High Altitude Low Pressure Simulation Test Chamber; low air pressure test applications

Low pressure test is mainly used in aviation, aerospace, information, electronics and other fields, to determine the instrumentation, electrical products, materials, parts, equipment in the low pressure, high temperature, low temperature single or simultaneous action of the environmental adaptability and reliability test, and or at the same time the test piece is energized for the measurement of electrical performance parameters.

Low air pressure test application areas: automotive products, electronic and electrical components, communication products, aviation equipment, PCB, PCBA, instrumentation, household appliances, etc.

Temperature and low pressure test is the test sample in the High Altitude Low Pressure Simulation Test Chamber, and then the air pressure inside the box to reduce the value of the relevant standards, and maintain the test for a specified duration. Its purpose is mainly used to determine the components, equipment or other products in the storage, transportation and use of low pressure environment adaptability. The test applies to the product in the cargo hold of the aircraft air transport, the product used on the plateau and air transport products in the case of aircraft injuries occurred after a rapid drop in pressure. The purpose of the test is to examine the performance of the product in use in a low-pressure environment and the effect of rapid pressure drop on product performance. In the test application is usually distinguished as transport test and operational test environment test, transport environment is usually low temperature accompanied by reduced air pressure as the verification conditions, the operational environment is high / low temperature accompanied by reduced air pressure as the verification conditions.

Temperature / air pressure common effects: air pressure decreases air or insulation material insulation strength is reduced, resulting in electrical discharge, dielectric loss increase, ionization, local overheating caused by material deformation or electrical failure, liquid, gas leakage, airtight failure, sealed container deformation, rupture, motor, engine running instability and other functional or permanent damage.
