High Altitude Low Pressure Simulation Test Chamber meets MIL-STD-810 and RTCA DO-160 standards
High Altitude Low Pressure Simulation Test Chamber meets the criteria
Meets MIL-STD-810 and RTCA DO-160 standards
High Altitude Low Pressure Simulation Test Chamber Application scope:
It is suitable for evaluating the ability of transport packages and unpressurized cargo in pressurized cabins and non-pressurized aircraft flying at altitudes not exceeding 3500 meters during air transportation, to withstand the effects of low pressure and to protect the internal contents of the package. Low-pressure test can be carried out for the ground transport packages and unpressurized cargo at higher altitudes.
High Altitude Low Pressure Simulation Test Chamber Principle:
The test sample is placed in the air pressure test chamber, and then the air pressure in the test chamber is reduced to the air pressure equivalent to the height of 3500 meters, keep the air pressure for a predetermined time, make it return to normal pressure.
If necessary, the temperature can also be controlled at the same height during this period.
High Altitude Low Pressure Simulation Test Chamber Test equipment:
The air pressure chamber shall have sufficient space to accommodate the test sample and be capable of air pressure and temperature control.
High Altitude Low Pressure Simulation Test Chamber Test steps:
4. Place the test sample in the air pressure test box, reduce the air pressure to 650×105m Pa(±5%) at the rate of no more than 150×105m Pa/min, and maintain the air pressure within a predetermined time. The retention time can be selected within 2h, 4h, 8h, 16h.
5. At the supercharging rate of no more than 150×105m Pa/min, fill the dry air conforming to the laboratory temperature to restore it to the initial state
6. After the test, check the damage of the package and contents according to the relevant standards, and analyze the test results.
