JIS D 0203 rain spray chamber is a equipment used to test the waterproof performance according to JIS D 0203 standard, mainly used in auto parts, electronic products, outdoor lamps. The JIS D 0203 rain spray chamber is equipped 40 spray nozzles and 2 rain nozzles to simulate varying degrees of rain.
Model: R-1000JIS
Standard: JIS D 0203
Diversified nozzle configuration: According to JIS D 0203 standard,S1 test uses 40 nozzles, and the S2 test also uses 40 nozzles but with greater spray pressure and flow; R1 and R2 tests use two nozzles.The long tube spray 40 nozzles with a diameter of 1.2mm and a spacing of 12.5mm. The short pipe sprinkler has two 0.5mm thin seams.
R1 test conditions:
- Water spray pressure: 0.3kgf/cm² (about 4.3psi).
- Flow rate: 0.8 gal/min (about 3.2 L/min).
- Test duration: 10 minutes.
- Spray water using 2 nozzles.
R2 Test conditions:
- Water spray pressure: 0.1kgf/cm² (about 1.4psi).
- Flow rate: 0.5 gal/min (about 1.9 L/min).
- Test duration: 10 minutes.
- Spray water using 2 nozzles.
S1 Test conditions:
- Water spray pressure: 1kgf/cm² (about 14.2 psi).
- Flow rate: 6.5 gallons/min (about 24.5 L/min).
- Test duration: 30 minutes.
- Water spraying with 40 nozzles.
S2 Test conditions:
- Water spray pressure: 3kgf/cm² (about 42.7 psi).
- Flow rate: 10.3 gal/min (about 39.2 L/min).
- Test duration: 60 minutes.
- Water spraying with 40 nozzles.
Real rain simulation: the turntable can be rotated and the height can be adjusted to make sure sample get full angle rain spray, and the shaft of the water supply pipe is 45° with the horizontal line,which further enhances the authenticity of the rain test.
Good observation conditions: the JIS D 0203 rain spray chamber adopts transparent observation window equipped with automatic wiper to facilitate observe the internal test situation in real time; LED light is installed at workroom.
Easy operation: The operation interface is simple and convenient for operators to set parameters, remote connection to the PC terminal is also support.

The oscillating tube swings through the motor.The water below filters the impurities in the water into the tank, and the water in the tank is sent to the work room through the pump.Flow meters and pressure probes control water flow and pressure.
During the process of entering the workroom, the water in the tank is equipped with a filter to prevent the nozzle from blocking. The water under the door is introduced into the water tank with a hose.
The water enters the workroom from the water tank, and the water in the working room is introduced into the water tank, forming a water circulation system.
