What’s JIS D 0203 Rain Test Chamber ? JIS D 0203 Rain test chamber is manufactured in accordance with the test requirements of R1, R2, S1 and S2 in JIS D0203 test methods for humidity and water resistance of automobile parts. The JIS D 0203 Rain test chamber suitable for the wet and water resistance test methods of various auto parts.
JIS D 0203 Rain test chamber design allows you to add on additional features, depending on the number and type of tests required. One possible choice is to integrate the spray system with a regular temperature and humidity chamber to save money and floor space, while also creating an opportunity to simulate actual operating conditions your product may experience.
JIS D 0203 Rain test chamber system uses multiple control solenoids to vary the water’s spray volume/pressure. A holding tank prepares the water to the desired temperature, if required. A pump ensures the water is delivered in the proper pressure range. The water is fed to a motorized manifold that rotates the spray arms. Each spray arm has an adjustable valve to allow finer control of the spray.
