IPX 3/4/4K Waterproof Test Chamber China Manufacturer and Supplier
The IPX3/IPX4/IPX4K Water Spraying & Splashing Test Equipment is a versatile 3-in-1 solution designed to evaluate the ingress protection of enclosures against spraying (IPX3) and splashing water (IPX4/4K). This integrated system allows users to switch between testing ratings seamlessly by adjusting the number of nozzles on the oscillating tube or swapping needles to match required inner diameters. Compared with IPX3 and IPX4, the IPX4K configuration introduces increased water pressure to simulate extreme environmental conditions.
IEC60529 Compliant Oscillating tube and Nozzles
Constructed from high-quality stainless steel, the oscillating tube features a semi-circular design with precision-drilled holes directed toward the center. Each port is equipped with a threaded fitting, allowing for the easy manual installation of spray nozzles and plugs. During operation, water is ejected from the needle in a concentrated stream, providing direct impact on the specimen’s housing to ensure accurate testing results.
To accommodate various sample sizes, the system offers oscillating tubes with multiple radii. The IPX3 oscillating tube sprays water over the sample at an angle up to 60° on either side of the vertical, and the IPX4 oscillating tubes splashes water over the sample from any direction. While IPX4K utilizes the same foundational parameters as IPX4, it operates at higher pressure and flow rates to simulate more severe exposure. All tests require maintaining a standardized 200mm spray distance between the enclosure and the needles. The interior is also outfitted with integrated lighting and a built-in power socket for the Test Under Load (TUL) of the sample.

Open-type IPX3 IPX4 water spray tester
Open-Type vs. Box-Type Solutions
In addition to our integrated box-type rain test chambers, we offer open-type IPX3/4/4K spraying and splashing test equipment for specialized applications. While our standard box-type units typically feature a maximum oscillating tube radius of 800 mm—making them ideal for small to medium-sized products—our open-type systems provide much greater flexibility.
Engineered for Large-Scale Specimens
The open-type configuration allows the oscillating tube radius to extend up to 1600 mm. By removing the constraints of an enclosed chamber, this equipment is the perfect solution for testing large-dimension specimens that cannot fit into standard cabinets. However, please note that unlike self-contained box-type units that can be placed anywhere in a facility, open-type equipment requires a dedicated waterproof room or specialized test site to manage water runoff.
Customizable Configurations
We provide fully customizable specifications to accommodate your specific testing needs. Our swivel tubes are available in eight standard radii: R200, R400, R600, R800, R1000, R1200, R1400, and R1600. As the radius increases, the number of nozzle openings and the total water flow rate are adjusted accordingly to ensure full compliance with international testing standards.
Custom Integrated Test Solutions
If you need to perform multiple levels of IP testing but wish to avoid the cost and footprint of multiple machines, AmadeTech has the answer. We can integrate the hardware for IPX1 through IPX6, and even IPX9K, into a single, multi-functional test chamber. This all-in-one approach significantly streamlines your testing workflow and maximizes laboratory space. Contact our experts today to discuss your custom testing requirements.
Solutions for Complex Specimen Geometries
Certain specimens feature complex shapes or external barriers that prevent an oscillating tube from reaching every surface. In these instances, the IPX3/IPX4 hand-held spray nozzle is the ideal solution. This manual tool bypasses the fixed angles of automated systems, allowing you to direct the spray toward any part of the enclosure for total coverage.

- 1. Connect the appropriate water and power sources to the test device.
- 2. Select and install the oscillating tube fitting the test item.
- 3. Place and fix the sample on the sample turntable of the rain test equipment, so that the central axis of the sample is in the exact center of the turntable.
- 4. Adjust the height of the turntable according to the size of the sample, so that the distance from the top of the sample to the nozzle of the swivel tube does not exceed 200mm.
- 5. Turn on the machine and choose the tube radius on the touch screen, then set the test duration and adjust the water pressure to achieve a stipulated water flow rate.
- 6. Click “Start” button to start the test. The specimen starts to rotate and receives water spray or splash water.
- For IPX3 testing, the tube will swivel through an angle of 120°, 60° on either side of the vertical. The duration for one complete circle (2 x 120°) is about 4 seconds, and the total is 5 min.
- For IPX4 and IPX4K testing, the tube will swivel through an angle of almost 360°, 180° on either side of the vertical. The duration for one complete circle (2 x 360°) is 12 seconds, and the total is 10 min.
- 7. Demount the sample for inspection after the test is terminated. The test is passed If there is no harmful effects or performance impairments on the equipment inside the enclosure.
