Housing Protection Level (IP Code) is a classification of products based on their characteristics of dust prevention, foreign object intrusion prevention, waterproofing, and moisture resistance. The foreign objects referred to here, including tools, human fingers, etc., should not come into contact with the live parts inside the lamp to avoid electric shock. It is generally composed of two numbers, with the first number indicating the level of dust prevention and foreign object intrusion prevention of the product; The second number represents the airtightness of the product against moisture and water intrusion. The larger the number, the higher the level of protection it has. For example, the degree of protection provided by the enclosure (IP code) is shown as IPXX,
Test contentDust level (first X represents)
0: No protection
1: Prevent large solid intrusion
2: Prevent medium solid intrusion
3: Prevent small solid intrusion
4: Prevent solid objects larger than 1mm from entering
5: Prevent harmful dust accumulation
6: Completely prevent dust entry
Waterproof level (second X represents)
0: No protection
1: Water droplets dripping into the casing have no effect
2: When the casing is tilted to 15 degrees, Water droplets dripping into the shell have no effect
3: Water or rainwater from a 60 degree corner has no effect on the shell
4: Liquid splashed from any direction onto the shell has no harmful effect
5: Flushing with water does not cause any harm
6: Can be used in the environment inside the cabin
7: Can withstand immersion in water for a short time (1m)
8: Immersion for a long time under a certain pressure
The standards for the shell protection level (IP code) are:
1) By IEC International Protection and Waterproof Testing Standards drafted by the International Electrotechnical Commission: International Electrotechnical Commission Standard IEC 529-598; 2) GB 700-86; 3) GB 4208, etc Testing Standard Product Name Testing Project Testing Standard Shell Protection Level (IP Code) IP Level GB T 4208-2017 Protection Level of Rotating Electrical Machines Overall Structure IP Level GB T 4942.1-2006
