Igeekphone October 19 news, this morning, Weibo certified as Redmi product manager Wu Hao released a micro blog, saying that Redmi Note 13 Pro+ passed the IP69 test.
“Pre-market research and development only allowed me to talk about IP68, this IP69 test passed, and the Note 13 Pro+ has further protection against high temperature and high pressure water spraying,” it said on Weibo.
According to the test report posted by the blogger, the Redmi Note 13 Pro+ prototype passed the IPX9 waterproof test at 24.7℃, 57.0% R.H, 86kPa-106kPa detection environment.
According to public information, the full name of IP Protection grade is International Protection grade certification (International Protection Marking), which means that the protection ability of the shell of electrical equipment against foreign bodies (dust, liquid, etc.) is a basic and important indicator of electronic equipment.
The IP level usually starts with “IP” and is followed by two digits, such as the IP69 passed by Redmi Note 13 Pro+.
The first number is solid protection, which is what we often call the “dust” coefficient.
The second number is liquid protection, which is often referred to as the “waterproof” factor.
After inquiry, it is known that the standard test of IPX9 waterproof grade requires the number of spray holes to be 4; There are 4 nozzle angles, respectively 0°, 30°, 60°, 90°; The water temperature is divided into normal temperature 25℃ and 80±5℃. The water spray pressure is 8000~10000Kpa; The spray impact force is 0.9~1.2N; The total time is 120S, and each angular position is tested for 30S.
Simply put, IP69-enabled equipment can withstand high pressure and high temperature water/steam flushing.
In addition, IP69 does not mean that it has a stronger anti-flooding effect than IP68, which have different test standards.
