With the development of the times, the structure and function of the product are getting better and better, and the constant updating of consumer electronic products requires higher and higher IP dust-proof and waterproof grades, such as IP65, IP66, IP67, IP68, and even some high-precision products can reach IP69K.
Therefore, the IP dustproof and waterproof grade is determined according to the use and structure of the product. Different products require different levels of testing and different types of testing. For many products, the most likely point of failure occurs at the joint between two components. The IP dustproof and waterproof test is used to test the product's ability to prevent water, dust and foreign matters from penetrating.
So why should the product be tested for IP dustproof and waterproof?
There are several reasons for IP dustproof and waterproof test, including safety, functionality and product marketing.
Many products require insulation from external components to function properly. These external factors include fog, steam, water spray, sand, oil, and even fingers, to name just a few. The IP dustproof and waterproof test is helpful to determine whether a specific product can operate normally when it is used on the site (for example, the underwater lamp used underwater needs to pass IP68).
IP dustproof and waterproof test standard classification?
The commonly used standards for IP dustproof and waterproof test are GB/T 4208 (national standard), IEC 60529 (International Electrotechnical Commission), MIL-STD-810 (military) and RTCA/DO-160 (Aeronautical Radio Technical Commission).
How to define the IP dustproof and waterproof test grade?
The IP rating is used to define the level of sealing effectiveness of the electrical enclosure against intrusion of foreign materials, including dust and moisture. The numbers after IP each have a specific meaning. The first represents the protection level of the enclosed equipment against foreign matters, which is commonly referred to as the dust-proof level. The second defines the degree of protection of the enclosure against various forms of moisture, namely the degree of water resistance.
Judgment of IP dustproof grade:
IP1X: effective for foreign matters larger than 50mm.
IP2X: effective for foreign matters larger than 12.5mm.
IP3X: effective for foreign matters larger than 2.5mm.
IP4X: effective for foreign matters larger than 1mm.
IP5X: dustproof, some dust may pass through, but it is not enough to damage the product.
IP6X: completely dustproof.
IP waterproof grade judgment:
IPX1: Prevent water droplets from falling vertically for 10 minutes, equivalent to 1mm rainfall per minute.
IPX2: When tilted 15 ° from the normal position, it can prevent the equipment from being immersed in water for 10min. It is equivalent to 3mm rainfall per minute.
IPX3: water falls in the form of spray at an angle of 60 ° to the vertical direction, lasting for 10min. Water volume: 10 liters per minute. Pressure: 50-150kPa.
IPX4: water splashes on the shell from any direction for 10min. Water volume: 10 liters per minute. The pressure is 50-150kPa.
IPX5: the nozzle (6.3mm) sprays water from any direction to the shell for 3min. Water volume: 12.5 liters per minute, pressure: 30 kPa.
IPX6: Water is sprayed onto the shell with a powerful jet (12.5mm) from any direction for 3min. Water volume: 100 liters per minute Pressure: 100 kPa.
IPX7: Immerse in 1m deep water for 30min.
IPX8: Soak in 1 meter deep water for more than 1 hour. The manufacturer will indicate the exact conditions of use according to the model.
