Waterproof testing is crucial for ensuring the reliability and safety of products in various usage environments. LIB's IPX1/IPX2 Rain Test Chamber employs both vertical drip and 15° inclined drip methods to rigorously evaluate a product's ability to resist water ingress under varied exposure angles.
LIB offers a complete range of waterproof testing solutions from IPX1 to IPX9K, covering drip, spray, jet, immersion, and high-pressure wash tests. These systems are designed to meet diverse application needs across automotive, military, outdoor electronics, and industrial equipment, with full compliance to international standards and flexible customization options.
LIB Rain Spray Test Chamber: IPX1 vs. IPX2 Test Method Comparison

IPX1/IPX2 Rain Test Chamber
IPX2 adds an inclination angle to the IPX1 conditions, better simulating the risk of water seeping into the side of the shell during actual use. IPX2 spray test chamber is more efficient movement to the name. LIB can get more useful worth of spray and intelligent PID controller.
|
Test Item |
IPX1 (Vertical Drip) |
IPX2 (Inclined Drip) |
|
Water Source |
Water drips from fixed holes on the top plate of the test chamber. |
Under the same vertical dripping condition as IPX1, the sample is mounted on a 15° inclined tray. |
|
Drip Rate |
1 ml/min (hole diameter φ0.4 mm, spacing 20 mm) |
3 ml/min (same specifications) |
|
Hole Arrangement |
Evenly distributed under the top plate. |
Same as IPX1 |
|
Sample Holder Structure |
Fixed horizontally, no rotating table required. |
Equipped with a 15° inclined tray for quick installation/removal. |
|
Test Duration |
10 minutes |
2 minutes (or as per standard requirement) |
|
Evaluation Criteria |
No water ingress or functional impact on the sample. |
Drip direction changes, checking if sealing is effective on the inclined surface. |
The Core Advantages of The LIB IPX1 IPX2 Rain Test Chamber
Top Drip Box Design
- The top drip box is pre-installed with stainless steel drip holes (φ0.4 mm, spacing 20 mm), which can be easily replaced or added according to different specifications.

Precise Drip Control
- Two options available: built-in flowmeter + pressure gauge, with flexible flow adjustment range, ensuring high-precision output of 1 ml/min and 3 ml/min.
- Automatic water circulation and filtration system eliminates the need for manual water changes throughout the year, effectively preventing nozzle blockages and saving energy.

Water filtration system
Corrosion-resistant materials and structure
- Internal components made of 304 stainless steel for corrosion resistance and easy cleaning; external components made of A3 steel plates for aesthetic appeal and longevity.
- Viewing window equipped with a manual wiper for real-time inspection of the specimen surface; built-in lighting ensures good visibility during testing.

Viewing window and wiper
Humanized and adjustable operation
- Turntable height adjustable from 350–500 mm to accommodate specimens of different sizes; rotation speed of 1 r/min simulates continuous rotation conditions.
- The turntable with an internal power supply allows users to power samples to simulate a more realistic environment.
- The 15° inclined turntable can be installed/removed with a single button, and switching between IPX1 and IPX2 is simple and error-free.
-

Turntable
- The PID controller supports multi-language interfaces, with test programs starting with a single click. Test data can be exported via USB for convenient report generation and traceability. Remote control via computer connection and simultaneous control of multiple devices.
