How to choose the size and specifications of sand and dust test chamber
From: BONAD  Date: 2024-03-26 17:13:48

Sand and dust test chambers are also called dust-proof test chambers, dust-resistant test equipment, dust boxes, etc. However, their specifications are determined by the customers' needs to test the products, and the functionality will also vary depending on the solutions. .


How to choose the size and specifications of the sand and dust test chamber?

When choosing the specifications of the sand and dust test chamber, generally first consider the size of the sample to be tested. According to the principle that the product occupies no more than one-third of the space, the inner box to be tested should be 2 times larger than the volume of the product.
Because the size of the product to be tested will affect the test results. If the product is too large and the box is too small, it will affect the speed of dust blowing. The lack of air circulation will also cause dust to easily agglomerate. Therefore, in order to avoid incorrect test results due to changes in air flow, the size of the sand and dust test chamber should generally be 2-5 times that of the sample.
