The waterproof rating IP is an evaluation standard used to measure the water resistance of electronic devices. Where "IP" stands for Ingress Protection, which translates to Protection Rating, the IP rating usually consists of two numbers, the first number refers to the level of protection against solid particles and the second number refers to the level of protection against water. For example, an IP68 waterproof rating indicates that the device will remain undamaged when subjected to dust and fully submerged in water at a static depth of more than 1 meter for 30 minutes.
The waterproof rating IP is one of the most important features of modern electronic devices, especially in outdoor and harsh environments, where waterproof protection can significantly increase the service life of the device and reduce repair and replacement costs. Therefore, it is critical for those who manufacture, sell and use waterproof equipment to know and understand the IP rating.
While the waterproof rating IP is often used to characterize the waterproofing of electronic devices, it should be noted that the IP rating is only a theoretical assessment. In practice, the water resistance of many electronic devices may deteriorate significantly after a period of use. Therefore, for individuals or companies using waterproof devices, usual maintenance and repair is also essential work, only then can truly play the benefits of IP rating.
