JIS D0203 rain test chamber is manufactured according to JIS D0203 standard. It is mainly used to test the waterproof performance of auto parts in simulated natural rain environment. The JIS D0203 rain test chamber can perform R1 R2 rain test: 2 rain nozzles, hole diameterΦ1.2mm and s1 s2 spray test: 40 spray nozzles, hole diameterΦ0.5mm.
Model: R-1000JIS
Standard: JIS D 0203
1. JIS D0203 rain test chamber fully covers a variety of different rain test methods specified in JIS D0203 standard, such as R1, R2, S1, S2.
2. Precise control of key parameters such as angle, pressure and flow rate of water injection. Simulate rainfall of different intensity and angle to accurately evaluate the waterproof performance of auto parts under various rainfall conditions.
R1 Test | R2 Test | S1 Test | S2 Test | |
Water spray pressure | 0.3kgf/cm² (about 4.3psi) | 0.1kgf/cm² (about 1.4psi) | 1kgf/cm² (about 14.2 psi) | 3kgf/cm² (about 42.7 psi) |
Flow rate | 0.8 gal/min (about 3.2 L/min) | 0.5 gal/min (about 1.9 L/min) | 6.5 gallons/min (about 24.5L /min) | 10.3 gal/min (about 39.2 L/min) |
Test duration | 10 minutes | 10 minutes | 30 minutes | 60 minutes |
Nozzle | 2 | 2 | 40 | 40 |
3. The automatic inlet filtration system can filter impurities in 0.03mm particles to ensure the smooth spraying system. At the same time, test the water circulation system in the rain test chamber to reduce water consumption.
4. SUS304 stainless steel is used, which has good corrosion resistance and strength, and can withstand the impact and corrosion of spray water for a long time.