Products suitable for IPX3/4/4K waterproof testing include but are not limited to electronic components, outdoor lamps, mobile phone casings, auto parts, power batteries, wires and cables, plastic products, chemical products, biomedical products, power engineering products, building materials, military products, etc.
- The box-type test equipment features an enclosed chamber to isolate the test area from the outside. Water will not flow onto the ground or splash onto surrounding objects during the test. Moreover, the test water is collected by the lower tank, then pumped up for recycling. Limited by the structure, the box type can’t be made too large.
- The open-type test device frees from space constraints and allows larger sizes of swivel tubes than that of the box type. It requires a waterproof testing room to carry out the test.
- The IPX3 waterproof test is used to determine the protection ability of the sample enclosure against spraying water. The sample is placed at the center point of the swivel tube semicircle. It requires the tube to swivel through an angle of 120°, 60° on either side of the vertical. The time taken for one round trip (2×120°) of the tube is 4 seconds, and the test duration is 5 minutes. After that, you need to turn the sample through a horizontal angle of 90° and continue the test for a further 5 minutes.
- The IPX4 waterproof test is used to determine the protection ability of the sample enclosure against splashing water. The sample is placed at the center point of the swivel tube semicircle. It requires the tube to swivel through an angle of almost 360°, 180° on either side of the vertical. The time taken for one round trip (2×360°) of the tube is 12 seconds, and the test duration is 10 minutes.
The larger the second digit after the IP code, the higher the waterproof level, so the waterproof level requirement of IPX4 is higher than that of IPX3.
The oscillating tube for IPX3 is provided with spray holes over an arc of 60° on either side of the center point. The oscillating tube for IPX4 has spray holes over the whole 180° of the semicircular tube.
The number of open holes and total water flow varies with the radius of the semicircular tube. For details, please refer to the below table based on IEC 60529:
The oscillating tube in our machine is dismountable. You can freely change between different tubes, which provides flexibility to be compatible with tubes of IPX3 and IPX4. If required, tubes of different radiuses can also be mounted on the same set of stands according to the needs of the test. Especially for open-type test equipment, they have a wider possibility of compatibility with different sizes of tubes over box-type test equipment.
The total water flow rate varies with the number of spray holes. Its formula is as below:
Total water flow rate = Number of spray holes x Mean flow rate per hole
- For IPX3 & IPX4 testing, the mean flow rate per hole is 0.07 l/min. For example. The total flow rate for a IPX3 swivel tube of 200 mm in radius is 8 x 0.07 = 0.56 l/min
- For IPX4K testing, the mean flow rate per hole is (0.6 ± 5%) l/min
Yes, the testing device will be provided with a waterproof socket for the sample requiring being energized while testing if required.
The size of the oscillating tube depends on your sample dimensions. Generally, the relationship between the two is directly proportional.
The specifications of oscillating tubes we supply include but are not limited to R200 mm, R400 mm, R600 mm, R800 mm, R1000 mm, R1200 mm, R1400 mm, and R1600 mm.
If you don’t know which tube size fits your testing, please advise us of your sample dimensions when sending us a quote. Our sales engineers will recommend you the most appropriate model.
Yes. During testing, the turntable can rotate at a set speed. The purpose of rotation is to ensure that all test areas of the sample are covered by water spray from different angles.
For irregularly shaped samples, if there are areas that cannot be covered by water spray with a oscillating tube, it is recommended to use our handheld spray nozzle to complete the test.
The sample size is determined by the diameter of the oscillating tube. Its dimensions must be smaller than the oscillating tube diameter, and the distance between the sample enclosure and the nozzles after installation must not exceed 200mm.
For standard machines, the sample weight must not exceed 50kg; otherwise, overloading will damage the turntable.
Sample installation is simple: just place the sample on the turntable, aligning the turntable’s central axis with the sample’s central axis, and secure the sample with a rope or other auxiliary device to prevent it from falling during testing.
The uniformity of the water spray is excellent.
First, the water supply flow rate of our machine fully meets the standards and is very stable, which is the foundation for the uniform water spray of the oscillating pipe. Second, the needle size and distribution spacing of all nozzles on the oscillating pipe are manufactured according to the IEC 60529 standard. In addition, during testing, the swivel angle and speed of the oscillation of the oscillating pipe fully meet the relevant requirements, ensuring the uniformity and consistency of the water spray.
The main consumable for our IPX3/4 testing equipment is the filter cartridge, which is used to filter impurities from the test water. The filter cartridge needs to be replaced promptly when it turns black.
In addition, the nozzle needle needs to be replaced immediately if it becomes clogged or bent.
