Nowadays, our lives are inseparable from electronic products, especially in the rainy season and bad weather season, the waterproof performance of electronic products is particularly important. So, how are the IP waterproof grades of electronic products divided? Below, we will explain it in detail for you.
Definition of IP waterproof rating
The IP (Ingress Protection) waterproof rating is used to measure the ability of electronic products to resist external moisture intrusion. The IP rating consists of two numbers, the first number indicates the dustproof level, and the second number indicates the waterproof level. For example, IP54 means the dustproof level is level 5 and the waterproof level is level 4.
IP waterproof level classification
The IP waterproof level is divided into 10 levels from 0 to 9. The larger the number, the higher the waterproof level. The details are as follows:
- IPX0: No waterproof level, the product does not have waterproof function.
- IPX1: Drip-proof type I, vertically falling water drops have no harmful effects.
- IPX2: Drip-proof type II, water drops falling within 15° from the vertical direction have no harmful effects.
- IPX3: Rainproof type, water-proof, no harmful effects from rain within 60° from the vertical direction, basically can prevent light rain scale precipitation.
- IPX4: Splash-proof type, splash-proof, no harmful effects from water splashing in any direction, can prevent light to moderate rain scale precipitation.
- IPX5: Jet-proof type, no harmful effects from direct water spraying in any direction, can prevent moderate to heavy rain scale precipitation.
- IPX6: Wave-proof type, no harmful effects from water intrusion from violent waves or waves, can prevent heavy rain to torrential rain scale precipitation.
- IPX7: Prevent short-term immersion. After being immersed in water of specified pressure for a specified time, the amount of water entering the shell will not reach a harmful level, which can prevent short-term immersion.
- IPX8: Prevent continuous immersion. After continuous immersion, the amount of water entering the shell will not reach a harmful level, and it can work in shallow water.
- IPX9: Prevent high-temperature and high-pressure water spray. Spraying high-temperature and high-pressure water in all directions of the shell has no effect. It can work in certain harsh environments and a certain degree of underwater.
Application of IP waterproof rating
IP waterproof rating is not only used in electronic products, but also widely used in medical equipment, industrial equipment, outdoor equipment and other fields. Among electronic products, mobile devices such as mobile phones, tablets, and laptops have higher requirements for waterproof performance, while household appliances, medical equipment and other equipment have more stringent requirements for waterproof rating.
How to judge the authenticity of IP waterproof rating
When purchasing electronic products, how to judge the authenticity of its IP waterproof rating? First, you can check the IP rating in the product manual or specification sheet; second, you can check whether the manufacturer has obtained relevant waterproof certification, such as GBT 4208-2017 Enclosure Protection Level (IP Code), etc.; finally, you can understand whether the use environment and usage of the product meet the requirements of the waterproof level.
How to use electronic products with IP waterproof rating correctly
- Avoid using electronic products in humid environments, such as bathrooms, kitchens, etc.
- When using electronic products in rainy days or bad weather, try to keep the products dry and avoid long-term exposure to water.
- Do not store electronic products in places that are too humid, such as basements, storage rooms, etc.
- If the product is marked with an IP waterproof rating, it should be used and maintained correctly according to the rating requirements.
Conclusion
Understanding and correctly using the IP waterproof rating is a very important skill in our daily life. By understanding the waterproof performance and application areas of different electronic products, we can better protect our equipment and extend its service life. At the same time, we also need to pay attention to the authenticity and correct use of the product to avoid unnecessary losses due to incorrect operation.
