IPX7 waterproof test of water immersion test device

What is the waterproof standard of the water immersion test device?NNmTextile Testing Instruments, Testing Equipment Manufacturer
IP (INGRESS PROTECTION) protection level system was drafted by IEC (INTERNATIONAL ELECTROTECHNICAL COMMISSION), which classifies electrical appliances according to their dust-proof and moisture-proof characteristics. The IP protection level is composed of two numbers. The first number indicates the level of protection against dust and intrusion of foreign objects by the electrical appliance (the foreign objects referred to here include tools, human fingers, etc. are not allowed to come into contact with the live parts of the electrical appliance. To avoid electric shock), the second number indicates the airtightness of the electrical appliance against moisture and water immersion, and the larger the number, the higher the protection level. The IPX7 immersion tank test box is an instrument used to test the airtightness and waterproof performance of the product. In the application field, electronic products can achieve level 7 waterproofing, such as mobile phones, tablets, smart bracelets and other products.

Explanation of IPX7 waterproof test level:NNmTextile Testing Instruments, Testing Equipment Manufacturer
Prevent water immersion during immersion, and resist the effects of immersion in water up to 1 meter deep for 30 minutesNNmTextile Testing Instruments, Testing Equipment Manufacturer
Executive Standard:NNmTextile Testing Instruments, Testing Equipment Manufacturer
It can meet international and national standards such as GBT 4208-2017, IEC 60529:2013, ISO 20653-2013, GB7000.1-2015, etc. NNmTextile Testing Instruments, Testing Equipment Manufacturer
The waterproof standard of the immersion test device: It means that it can prevent the impact of short-term immersion in water. After being immersed in water with a specified pressure for a specified period of time, the amount of water entering the shell will not have any impact. Soak the product in the water in the test tank and keep it soaked for 30 minutes. Then take it out of the water and observe whether the phone is soaked in water or fogged. If the product does not have any harmful effects, it is considered qualified. NNmTextile Testing Instruments, Testing Equipment Manufacturer

How to do the IPX7 waterproof test of the watch?NNmTextile Testing Instruments, Testing Equipment Manufacturer
The IPX7 waterproof test of watches actually conducts IP waterproof testing on watch test samples. Through the test, it is determined whether the product meets the IPX7 waterproof level standard requirements. NNmTextile Testing Instruments, Testing Equipment Manufacturer
Clean the casing of the test sample watch, and then put it into the box of the IPX7 waterproof test instrument. The soaking time is 30 minutes. After the test time is completed, take out the test sample for observation and record the results. Although the level 7 waterproof test method is simple, it is not simple at all. NNmTextile Testing Instruments, Testing Equipment Manufacturer

The waterproof test process of the watch:NNmTextile Testing Instruments, Testing Equipment Manufacturer
① Fill the equipment with water to the standard water level. Be careful not to fill the water tank completely. If the water tank is full, the water will overflow when putting the sample. NNmTextile Testing Instruments, Testing Equipment Manufacturer
②Before the test, clean the test sample first to avoid bringing impurities into the water. NNmTextile Testing Instruments, Testing Equipment Manufacturer
③Tie the test sample with nylon rope or steel chain, and then slowly put the test sample into the water. NNmTextile Testing Instruments, Testing Equipment Manufacturer
④ Hang the other end of the rope on the hook of the inner box to facilitate sampling;NNmTextile Testing Instruments, Testing Equipment Manufacturer
⑤The test time is 30 minutes. During the test, you can observe the test conditions in the water tank through the glass. After the test time is up, you can take out the sample by yourself, observe and record the test results;NNmTextile Testing Instruments, Testing Equipment Manufacturer
⑥The test is over; if the water quality is polluted, turbid, or if it is not used for a long time, you can choose to drain the water tank. NNmTextile Testing Instruments, Testing Equipment Manufacturer

How to choose a suitable IPX7 waterproof test machineNNmTextile Testing Instruments, Testing Equipment Manufacturer
First of all, confirm which waterproof level test your product needs, check some parameters or directly contact customer service to inquire whether it is suitable for you. NNmTextile Testing Instruments, Testing Equipment Manufacturer
Secondly, it is the size of the ipx7 waterproof test device. The quantity you need to test, whether it is a small amount or a large amount, its regular dimensions are: 600*600*600mm, 800*800*800mm, 1000*1000*1000mm, 1200*1200 *1200mm and so on. The cabinet can be selected according to the amount of daily testing, of course, it can also be customized according to user needs. NNmTextile Testing Instruments, Testing Equipment Manufacturer
Another point is that the ipx7 waterproof test device has two different functions, namely electric lift type and electric traverse. Is the product you are testing a small sample or a large sample? For testing large samples, we can provide customers with electric functions, so that large samples can be easily placed and taken out. On the contrary, for small samples, you can choose conventional instruments. NNmTextile Testing Instruments, Testing Equipment Manufacturer
