The rain tester, also known as rain test chamber, can simulate different degrees of rain of different intensities, such as light rain, moderate rain, heavy rain, torrential rain, etc., in order to test the waterproof performance of products under various rainfall conditions. This helps to assess whether the product can work properly in harsh rain environments and avoid rainwater infiltration leading to equipment damage or malfunction.
When it comes to the rain test machine, many people may know that its common waterproof grade is divided into a total of ipx1 to ipx9k a total of nine, but many people may not know much about its respective technical parameters, such as the difference between IPX7 and IPX9K what is it? The following will introduce the IPX7 and IPX9K waterproof grade test in the rain test machine is two different test standards, their main difference lies in the test conditions and test methods:
(1) IPX7 waterproof rating
1. The product is immersed in water at a specified pressure, the depth of water is usually at least 1 meter.
2. The distance from the bottom of the sample to the water surface is at least 1 meter, while the distance from the top of the sample to the water surface is at least 0.15 meters.
3. The product needs to be continuously immersed in water for 30 minutes under the above conditions.
4. Although the water pressure is not specified, but usually need to ensure that the water can completely cover the product.
(2) IPX9K waterproof rating
1. Use high temperature (usually up to 80 ° C) and high pressure (up to 100 bar) of water to spray the product.
2. The diameter of the nozzle is about 6.3mm and the nozzle is 100-150mm away from the product.
3. The product is sprayed from all angles and directions for 30 seconds per position, for a total of 4 positions.
4. Simulate the waterproof performance under severe conditions and evaluate the ability of the product to withstand high pressure and high temperature environments.
The above introduction about the difference between IPX7 and IPX9K rain test machine IPX7 and IPX9K is shared here first.
