Characteristics of IPX7 Immersion tank Waterproof test Device

IP (Ingress Protection) protection grade system is 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 represents the level of dust prevention and intrusion prevention of electrical appliances (the external objects, including tools, human fingers, etc., cannot touch the live parts of electrical appliances to avoid electric shock). The second number represents the degree of tightness of electrical appliances against moisture and water immersion. The larger the number, the higher the protection level.

IPX7 Immersion tank Waterproof test Device is an instrument used to test the airtightness and waterproof performance of products. In the application field, electronic products can reach grade 7 waterproof, such as mobile phones, tablets, smart bracelets and other products.

IPX7 waterproof grade description:
Prevent water immersion during immersion, and prevent 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 IPX7 Immersion tank Waterproof test Device: it means to prevent the impact of short time immersion, and the water inflow of the shell after immersion in the water at the specified pressure will not have any impact after the specified time. Put the product into the water of the test tank and soak it for 30min. Then take it out of the water and observe whether there is water or mist on the mobile phone. The product is qualified if it has no harmful effects.

Test conditions of IPX7 Immersion tank Waterproof test Device:
1. The low point of the shell with height less than 850mm shall be 1000mm lower than the water surface;
2. The high point of the shell with a height equal to or greater than 850 mm shall be 150 mm below the water surface;
3. Test duration: 30min;
4. The temperature difference between the water temperature and the sample shall not be greater than 5 ℃.

Characteristics of IPX7 Immersion tank Waterproof test Device
1. The inner layer of the ipx7 Immersion tank Waterproof test Device is made of 304 stainless steel plate by overall sub-arc welding to ensure that it will not rust and seep water after long-term use;
2. In the middle of the double layer, 40 square steel pipes are used as rib plates to keep the inner box from deformation;
3. The surface layer is welded with hairline stainless steel plate, and the black mirror steel plate edge banding is selected. The surface is free of spot welding, which is unique overall.
4. The water valve is located on the upper back of the water tank under the construction of the water inlet and outlet pipeline.
5. The window is made of 15mm tempered laminated glass, which can clearly observe the test condition of the test object.
6. The stainless steel plate support frame is equipped with a weight universal wheel and a foot cup, which is convenient to move and fix.
7. The stainless steel ruler displays the information water level.

Is there any requirement for water pressure of waterproof test equipment?
There are a wide variety of waterproof test equipment, and their water pressure is not a fixed number, which can be converted. For example, the pressure of IPX56 deluge test box is not required in the international standard, that is, it is not fixed. For example, the water pressure of IPX7 deluge test chamber is based on the water depth requirement. For example, if the water depth is 1 meter, it is the pressure of 10kpa. For example, the water pressure of ipx9 high temperature and high pressure deluge test box can reach 8000kp-10000kp. Through the above example, I believe you have a number in mind.

How long is the waterproof test of the waterproof test system?
The appropriate time for the waterproof test of the product is mainly determined according to the national and international standard test requirements or the user’s requirements for the test time of the product. Some people think that the longer the test time is, the better. In fact, it is not. The test time of the waterproof test device can be done for 24 hours or 48 hours, but it is not recommended that the time is too long. If the time is too long, it will cause some damage to the product.

For example, the test time of IPX7 immersion test is 30 minutes, and IPX8 immersion machine wrote in GB/T4208-2017 Enclosure Protection Class (IP Code): it is manufactured by the manufacturer through negotiation with the user, which has no standard time specification. So how long is the best time? It’s really hard to say. The test time will be different for different levels.

How to judge the IPx7 Immersion tank Waterproof test Device as qualified
The ipx7 Immersion tank Waterproof test Device is the usual immersion test chamber, which is applicable to the IPX7 waterproof grade test of the product.

Judgment method: immerse the electronic product in the IPX7 Immersion tank Waterproof test Device with a water depth of 1-1.2 meters for 30 minutes, and the electronic product is qualified if it has no harmful effects.

Daily methods to prolong the service life of Immersion tank Waterproof test Device:
1. Before the test, the water tank of the test sample must be filled before the test;
2. Keep the inner tank and water tank of the waterproof testing machine clean, and clean the water stains when not in use; Diligent to change water once a week;
3. If the filter element inside the filter becomes black, replace it in time;
4. If the needle on the swing tube is deformed or blocked, replace it in time;
5. The bearing capacity of the standard turntable is ≤ 50kg. Do not overload.
6. According to the date of the calibration certificate, the local third-party organization shall be found in time for calibration; Once a year.
7. The waterproof test system should be placed in a ventilated environment as far as possible to avoid the impact of humid climate on the chassis.
8. The service life of the waterproof test system is also related to the frequency of use, so these are very routine in daily life, but these small details can also improve the service life of the equipment.

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).
