When the sand and dust test chamber is tested, the requirements of wind speed are required:
●One is the blowing dust test,
●The other is the dust test,
●There is also a sand blowing test (MIL-STD-810G 510 Blowing Dust And Sand Test Machine)
The requirements for the wind speed of the sand and dust test chamber are as long as it is ensured that the dispersing test pieces inside the test chamber are not stained with dust.
●Dust blowing normally: the minimum wind speed in the test should be >1.5m/s.
●The simulation is the sand and dust in the desert. Because of its heavy weight, the sand test wind speed is required to be between 18m/s-29m/s.(MIL-STD-810G 510 Blowing Dust And Sand Test Machine)
●The distance between the sand injection inlet and the test piece is generally 3m.
●In the wind speed range required by this test, high wind speed is rare, such as gust of 29m/s, but it is rarely used in the test.
●For the regulation of wind force in the dust suppression experiment, if the smoke and dust do not touch the dispersed specimen in the sand and dust aging test chamber, the wind force can be lower than 0.2m/s.
●For example, to simulate the sandstorm in the desert, because of its large net weight, the wind force should be > 8.9m/s. Of course, if that is the case, the wind force should be higher.
