Waterproof joint judgment standard

Author:

At present, the main evaluation standard for the waterproof performance of waterproof connectors is based on the IP waterproof rating standard. Looking at the waterproof performance of the waterproof joint, it mainly depends on the two digits XX behind IPXX, the first x is from 0 to 6, and the highest grade is 6; The second digit is from 0 to 8, and the highest grade is 8. Therefore, the highest waterproof grade of the waterproof joint is IP68.
Solid protection class
0: No protection
1: Prevent the intrusion of solids above 50mm,;
2: Prevent the intrusion of 12.5mm solids;
3: Prevent 2.5mm from entering;
4: to prevent objects larger than 1.0mm solid;
5: prevent dust from fully entering and causing damage;
6: completely prevent dust from entering
Degree of protection of water
0: not waterproof
1: prevent water droplets
2: When the shell is tilted to 15 degrees, water droplets dripping into the shell have no effect
3: Water or rain from the 60 degree corner to the shell has no effect
4: liquid from any direction spilled into the shell no harm effect
5: water rinse without any harm
6: to prevent strong jet water, can be used in the cabin of the environment
7: can be in a short period of time resistant to immersion
8: Continuous immersion under certain pressure
In particular, the test equipment, test conditions and test time of the highest grade IP68 of the waterproof joint are agreed upon by the supply and demand (buyer and seller), and its severity is naturally much higher than the protection level below it. For example, the IP68 waterproof test of Bulgin's waterproof joint is to ensure that it works for 2 weeks at a water depth of 10 meters without entering water. Put it in 100 meters of water and test it for 12 hours, which can still maintain the good performance of the product.
