IP standard (IP rating)

The IP standard indicates how resistant an electric device is to foreign matter such as water and dust. "IP" stands for "Ingress Protection" and the protection ratings have been defined by the IEC (International Electrotechnical Commission) and JIS (Japanese Industrial Standards). A protection rating is represented with the letters "IP" followed by two numbers. The first number indicates the dust resistance rating, and the second number indicates the water resistance rating. The higher the number, the higher the dust or water protection level is. There are many IP-rated products around us, including smartphones, outdoor waterproof speakers, and devices used in humid environments such as swimming pools and in outdoor environments exposed to rain.
