Who Makes the Rain Test Chamber?

Rain, splash, and water ingress are among the top causes of product failure across electronics, automotive, and outdoor gear. A single uncontrolled leak can lead to costly recalls or even safety hazards. That's why rigorous waterproof testing is no longer optional-it's essential for product reliability and compliance.

LIB Environmental Simulation Industry has been designing and manufacturing Rain Test Chambers since 2009, providing full-spectrum testing solutions for automotive, electronics, industrial, and defense sectors. LIB Rain Test Chambers deliver reproducible, standards-compliant results for all levels of water exposure, from light drips to high-pressure jets and deep immersion.

LIB Environmental Simulation Industry produces the Rain Test Chamber, engineered to simulate real-world water exposure conditions. These chambers mimic rainfall, splashing, jets, and submersion to validate the durability and water resistance of products.

A rain test chamber creates controlled water streams and regulates pressure, flow rate, and nozzle angle. Specimens are often placed on a rotating turntable (adjustable height and speed) to ensure uniform coverage. High-precision flowmeters and PID controllers stabilize water jets, ensuring repeatable test results and preventing overstressing the device. This allows manufacturers to predict performance in automotive, electronics, or industrial environments without waiting for real-world rain events.

By simulating environmental conditions such as high-pressure rain, immersion, or spray, the chamber also helps optimize product sealing, design, and material selection. Modern chambers can test multiple samples simultaneously with built-in lighting, observation windows, and optional data export.

Rain tests are classified according to IP (Ingress Protection) ratings defined by IEC 60529, ISO 20653, DIN 40050‑9, JIS D0203, and MIL‑STD‑810G. The second digit of the IP code (0–9K) represents water resistance:

• IPX1 & IPX2: Vertical or 15° inclined drip tests at 1–3 ml/min. Suitable for small electronics, automotive lights, and home appliances.
• IPX3 & IPX4: Oscillating spray tests simulating rain and splashing. Turntable rotation ensures complete surface exposure.
• IPX5 & IPX6: High-pressure jets, 12.5 L/min for IPX5 and 100 L/min for IPX6. Nozzle diameters: 6.3 mm (IPX5), 12.5 mm (IPX6). Pressure: 30–100 kPa (IPX5), 100 ±5 kPa (IPX6). Tests last ≥3 minutes at 2.5–3 m distance.
• IPX7 & IPX8: Static immersion. IPX7: 1 m depth for 30 minutes. IPX8: Custom depth and duration up to 50 m, supporting sensors, batteries, and control modules.
• IPX9K: High-pressure hot water, 80–100 bar at 80 °C, angles 0°, 30°, 60°, 90°. Designed for automotive chassis, military, and industrial equipment under extreme conditions.

These standards ensure products maintain functionality after exposure to water under a wide range of pressures, temperatures, and orientations.

Rain chamber testing reproduces various water exposure scenarios to evaluate product sealing and performance. Water is sprayed, dripped, or jetted at controlled angles and pressures while samples rotate on a turntable to ensure uniform coverage.

LIB Combined Rain Test Chambers (IPX1–IPX6) Advantages:

• Adjustable turntable height (350–500 mm) and rotation (0–7 r/min) for complete surface coverage.
• PID-controlled flow ensures consistent water distribution and repeatable results.
• Stainless steel SUS304 interior resists corrosion; A3 steel exterior maintains structural integrity.
• Built-in filtration and circulation prevent nozzle blockages and maintain long-term stability.
