IPX5 Water Spray Test Chamber for Automotive Lighting
The IPX5 water spray test chamber for automotive lighting is specifically designed to test the waterproof performance of vehicle lights (e.g., headlights, taillights, turn signals) under water jet (IPX5-rated) conditions.
With this chamber, you can confidently evaluate your products against stringent IPX56 standards, guaranteeing their reliability and performance under challenging conditions. By integrating advanced functionality, this chamber meets the diverse needs of various industries, ranging from automotive to electronics.
- IPX5 Water Spray Test Standards
Applicable Standards:
IEC 60529 (International Electrotechnical Commission)
GB/T 4208 (Chinese National Standard)
ISO 20653 (Automotive Protection Standard)
OEM Standards (e.g., VW 80000, GMW 3172 may have additional requirements)
IPX5 Test Conditions:
Nozzle Diameter: 6.3 mm
Water Flow Rate: 12.5 ± 0.625 L/min
Water Pressure: 30–100 kPa (adjustable)
Spray Duration: Minimum 3 minutes (some OEMs require longer)
Spray Distance: 2.5–3 m (to ensure water jet impact)
Water Temperature: Room temperature or adjustable (e.g., 5°C–40°C for environmental simulation)
- Components of an IPX5 Water Spray Test Chamber for Automotive Lighting
Component Description
Spray System High-pressure pump + IPX5 standard nozzle for compliant water flow
Turntable 360° rotation to simulate multi-angle spraying (some models support speed adjustment)
Water Tank & Filtration Recirculating water system, optional deionized water (prevents scaling)
Control System PLC or touchscreen for setting spray time, angle, pressure, etc.
Chamber Structure Stainless steel + tempered glass observation window (anti-corrosion)
Drainage System Quick drainage to prevent water accumulation - IPX5 Test Procedure for Automotive Lighting
Sample Mounting: Secure the light fixture on the turntable, ensuring sealing surfaces face the spray.
Parameter Setting: Adjust water pressure (e.g., 100 kPa), flow rate (12.5 L/min), and duration (3–10 min).
Test Execution: Start spraying while the turntable rotates (e.g., 10 rpm) for full coverage.
Result Evaluation:
Pass: No water ingress, normal functionality (e.g., post-spray power-on test).
Fail: Water leakage, fogging, or electrical failure.
- Key Selection Criteria (for Automotive Lighting)
Spray Coverage: Must accommodate the largest light dimensions (e.g., 500 mm length).
Water Temperature Control (Optional): Simulate low (5°C) or high (40°C) temperature sprays.
Automation (Optional):
Automatic logging (e.g., humidity sensors for moisture detection).
Integration with electrical tests (e.g., automatic power-on after spraying).
OEM Compliance: Some automakers (e.g., Volkswagen, Toyota) may require stricter test conditions.
- Precautions
Nozzle Calibration: Regularly verify water flow compliance (using a flow meter).
Water Quality: Deionized water is recommended to prevent nozzle clogging.
Safety: Keep the chamber door closed during high-pressure spraying to avoid electrical hazards.
Conclusion
The core function of an IPX5 water spray test chamber for automotive lighting is to simulate heavy rain or car wash conditions, ensuring waterproof integrity. Key selection factors include nozzle accuracy, turntable stability, and OEM compliance. For specific model recommendations or test optimization, provide additional details (e.g., budget, testing volume).
