This standard contains materiel acquisition program planning and engineering direction for considering the influences that environmental stresses have on materiel throughout all phases of its service life. It is important to note that this document does not impose design or test specifications. Rather, it describes the environmental tailoring process that results in realistic materiel designs and test methods based on materiel system performance requirements

Method 500.5 Low Pressure Testing		Method 507.5 Humidity Testing
	Low-pressure (altitude) testing is performed to determine if materiel can withstand and/or operate in a low-pressure environment and/or withstand rapid pressure changes.		The purpose of this method is to determine the resistance of materiel to the effects of a warm, humid atmosphere.
Method 501.5 High Temperature Testing		Method 509.5 Salt Fog Testing
	High temperature testing is performed to obtain data to help evaluate effects of high temperature conditions on materiel safety, integrity, and performance		Salt fog testing is performed to determine the effectiveness of protective coatings and finishes on materials. It may also be applied to determine the effects of salt deposits on the physical and electrical aspects of materiel.
Method 502.5 Low Temperature Testing		Method 512.5 Immersion Testing (Procedure 1)
	Low temperature testing is performed to obtain data to help evaluate effects of low temperature conditions on materiel safety, integrity, and performance during storage, operation, and manipulation.		Immersion testing is performed to determine if materiel can withstand immersion or partial immersion in water (e.g., fording), and operate as required during or following immersion.
Method 503.5 Temperature Shock Testing		Method 514.5 Vibration Testing
	Temperature shock testing is performed to determine if materiel can withstand sudden changes in the temperature of the surrounding atmosphere without experiencing physical damage or deterioration in performance.		Vibration testing is performed to develop materiel to function in and withstand the vibration exposures of a life cycle including synergistic effects of other environmental factors, materiel duty cycle, and maintenance.
*Method 504.1 Fluid Contamination*		*Method 516.5 Mechanical Shock Testing*
	Contamination by fluids testing is performed to determine if materiel (or material samples) is affected by temporary exposure to contaminating fluids (liquids) such as may be encountered and applied during its life cycle, either occasionally, intermittently, or over extended periods.		Shock tests are performed to provide a degree of confidence that materiel can physically and functionally withstand the relatively infrequent, non-repetitive shocks encountered in handling, transportation, and service environments. This may include an assessment of the overall materiel system integrity for safety purposes in any one or all of the handling, transportation, and service environments; determine the materiel's fragility level, in order that packaging may be designed to protect the materiel's physical and functional integrity; and test the strength of devices that attach materiel to platforms that can crash.
