How to use the immersion tank waterproof test device to do ipx7 waterproof test

What is the waterproof standard of the immersion tank waterproof test device:
The 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 electrical dustproof and foreign object intrusion prevention (the foreign objects referred to here, including tools, human fingers, etc., cannot touch 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 waterproof test device is an instrument used to test the airtightness and waterproof performance of the product. Application fields Electronic products can reach level 7 waterproof, such as: mobile phones, tablets, smart bracelets and other products.

IPX7 waterproof test level description:
Prevent water immersion when submerged in water, and resist 30 minutes of immersion in water up to 1 meter deep

Executive standard:
It can meet international and national standards such as GBT 4208-2017, IEC 60529:2013, ISO 20653-2013, and GB7000.1-2015.

The waterproof standard of the immersion tank waterproof test device:
 it means that it is protected from the impact of short-term immersion, and the water inflow of the shell will not be affected after being immersed in water with a specified pressure for a specified period of time. Put the product into the water of the test tank and soak it for 30 minutes. Then take it out of the water and observe whether the mobile phone has water or mist. If the product has no harmful effects, it is qualified.

Experimental conditions of immersion tank waterproof test device:
1. The low point of the shell with a height less than 850mm should be 1000mm below the water surface;
2. The high point of the shell with a height equal to or greater than 850mm should be 150mm lower than the water surface;
3. The test duration is 30 minutes;
4. The difference between the water temperature and the sample temperature is not more than 5 degrees Celsius.

Features of the immersion tank waterproof test device:
1. Outer chamber material: All are made of high-quality (t=1.2mm) A3 steel plate CNC machine tool, and the surface of the shell is sprayed with plastic, which is more smooth and beautiful;

2. Inner chamber material: imported high-grade stainless steel (SUS304)
3. Insulation material: rigid polyurethane foam + glass fiber
4. Door insulation material: glass fiber cotton
5. Rotary table: the table is PVC hard board (corrosion resistance)
6. The parts in contact with water are made of stainless steel or copper
7. Automatic water level lifting function.

Experimental conditions of immersion tank waterproof test device:
1. The low point of the shell with a height less than 850mm should be 1000mm below the water surface;
2. The high point of the shell with a height equal to or greater than 850mm should be 150mm lower than the water surface;
3. The test duration is 30 minutes;
4. The difference between the water temperature and the sample temperature is not more than 5K. If the sample needs to be tested while it is charged and (or) running, the relevant product standards can make additional regulations on this requirement.

How to do the IPX7 waterproof test of the watch?
The IPX7 waterproof test of the watch is actually an IP waterproof test for the watch sample. After passing the test, it is judged whether the product meets the requirements of the ipX7 waterproof level standard.
Clean the shell of the test sample watch, and then put it into the lower 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 result. Although the level 7 waterproof test method is simple, it is not simple at all.

The waterproof test process of the watch:
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.
②Before the test, clean the test sample first to avoid bringing impurities into the water.
③Tie the test sample with nylon rope or steel chain, and then slowly put the test sample into the water.
④ Hang the other end of the rope on the hook of the inner box to facilitate sampling;
⑤ The test time is 30 minutes. During the test period, you can observe the test situation 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;
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.

How to choose the right immersion tank waterproof test device:
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.
Secondly, it is the size of the immersion tank waterproof test device
. The quantity you need to test, whether it is a small amount or a large amount, its conventional 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.
Another point is that the immersion tank 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.

JL-X waterproof test machine is according to IEC60529:1989 +A1:1999 +A2：2013 《Degrees of protection provided by enclosures(IP Code)》, IEC60598, IEC60335 and IEC 60034-5, GB/T-2423.2, GB4208, GB7000.1. The JL-X includes the following test grades: IPX1, IPX2, IPX3, IPX4, IPX5, IPX6, IPX7 and IPX8 (Refer to page 51 of IEC60529). It is widely used in the authentication test organization for the products such as electrical & electronic products, LED luminaires as well as in the relevant quality control department for the waterproof detection of the enclosures protection grades.
