Temperature Altitude Chamber

Name: Temperature Altitude Chamber
Brand: Xi'an LIB Environmental Simulation Industry

LIB temperature altitude chamber can be used to simulate the environment of low pressure ranging from atmospheric pressure(101.kpa) to 0.5kPa at high altitude, mainly for testing the performance and reliability of equipment in these extreme conditions.

In a low pressure environment, the atmospheric pressure is reduced because the air density is reduced. In turn, it affects the mechanical pressure, heat dissipation efficiency, electrical performance, sealing and so on.

Model: A-1000

Standard: IEC 60068, IEC 60749, MIL-STD-202F

Temperature Altitude Chamber Features and Benefits

1. Accurately simulate the air pressure environment from sea level to thousands of meters high, the range of air pressure changes can be adjusted arbitrarily, and can be combined with high and low temperatures and other conditions.

2. The control system is highly automated, and can accurately adjust and control temperature, pressure and other parameters according to the preset program.

3. The product is tested under extreme low pressure conditions, and the ability and reliability of its work in high altitude, high altitude and other environments are accurately evaluated.

4. Widely used in aerospace, electronics, automotive and other fields to meet the strict standards and regulatory requirements of product environment adaptability in various industries.

Low Pressure Test Procedure

1. Preparation before test :

Determine test samples and test standards.

Calibrate and prepare test equipment.

Record the initial status and parameters.

2. Low Pressure storage test :

Place the device in a low pressure environment to simulate high altitude storage conditions.

Maintain the specified time to observe the mechanical and physical changes of the equipment.

3. Low pressure working test :

Start the equipment under low pressure conditions to test its performance.

Record the working status and data of the equipment in low pressure environment.

4. Rapid decompression test :

Simulate the rapid entry of equipment from a pressurized environment into a low pressure environment to test the emergency response of the equipment.

Hold the specified time to observe the transient response and damage of the equipment.

5. Explosion decompression test :

Simulates extremely rapid pressure drops, similar to decompression conditions after an explosion.

Perform pressure changes over a short period of time to observe structural damage and functional failure of the equipment.
