ESPEC makes rain and spray testing easier by offering a standard chamber capable of published and OEM proprietary test methods.
The standardized design can be configured for the rain/spray tests you need, eliminating the guesswork in buying a chamber. The system is based on the JIS/SAE specification requirements, and can also accomplish individual automaker’s tests, as well as electrical-enclosure tests.
ESPEC's modular 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.
Our 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.
The SAE specification J2245 is modeled after the JIS D0203 and doesn’t differ greatly. Details about the nozzle types and the rotating nature of the spray arms and product table are also included in the requirements. Additionally, drip and car wash tests are also specified.
"The cabinet shall be equipped with a nozzle(s) which provides a solid cone water spray of sufficient angle to completely cover the sample device. The centerline of the nozzle(s) shall be directed downward at an angle of 45 degrees to the vertical axis of a rotating test platform... The device shall be rotated about its vertical axis at a rate of 4.0 ± 0.5 rpm... The water spray test shall continue for 12 hours." ref: SAE J575.
