Types of environmental tests

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.
