Metal waterproof joint sealing performance judgment standard and machine plate caliber size

Metal waterproof joints, as the name implies, can be applied to water-borne environments to provide a safe and reliable waterproof connection. For example: LED street lights, lighthouses, cruise ships, instrumentation, industrial equipment, sprinklers, etc., all need to use waterproof joints.
  At present, there are many brands and types of waterproof joints on the market, but in the true sense, it has excellent sealing performance, safe and reliable waterproof joints, that is, the waterproof joint products are put into 10 meters deep water for long-term work; In the deep water, the damage test for 12 hours, the product can still maintain good performance.
Metal waterproof joint sealing performance judgment standard
At present, the main criterion for the waterproof performance of waterproof joints is based on the IP waterproof rating standard. Look at the waterproof performance of waterproof joints, mainly look at the two digits XX behind IPXX, the first digit is from 0 to 6, the highest grade is 6; the second digit is from 0 to 8, the highest grade is 8; therefore waterproof joint The highest waterproof rating is IP68.
Degree of protection against solids (first X)
0: no protection
1 : Prevent the intrusion of solids above 50mm, which is equivalent to the length of one hand;
2: Prevent 12.5mm solid intrusion; equivalent to the length of one finger;
3: Prevent 2.5mm from entering the intrusion. Equivalent to a line or tool;
4: Prevent the entry of solids larger than 1.0mm, which is equivalent to a line or stripping line;
5: Prevent dust from entering fully and causing damage;
6 : Completely prevent dust from entering
Water protection rating (represented by the second X)
0 : not waterproof
1 : Prevent water droplets
2: When the housing is tilted to 15 degrees, the drop of water drops into the housing has no effect
3: Water or rain has no effect from the 60 degree corner to the outer casing
4: The liquid is splashed from any direction to the outer casing without damage
5: Rinse with water without any damage
6 : Prevents strong spray water and can be used in the environment inside the cabin
7 : Resistant to water in a short time
8: Continuous flooding under a certain pressure
In particular, customers are reminded that the protection level of waterproof joints has reached IP68, but the opening of the machine board is more important, such as the opening of the machine plate is too large.
