|Types of Process/Test||Purpose||Performed on||Attempts to simulate service environment|
|Element Development||Early verification that components,materials and concepts will meet specifications.||Samples and prototypes||Yes|
|Design Verifications||Verify that systems will meet design specifications||As close to production configuration as possible||Yes|
|Reliability Development||Find and eliminate design and process items that reduce reliablity||As close to production configuration as possible||NO (But sometimes misguidedly tries)|
|Environmental Stress Screening||Transform latent failures into patent failures before delivery to the end user||Production hardware||NO|
Climatics is the science of measuring,analyzing,controlling and testing with climatic,weather,or meteorological conditions.
Although they are usually thought of as being natural environments,they are often created or modified by man.
Climatics deals with variables of temperature,pressure,moisture,corrosive environments,sand&dust,icing,solar radiation,and combinations.
