MIL-STD-810 Method 500 Low-Pressure Altitude Testing

MIL-STD-810, Method 500, covers the testing of equipment in low-pressure altitude environments. This method is used to assess the equipment's performance and functionality when exposed to low atmospheric pressure conditions, such as those experienced at high altitudes or during transportation in low-pressure environments. 

Clark Testing engineers conduct low-pressure altitude testing to evaluate the equipment's ability to operate, withstand, and maintain its performance in low-pressure conditions. The tests help identify potential issues related to pressure differentials, material integrity, sealing, and functionality.

MIL-STD-810 Method 500 provides detailed procedures for conducting low-pressure altitude testing. The test typically involves subjecting the equipment to a simulated low-pressure environment using a vacuum chamber or altitude chamber. Test profiles are developed to determine pressure levels, ramp rates, and duration of the tests based on the equipment's intended use and the operating environmental conditions. 

MIL-STD-810G specifies different low-pressure altitude test levels that are categorized based on the anticipated pressure conditions. The levels are determined considering factors such as altitude, flight profiles, transportation conditions, and deployment scenarios. Using these metrics, Clark Testing will help ensure that the equipment is tested under relevant and representative low-pressure conditions. 

The standard defines acceptance criteria for low-pressure altitude testing. The criteria may include allowable pressure differentials, material deformations, sealing integrity, functionality, and other performance parameters. The equipment is assessed based on its ability to maintain its functionality and structural integrity within the specified low-pressure environment. 

The engineers at Clark Testing help our customers identify potential issues related to pressure differentials, material integrity, sealing, and functionality.  Call or email Clark Dynamics Test Laboratory for assistance in developing the appropriate test plan and qualifying your equipment to MIL-STD-810 Method 500.
