermal cycling) prior to fielding equipment. [2] Random vibration and …
