High Altitude Low Pressure Test Chamber for Cosmetic Sample Testing
**Application:**
As you know, the purpose of this test is to simulate the environmental conditions inside an aircraft cargo hold during the transportation of cosmetics at high altitudes. This includes the period from takeoff, as the plane leaves the ground, to when it enters the stratosphere for long-distance cruising after a steady climb. During this process, two key factors need to be considered: the minimum cold temperature experienced during cruising in the stratosphere and the rate of temperature change while climbing after takeoff and reaching a stable altitude.
Due to the limitations of our professional knowledge in this specific field, we are unable to determine how fast the cargo plane climbs vertically per minute. Therefore, we also cannot precisely calculate how quickly the internal temperature changes. However, as experts in scientific research for such testing, we are confident that you can find these answers. If so, it would be much better for both of us to evaluate the feasibility of the above-mentioned proposal.
