There has been an interesting news on the Internet recently. It is said that a man in Hangzhou, after the release of Apple’s new machine, bought the iPhoneXS Max with great interest, and this iPhoneXSMax has reached the IP68 level of waterproof and dustproof, which is the highest level of dustproof and waterproof mobile phone in the mobile phone market. Once, the younger brother exercised as usual. After the exercise, he found that the phone was dirty, the phone was dirty, the waterproof phone was clean, and then the phone was accidentally dropped. Seeing this, friends will definitely have such a question: “Why do you say waterproof?”

IP (INGRESS PROTECTION) protection grade system is drafted by IEC (INTERNATIONAL ELECTROTECHNICAL COMMISSION), which classifies electrical appliances according to their characteristics of dust and moisture prevention. IP protection level is composed of two numbers. The first number represents the level of dust-proof and intrusion-proof of electrical appliances (the objects referred to here contain tools, human fingers, etc. can not touch the live part of electrical appliances in order to avoid electric shock). The second number represents the sealing degree of moisture-proof and water-proof immersion of electrical appliances. The larger the number is, the larger the table is.
