JIS D0203 Rain Test Chamber

Name: JIS D0203 Rain Test Chamber
Brand: Xi'an LIB Environmental Simulation Industry

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

Features and Benefits of JIS D 0203 Rain Test Chamber

1. LIB Industry 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.

①Workroom	The interior of the workroom and the turntable are made of SUS304 stainless steel large viewing glass doors or viewing window with wiper. The equipped waterproof power interface to power up the test specimen. The rotating speed and height of the turntable are adjustable.
②Filter	The automatic inlet filtration system can filter impurities in 0.03mm particles to ensure the uniformity and stability of the spray.
③Water pump	The water pump is the power source of the water circulation system of the rain test chamber, which is responsible for transporting the water in the water tank to the nozzle to form the rain effect.
④Water tank	Supply water for the entire rain test. Water tank equipped with water level float ball valve, can automatically control the water in and out.
⑤Pressure sensor	Measure the water spray pressure.
⑥Motor	Drive turntable and pendulum tube.
