What does the IP waterproof and dustproof rating mean?

The protection level is represented by IP followed by two numbers, which indicate the level of protection. The larger the number, the higher the protection level of the product.
The first number represents the level of dust prevention and foreign object intrusion prevention of the product.
The second number represents the degree of sealing of the product against moisture and water intrusion.

There are 6 levels of dust protection, which is an important indicator of safety protection and adopts the IP level standard recommended by the International Electrotechnical Commission (IEC). In the level standard, the first digit represents the protection level against dust, which is represented by 0-6. Different dust prevention abilities have different levels

• 0: No protection
• 1: Prevent large solids from invading
• 2: Prevent the intrusion of medium-sized solids
• 3: Prevent small solids from entering and invading
• 4: Prevent solid objects larger than 1mm from entering
• 5: Prevent the accumulation of harmful dust
• 6: Completely prevent dust from entering

There are 8 protection levels for IP waterproofing, using the recommended IP rating standards by the International Electrotechnical Commission (IEC). In the standard, the second digit represents the level of protection against liquids. Represented by 0-8, the larger the number, the higher the waterproof level.

• 0: No protection
• 1: Water droplets entering the shell have no effect
• 2: When the shell is tilted to 15 degrees, water droplets entering the shell have no effect
• 3: Water or rainwater from a 60 degree corner has no impact on the shell
• 4: The liquid splashed onto the shell from any direction does not cause any harm or impact
• 5: Rinse with water without any harm
• 6: Can be used in the cabin environment to prevent large waves from invading.
• 7: Can withstand immersion in water for a short period of time (1m)
• 8: Immerse in water for a long time under a certain pressure

During the IP level testing process, the product does not need to be powered on, and the electrical parts inside the shell can be removed. It is also possible to leave the shell blank for testing. After the dust and waterproof tests, open the shell and visually observe whether there is dust and water droplets entering the inside of the shell. If not, it is judged to have passed the test; (CNAS and CMA accredited laboratory testing is required).
