When products, from automotive parts to outdoor electronics, face water exposure in real-world conditions, manufacturers must ensure they meet strict waterproofing requirements. A rain test chamber provides controlled, repeatable testing to simulate rain, splashes, immersion, and high-pressure water environments.
LIB's Rain Test Chambers combine advanced control systems, modular flexibility, and full compliance with global standards such as IEC 60529, ISO 20653, JIS D0203, DIN 40050‑9, and MIL‑STD‑810G, enabling engineers to verify product water resistance efficiently, reliably, and cost-effectively.
Working Principle of IPX1–6 Rain Test Chamber
LIB's Combined IPX1–6 chambers simulate water ingress at varying intensities and angles. The key principle is to replicate real-world water exposure in a repeatable, measurable way:
|
|
|
 |
|
IPX1 & IPX2 (Drip Tests): Water drips at 1 mm/min. IPX2 tests are performed on a 15° tilted sample, rotated for 2.5 minutes per direction, covering four orientations. Turntables adjust from 350–500 mm height and support up to 50 kg, allowing multi-angle exposure.
IPX3 & IPX4 (Oscillating Tube): Water sprays through φ0.4 mm nozzles with ±60° swing (IPX3) or ±180° swing (IPX4). Spray rate is 0.07 L/min per nozzle, and tests run ≥10 minutes.
IPX5 & IPX6 (High-Pressure Spray): IPX5 uses 6.3 mm nozzles at 12.5 ± 0.625 L/min and 30–100 kPa; IPX6 uses 12.5 mm nozzles at 100 ± 5 L/min and 100 ± 5 kPa. Spray distances range from 2.5–3 m for ≥3 minutes, covering all specimen surfaces.
All water systems use closed-loop circulation with auto-refill, reducing manual intervention, water usage, and energy consumption. Independent piping, valves, and PID-controlled programs enable quick switching between test levels via touchscreen.
LIB's Precision and Energy Efficiency Advantages in IPX1–6, IPX7/8, and IPX9K Rain Test Chambers

| IPX7 IPX8 Water Immersion Test Equipment | IPX9K High Pressure Water Spray Test Chamber |
LIB chambers emphasize precise, reproducible testing and environmental efficiency:
Immersion Testing (IPX7/IPX8): IPX7 simulates 1 m deep water for 30 minutes; IPX8 replicates pressures up to 50 m depth. Pneumatic lids allow safe, fast access.
Extreme Condition Testing (IPX9K): High-pressure jets of 8,000–10,000 kPa at +88 °C rinse samples from four angles, simulating military or industrial environments. Built-in waterproof power ports allow live electronic testing.
Standards Compliance: LIB meets IEC 60529/IPX1–9K, ISO 20653, DIN 40050‑9, JIS D0203, and MIL‑STD‑810G for global regulatory acceptance.
High-Precision Control: PID regulation keeps pressure deviation ≤0.01 kPa, flow rates within 14–16 L/min, and spray distances between 10–15 cm. Multi-angle rinses ensure uniform exposure.
Energy and Water Savings: Closed-loop water systems recycle resources, and automated controls minimize electricity usage during prolonged tests.
