IPX4 is the first grade to provide protection against water entering the equipment from any angle. It is not so high but not so low waterproof rating, for electronic products in daily life, this grade is fully qualified. For many common industrial products, such as electric toothbrushes and Bluetooth headsets, the general waterproof requirements are IPX4, and quality inspector need to use ipx4 waterproof test equipment to check whether their waterproof performance is qualified before they leave the factory.
The IP Code (Ingress Protection Code) is an international standard (IEC 60529) that measures the level of protection provided against the intrusion of solid objects (e.g., dust) and liquids (e.g., water) in electrical enclosures or electronic devices, such as smartphones, tablets, and wearables. The IP code consists of two digits that indicate the level of protection. The first digit denotes the protection against solid objects, and the second digit denotes the protection against liquids. For example, IP68 means the device is dust tight and can be submerged in water up to a certain depth and duration. The IP code is important for ensuring the durability and reliability of electronic devices in different environments.
IP Rating | Degree of Protection Against Solid Foreign Objects | Degree of Protection Against Water |
IP03 | Not Protected | Spraying water |
IP13 | Solid object >50 mm | Spraying water |
IP23 | Solid object >12.5 mm | Spraying water |
IP33 | Solid object>2.5 mm | Spraying water |
IP43 | Solid object>1 mm | Spraying water |
IP53 | Dust protected | Spraying water |
IP63 | Dust tight | Spraying water |
IP04 | Not Protected | Splashing water |
IP14 | Solid object >50 mm | Splashing water |
IP24 | Solid object >12.5 mm | Splashing water |
IP34 | Solid object>2.5 mm | Splashing water |
IP44 | Solid object>1 mm | Splashing water |
IP54 | Dust protected | Splashing water |
IP64 | Dust tight | Splashing water |
IPX4 Splashing Water Testing:
Defined as water splashing against the enclosure from any direction.
The requirement is that the equipment under test (EUT), shall experience no harmful effects from the water being slashed against the enclosure from any direction.
The test details include a test duration of at least five minutes, water volume of 10 liters per minute and pressure of 80-100 Kpa.
The test is performed in a test chamber with the device mounted on a turntable rotating at 1 RPM. The device is inspected after the test to determine whether it has any water ingress or damage. If there is no water ingress or damage, the device can be certified as IPX4 waterproof rated.
IPX4 test equipment introduction
Spraying Hole Diameter: φ0.4 mm
Hole Spacing: 50 mm
Swing Angle of Oscillating Tube：0 ~ ±180° (Adjustable）

Water re-circulation system that reduced water use
LIB specially designed a set of automatic water inlet and water filtration system to filter impurities within 0.03 mm particles, which has ensured the smoothness of the spray system.
1, connect the power supply, the water source, the rain test box is 380V power supply, the water source is directly connected to the water inlet;
2. Fix the sample in the middle of the turntable;
3, turn on the water, the water shortage alarm will be displayed after the boot, click the water switch, the water tank is filled, it will automatically stop;
4, check the needle, will be blocked and deformed needle replacement;
5, need to power test samples, can directly connect the power supply in the inner chamber;
6, confirm the waterproof test level, IPX3 and IPX4 test standards are different, according to the waterproof level to replace the needle or needle holder;
7, adjust the flow meter, according to the flow value on the operation interface to adjust;
8, start the test, the test will be automatically stopped after completion;
To improve your product reliability and durability, which test and the chamber do you need? LIB will provide you with the professional solution.
