The IP (Ingress Protection) protection level system was drafted by the IEC (International Electrotechnical Commission) and is graded according to dust and waterproof characteristics. IP protection level is made up of two numbers, the first number indicates the level of dustproofness, preventing the entry of foreign objects, the highest level is 6; the second number indicates the degree of waterproof immersion, the highest level is 8. The IP protection level is composed of two numbers, the first number indicates the level of protection against dust, preventing the entry of foreign objects, and the highest level is 6; the second number indicates the degree of waterproof and immersion of the airtightness, and the highest level is 8.

Code | Description of protection | Code | Description of protection |
0 | Unprotected | 0 | Unprotected |
1 | Prevents entry of solid foreign matter with a diameter greater than 50mm | 1 | Protects against vertical drips |
2 | Prevents entry of solid foreign matter with a diameter greater than 12mm. | 2 | Protected against water drips when tilted at 15 degrees |
3 | Prevents entry of foreign matter with a diameter greater than 2.5mm. | 3 | Protected against water drops even when tilted at 60 degrees |
4 | Prevents entry of foreign matter with a diameter greater than 1.0mm. | 4 | Protected against splashing water in all directions |
5 | Protected against foreign matter and dust | 5 | Protected against low-pressure spraying of water in all directions for at least 3 minutes. |
6 | Protected against foreign matter and dust | 6 | Protected against strong spray like waves for at least 3 minutes. |
7 | Protected against water immersion for 30 minutes in water up to 1 meter deep. | ||
8 | Protected against water immersion in water more than 1 meter deep |
