Professional Construction & Technical Precision
The Rain Spray Test Chamber is constructed with premium SUS304 stainless steel throughout the interior and exterior, providing excellent corrosion resistance and long-term durability in humid testing environments. It incorporates a precision-engineered rain test spray head with dedicated nozzles for both R1/R2 sprinkling and S1/S2 high-pressure spray modes.
Dual-motor drive system (Panasonic servo motor for the turntable and stepper motor for the water pipe shaft) ensures smooth, stable, and highly repeatable rotation. Advanced closed-loop control using high-accuracy flow meters and pressure sensors, combined with PLC intelligent regulation, maintains precise test conditions throughout the entire test cycle. The large tempered glass observation window and independent exhaust/ventilation system allow operators to safely monitor the test process while maintaining optimal environmental conditions inside the chamber.
Testing Principle
The test specimen is securely mounted on the rotating turntable inside the chamber. The system then simulates four distinct JIS D0203 conditions โ R1 and R2 (natural rain sprinkling) and S1 and S2 (high-pressure water spray) โ by precisely controlling water flow rate, pressure, spray angle, and rotation speed. After the specified test duration, the specimen is carefully inspected for water ingress, functional performance degradation, and sealing integrity to determine whether it meets the waterproof requirements defined in JIS D0203.
Common Error Mitigation
To achieve accurate, repeatable, and reliable test results, the following best practices are strongly recommended:
- Calibrate water flow rate and pressure before each test series using certified instruments
- Ensure correct specimen positioning, secure mounting, and proper orientation on the turntable
- Use clean, deionized or filtered water to prevent nozzle clogging and maintain spray uniformity
- Maintain stable laboratory ambient conditions and regularly inspect the spray head for wear
- Record all key test parameters (flow rate, pressure, duration, rotation speed, and observations) for full traceability and data analysis
Primary Use Cases & Business Value
This Rain Spray Test Chamber is critical for automotive manufacturers and suppliers to validate waterproof design, identify potential sealing weaknesses early in the development process, and ensure compliance with JIS D0203 and customer-specific requirements. By simulating real-world rain and high-pressure spray conditions, it helps significantly reduce field failures caused by water ingress, shortens product development cycles, and strengthens overall product reliability and market competitiveness.
