With the development of the times, the structure and function of the product are getting better and better, and the constant updating of consumer electronics requires more and more high IP dust and waterproof grades, such as IP65, IP66, IP67, IP68, and even some high-precision products can reach IP69K.



So the level of IP dust and water resistance is determined by the purpose 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. IP dustproof and waterproof testing is used to test the ability of products to prevent the penetration of water, dust, and foreign objects.



So why do products need to undergo IP dustproof and waterproof testing?

There are several reasons for conducting IP dust and waterproof testing, including safety, functionality, and product marketing.



Many products require insulation from external components in order to function properly. These external factors include fog, steam, water spray, sand, oil, and even fingers, to name just a few. IP dustproof and waterproof testing helps to determine whether a specific product can function properly when used on site (such as underwater lights that need to pass the IP68 rating).



IP Dust and Waterproof Testing Standard Classification?

The commonly used standards for IP dust and waterproof testing include GB/T 4208 (national standard), IEC 60529 (International Electrotechnical Commission), MIL-STD-810 (military), and RTCA/DO-160 (Aviation Radio Technical Committee).



How to define the IP dustproof and waterproof test level?

IP rating is used to define the sealing effectiveness level of electrical enclosures to prevent foreign objects (including dust and moisture) from entering. Each number after the IP has a specific meaning. The first represents the level of protection of enclosed equipment against foreign objects, commonly known as dust level. The second definition defines the level of protection of the casing from various forms of moisture, namely the waterproof level.



IP dust level judgment:



IP1X: Effective for foreign objects greater than 50mm.



IP2X: Effective for foreign objects larger than 12.5mm.



IP3X: Effective for foreign objects larger than 2.5mm.



IP4X: Effective for foreign objects greater than 1mm.



IP5X: Dust proof, some dust may pass through, but not enough to damage the product.



IP6X: Completely dustproof.



IP waterproof level judgment:



IPX1: Prevent water droplets from falling vertically for 10 minutes, equivalent to 1mm of rainfall per minute.



IPX2: When tilted 15 ° from the normal position, it can prevent the equipment from soaking in water for 10 minutes. Equivalent to 3mm of 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 onto the casing from any direction for 10 minutes. Water volume: 10 liters per minute. The pressure is 50-150kPa.



IPX5: nozzle(6.3mm) Spray water from any direction towards the casing for 3 minutes. Water volume: 12.5 liters per minute, pressure: 30 kPa.



IPX6: Water is sprayed onto the casing with a powerful jet (12.5mm) from any direction for 3 minutes. Water volume: 100 liters per minute Pressure: 100 kPa.



IPX7: Immerse in 1 meter deep water for 30 minutes.



IPX8: Soak in 1 meter deep water for more than 1 hour. The manufacturer will specify the exact usage conditions based on the model.
