Box Rain Test Chamber

Box rain test chamber/ IP Rain spray test chambers

Configured for your specific tests

Grande 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 specification requirements, and can also accomplish individual automaker’s tests, as well as electrical-enclosure tests.

Heavy splash/shower

· S1 Spray room temperature water with 40 nozzles at 14.2 psi (1 kgf/cm2) for 30 minutes. The flow rate of the water shall be 6.5 gallons/min. (24.5 L/m).

· S2 Spray room temperature water with 40 nozzles at 42.7 psi (3 kgf/cm2) for 60 minutes. The flow rate of the water shall be 10.3 gallons/min. (39.2 L/m).

Light spray/rain

· R1 Spray room temperature water with two nozzles at 4.3 psi (0.3 kgf/cm2) for 10 minutes. The flow rate of the water shall be 0.8 gallons/min. (3.2 L/m).

· R2 Spray room temperature water with two nozzles at 1.4 psi (0.1 kgf/cm2) for 10 minutes. The flow rate of the water shall be 0.5 gallons/min. (1.9 L/m).

Examples of OEM automotive manufacturers' requirements

· Heat the sample to a temperature above boiling, then spray with cold water for about two minutes. Repeat cycle.

· Heat the sample to boiling temperature, then spray with room temperature water for about fifteen minutes. Repeat cycle.

· Simulate a car wash by using high pressure spray.

Features

· Rotating rain and spray nozzles designed to JIS specifications

· Speed control for the rotating spray nozzles

· Stationary product shelf - A rotating shelf is optional: see options

· Water pressure regulators, gauges and flow meters

· Special high-volume floor drain system to rapidly drain water out of the chamber

· Interior chamber size is the smallest possible area using the JIS specified nozzles

Applicable Test Methods

· JSA JIS (Japanese Industrial Standard) D 0203 "Method of Moisture, Rain and Spray Test for Automobile Parts"

· SAE (Society of Automotive Engineers) J2245 "Recommended Practice for Splash and Spray Evaluation"

· SAE J575 "Test Methods and Equipment for Lighting Devices and Components"

"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.
