What are the factors determining the accuracy of the rain test chamber test?
Rainproof waterproof test box is of great help in practical applications, especially in automotive lighting applications. So, do you know the factors that influence the rain test machine when doing the experiment? Let's take a look at the Shanghai Bao test together: 1. Factors for product placement When we are doing the test, the length of the test directly affects the rationality of the test results. If the test time is too long, it will not meet the natural rainfall. If it is too short, the rainwater will not enter the test product, and the effect of the test will not be achieved. In addition, in the case of natural rainfall, since the direction of each rain cannot be the same, this is the case where the surface of the test product is exposed to rain, so we put the test product in normal use during the test. 2, the temperature factor of water Larger rainfall intensity generally occurs in the summer with higher temperature, but due to the rain, the rain can adjust the temperature, so the temperature of the rainwater falling to the ground will not be too high. When testing according to the standard test conditions, the temperature of the water can be It is not necessary to control, but the temperature of the water should be as close as possible to the temperature of the tested product to reduce the possibility of condensed water inside the tested product. Therefore, the temperature of the test water should be 15 °C ± 10 °C. 3. Water pressure factors The pressure of the rain test chamber is supplied by tap water. Sometimes the pressure is high, sometimes the pressure is small, and the fluctuation is very large. It can not meet the water pressure of the supplied product according to the standard. Therefore, we specially designed the water pressure regulator. Not only does the energy source continuously supply water, but it also maintains the required water pressure required for the test on a regular basis to ensure that the test is carried out under normal water pressure. In short, the test parameters of the lamp enclosure protection level are based on meteorological data for many years, and simulate the harsher natural conditions as much as possible. Therefore, it is necessary to properly consider the acceleration and repeatability of the test to evaluate the product.
