When products are exposed to outdoor environments, water rarely arrives softly. From heavy rainfall to directional hose spraying, even a brief failure of sealing can lead to corrosion, electrical short-circuiting, or expensive field returns.
To verify real-world waterproof reliability, engineers rely on standardized jet-spray tests-IPX5 and IPX6-defined under IEC 60529, ISO 20653, and DIN 40050-9.
LIB's IPX5/IPX6 Waterproofing Test Machine provides a precise, safe, and standards-compliant solution that reproduces both moderate-pressure and high-pressure water-jet exposure. Built with high-accuracy flow control, durable stainless-steel construction, and smart safety systems, it ensures reproducible results trusted by laboratories and manufacturers worldwide.
Products Requiring Waterproofing Tests & Relevant International Standards
Waterproofing reliability is essential for products exposed to rain, hose-jet cleaning, road splash, or outdoor installation. IPX5/IPX6 testing is widely applied across multiple industries to ensure that enclosures, electronics, and mechanical components can withstand sustained directional water jets without leakage or failure.
Automotive Components
Automotive systems mounted outside the cabin experience intense water exposure from pressure-washing, high-speed driving, and underbody spray. Typical test objects include:
- Headlamps and tail lamps
- Parking sensors and radar modules
- Surround-view and rear-view cameras
- Charging ports, door-handle electronics, and exterior control modules
Applicable Standard:
ISO 20653 (Road Vehicles – Degrees of Protection)
IPX5/IPX6: Automotive jet-spray protection
IPX9K: High-pressure (8000–10000 kPa), high-temperature (+80–+90 °C) spray for vehicle cleaning environments
Lighting Fixtures
Outdoor luminaires must survive heavy rain, roadside splash, and long-term weather exposure. Typical test items include:
- LED streetlights and roadway lights
- Tunnel lighting systems
- Outdoor architectural lighting
- Waterproof LED enclosures
Applicable Standard:
IEC 60529 (IP Code Standard)
| Item | IPX5 | IPX6 |
|---|---|---|
| Nozzle Diameter | 6.3 mm | 12.5 mm |
| Flow Rate | 12.5 L/min ± 5% | 100 L/min ± 5% |
| Water Pressure | 30–100 kPa | 100 ± 5 kPa |
| Test Distance | 2.5–3 m | 2.5–3 m |
Home Appliances
Outdoor or water-contact appliances rely on sealed housings to prevent corrosion, electrical faults, or insulation failure. Products commonly tested include:
- Outdoor air-conditioning units
- Cleaning machines and pressure washers
- Electric toothbrushes
- Electric kettles and kitchen appliances with water exposure
Applicable Standard:
IEC 60529 (IPX5/IPX6 for household and commercial equipment)
Electronic & Smart Devices
Modern smart devices are frequently marketed as "waterproof" or "weather-resistant," requiring formal IP certification. Typical products include:
- Smart speakers and outdoor security cameras
- Wearable devices such as watches or fitness trackers
- Smart locks and access-control systems
- Portable consumer electronics used outdoors
Applicable Standard:
IEC 60529 – defining global waterproofing performance requirements
Why These Standards Matter
IEC 60529, ISO 20653, and DIN 40050-9 specify strict numerical requirements-nozzle diameters, flow rates, pressures, and distances-to ensure repeatable, globally accepted waterproof testing. By following these values (such as 12.5 L/min, 100 L/min, and 100 ± 5 kPa), laboratories can certify products with confidence that they will withstand real-world water-jet conditions.

Advantages of LIB IPX5/IPX6 Waterproofing Test Machine
LIB's IPX5/IPX6 chamber is engineered to deliver repeatable results while meeting every numerical requirement of IEC 60529, ISO 20653, and DIN 40050-9.
Can the machine perform IPX5 and IPX6 at the same time?
No - not simultaneously.
The chamber includes two precision stainless-steel nozzles (6.3 mm and 12.5 mm) that can be changed quickly. Each mode is controlled independently to maintain the correct flow rate and water-jet intensity.

Testing Procedure for Lighting Fixtures Using LIB IPX5/IPX6 Waterproofing Test Machine
Outdoor lighting products-such as streetlights, garden lamps, and stadium luminaires-must endure strong rainfall, splashes, and pressure-jet cleaning. Testing them under IPX5/IPX6 conditions ensures their structural sealing, gasket compression, and wiring pathways are reliable long-term.

Step 1: Prepare the Fixture
Inspect enclosure screws, seals, and cable glands.
If needed, energize the lamp via the built-in 16 A / 250 V AC waterproof power port.
Fix the lighting fixture on the turntable using clamps or cable ties (recommended for small devices).
Step 2: Select the Test Level (IPX5 or IPX6)
Install the appropriate nozzle:
6.3 mm for IPX5
12.5 mm for IPX6
Set spray distance to 2.5–3 m.
Verify flow rate:
12.5 L/min for IPX5
100 L/min for IPX6
Step 3: Start Continuous Water Jet Testing
The system's PID controller keeps flow and pressure within ±5% accuracy.
Turntable rotates at 1 r/min to ensure full coverage of all sides.
Typical spraying duration: 2–3 minutes per surface, or continuous rotation for 10–15 minutes depending on certification protocol.
Step 4: Observe Through the View Window
The tempered-glass window withstands impact from IPX6 jets without damage.
LED lighting ensures visibility even when droplets hit the window.
Step 5: Post-Test Inspection
Open the housing and check for moisture, condensation, or water penetration.
Document results and store data via USB or Ethernet export.
FAQs on IPX5/IPX6 Waterproofing Test Machine
Q1: Since water pressure is high in IPX5/IPX6 testing, are fixtures provided to secure specimens?
A1: Yes. To keep small specimens stable under high pressure (IPX5 ≈ 30 kPa; IPX6 ≈ 100 kPa), the turntable is equipped with cable ties or clamps. These tools securely fix the samples and ensure safe, reliable testing.
Q2: What is the rated current and voltage of the waterproof power supply? If customers need higher power, can it be customized?
A2: According to IEC 60529 requirements, the built-in power supply supports 16 A and 250 V AC. If the customer needs higher power, LIB can provide non-standard customization with suitable terminals to ensure safe operation.
Q3: Because the spray pipe is at the rear, will water hit the door or window? Will this affect visibility or damage the chamber?
A3: During IPX5/IPX6 spraying, some water may reach the door and viewing window. The window is made of tempered glass, so it will not be damaged. Light water mist does not obstruct visibility; operators can still clearly monitor the test.
Q4: How is water flow controlled in the Rain Test Chamber?
A4: Water flow is precisely controlled using a built-in pressure gauge and flowmeter. Operators can monitor and adjust flow in real time to ensure compliance with standard requirements and maintain testing accuracy.
Q5: Can the turntable of the Rain Test Chamber be made larger?
A5: Yes. The turntable can be enlarged based on customer needs, with sizing adjusted according to the chamber's overall structure. LIB fully supports such customization to ensure functionality and safety.
Any customization can be made. LIB offers a 3-year warranty and lifetime service. Any issues that cannot be resolved during the warranty period will be replaced free of charge. 24/7 English-speaking after-sales team. Fast shipping within 7-15 days.
