Electronic products currently on the market, such as mobile phones, cameras, and sports watches, often advertise their water resistance. Our common application scenarios include washing hands under the tap, going out on rainy days, and even listening to music while running. Therefore, the waterproof level has become a key technical indicator for product sales.
However, IP ratings are often misunderstood or incorrectly applied. For example, some manufacturers believe that meeting the IP69K standard means meeting both the IP67 and IP68 standards. In fact, IP69K can only provide protection against flushing pressure, and is not suitable for applications that are completely submerged in water. Therefore
, IP69K protection level is usually suitable for applications that require frequent cleaning and flushing, such as brewing systems, medical systems, car washes and food Beverage factory etc. However, it is not suitable for situations where the device is completely submerged in water.
IP68 and IP69K belong to the same IP protection level series, but they represent completely different concepts. After all, IP69K is a later derived level.
Let's first look at the difference between IP69K and IP68:
IP69K protection level:
It withstands the high temperature and high pressure water vapor washout tests defined in the EN 60529 and DIN 40050-9 standards. It is capable of providing a water pressure of up to 100 bar (1450 psi) and a temperature protection of 80°C.
The test standard is to apply pressure directly on the sensor at an angle of 30 degrees (0 degrees, 30 degrees, 60 degrees and 90 degrees), and last for 30 seconds at each angle, a total of 120 seconds (2 minutes). to ensure that water infiltration does not occur
IP (Ingress Protection) is a standard developed by the International Electrotechnical Commission (IEC, International Electrotechnical Commission), which is used to classify the dust and moisture resistance of electrical equipment. This standard determines, based on the characteristics of the equipment, its level of ability to prevent the ingress of dust and moisture
The IP protection class consists of two numbers. The first number indicates the level of dustproof and foreign object intrusion prevention of electrical equipment (this includes tools, human fingers, etc. that cannot touch the live parts inside the electrical appliance to avoid electric shock). The second number indicates the degree of sealing of electrical equipment against moisture and water immersion, and the larger the number, the higher the protection level
