Test method for IP67 of smart Watch

With the rapid development of modern science and technology, smart watches can be seen everywhere in most sports lovers' lives. It is also widely sold in the market. Now the manufacturers of smart watches attach great importance to the protection function of products, which is an important performance of convenient use and durable performance. In order to make consumers have a better use experience, the product has done the protection test, which can have a greater advantage in the market, and can be recognized by more consumers in the long term.

Why does smart watch need IP67 test?

The IP67 test of products is a high level of waterproof grade standard. It is inevitable that smart watches will come into contact with water during our use. Therefore, the waterproof grade test of products is very necessary and meets the needs of consumers. IP67 test is a test that many enterprises need to do now. The tested products have more competitive advantages in the market, It is beneficial to the development of enterprises.

The test equipment, test conditions and test time of IP67 waterproof grade should be approved by both the supplier and the demander, and its severity is naturally higher than any grade below. For example, the IP68 waterproof test of bulgin's waterproof connector is: ensure to work for 2 weeks in the water depth of 10 meters without water entering; After being put into 100 meters water depth and tested for 12 hours, the good performance of the product can still be maintained.

One of the definitions of IP grade (dustproof and waterproof): ip67ip is the abbreviation of ingress protection. IP grade is the protection grade of electrical equipment shell against foreign matter invasion, such as explosion-proof electrical appliances, waterproof and dustproof electrical appliances. The source is IEC 60529, which was also adopted as the American national standard in 2004. The format of IP grade is ipxx, in which XX is two Arabic numerals. The first marking digit indicates the protection grade of contact and foreign objects, and the second marking digit indicates the waterproof protection grade. The specific protection grade can refer to the following table. IP is the international code used to identify the level of protection, IP level is composed of two numbers, the first number represents dust; The second number is waterproof, and the larger the number, the better the degree of protection.

IP67 test method of smart Watch

The test equipment, test conditions and test time of IP67 waterproof grade should be approved by both the supplier and the demander, and its severity is naturally higher than any grade below. For example, the IP67 waterproof test of bulgin's waterproof connector is: ensure to work for 2 weeks in the water depth of 10 meters without water entering; After being put into 100 meters water depth and tested for 12 hours, the good performance of the product can still be maintained.

IP6X

The sample is assembled in the joint and put into the dustproof box. Talcum powder is used in the test. The test time is 8 hours, and there is no dust invasion

IPX7

Assemble the sample and the joint into the test fixture, and inject clean water into the test fixture from the external air socket. The water surface is at least 20 mm higher than the top of the test piece, and there is a certain space above the water surface. Insert the air inlet pipe into the air inlet plug. In addition, observe the water leakage of the fixture, connect the rubber pipe plug with a 100 mm short pipe, and apply 0.10 MPa air pressure from the air inlet pipe for 30 minutes, Observe whether there are leakage water drops from the short pipe.

Note: there is no air leakage in the joint parts, the test pieces are breathable, and the assembled test tooling is free of air leakage. There is no leakage water drop phenomenon.

The purpose of the test standard is as follows:

Specified enclosure protection level for specified electrical equipment load:

Prevent the human body from approaching the dangerous parts in the shell;

Prevent solid foreign matters from entering the equipment in the shell;

To prevent harmful effects on the equipment due to water entering the shell.

Significance of IP67 test for smart Watch

After IP testing, electronic products have more competitive advantages in the market. When products enter the market for sale, they can bring more profits to enterprises. Enterprises have a certain understanding of the dust and waterproof test of products, which can help our products better open the door of the international market.

In the past ten years, we have been focusing on the R & D, production and sales of air tightness testing equipment, with stable performance and high precision. We can customize the testing tooling on demand! The products sell well at home and abroad, and can provide all kinds of waterproof testing, sealing testing, leakage testing, IP waterproof grade testing scheme for free.
