With the development of the times, the better the structure and dust and water-proof function of products, and the higher the requirement of IP dust and water-proof level for consumer electronic products, such as IP65 level, IP66 level, IP67 level, IP68 level, and even some high-precision products can reach IP69K level.

Therefore, the level of IP dust and water proof is determined by the use of the product and the 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 seam between the two parts. IP Dust and Waterproof Testing is used to test the product's ability to prevent water, dust and foreign objects from penetrating.

So why does the product need IP dust and water proof test?

There are several reasons for IP dust and water proof testing, including security, functionality, and product marketing.

Many products need to be insulated from external components to function properly. These external factors include fog, steam, spray, sand, oil and even fingers, to name a few. IP dust and water proof testing helps determine whether a particular product will function properly in the field (e.g. a submarine lamp used underwater requires an IP68 rating).

IP Dust and Waterproof Test Standard Classification?

Common IP standards for dust and water proof testing are GB/T 4208 (national standard), IEC 60529 (International Electrotechnical Commission), MIL-STD-810 (military), and RTCA/DO-160 (Aviation Radio Technology Committee).

How do I define the IP dust and water proof test level?

The IP level is the level of sealing used to define the electrical housing against foreign objects, including dust and moisture. Each number following IP has a specific meaning. The first indicates the level of protection of the enclosing equipment against foreign objects, which is commonly referred to as the dust level. The second defines the level of protection of the housing from various forms of moisture, i.e. the level of water resistance.

IP dust level judgment:

IP1X: Effective for foreign bodies larger than 50 mm.

IP2X: Effective for foreign bodies larger than 12.5mm.

IP3X: Effective for foreign bodies larger than 2.5mm.

IP4X: Effective for foreign bodies larger than 1mm.

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

IP6X: Fully dust-proof.

IP Waterproof Level Judgment:

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

IPX2: When tilting 15 degrees from normal position, it can prevent the device from being immersed for 10 minutes. Equivalent to 3 mm of rain per minute.

IPX3: Water drops in a spray at an angle of 60 degrees from the vertical direction for 10 minutes. Water volume: 10 liters per minute. Pressure: 50-150 kPa.

IPX4: Water splashes on the housing in any direction for 10 minutes. Water volume: 10 liters per minute. Pressure 50-150 kPa.

IPX5: The nozzle (6.3mm) sprays water from any direction to the housing for 3 minutes. Water volume: 12.5 liters per minute, pressure: 30 kPa.

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

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

IPX8: Soak in water 1 meter deep for more than 1 hour. The manufacturer will specify the exact conditions of use according to the model.
