The difference between the dust-proof test chamber and the rain test chamber

The dust-proof test chamber is actually to simulate the climate environment with sand and dust to carry out the dust-proof test and wind-sand test on the tested samples, and the rain test chamber is just the opposite. It is a box that tests the test box through the humid environment created in the box and then converts it into raindrops. It is a chamber that tests the test chamber through the humid environment created in the chamber and then converts it into raindrops. These two kinds of environmental test chambers have a wide range of uses in military, aerospace, and industry, and many industries have taken it as a major development project, and environmental test chambers are also recognized as a future development trend. The dust-proof test chamber and the rain test chamber are cold and hot, wet and dry, and it seems that there is no difference between the two test chambers, both of which simulate the outdoor environment. However, there is an inseparable similarity, the first two chambers that appeared as an environmental test chamber. They have reached heights that they cannot be surpassed by others. The working chamber of the dust-proof test chamber is generally smaller than 800L, because this is caused by their own principles. According to the requirements in the national standard GB/T4208-2008 shell protection level (IP code), the bottom area of the dust-proof chamber is 2 times the sample volume, and the chamber volume is 4 times the sample volume; The working chamber of the rain test chamber is much smaller. The dust-proof test chambers are generally used in industry, while the rain test chambers are widely used in the military. They also have in common that they all report the same time when a failure occurs, and the time to deal with the failure is extremely fast. The dust-proof test chambers and the rain test chambers will play an increasingly important role as representatives of environmental test chambers.
