Salt corrosion spray test chamber

Salt corrosion spray test chamber

Configured for your specific tests

Alternate Salt Corrosion Spray Test ChamberGrande 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 thespecification requirements, and can also accomplish individual automaker’s tests, as well as electrical-enclosure tests.

Our Design

Grande'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.

Testing capabilities

Thespecificationis modeled after 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.

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.

Optional/additional test capabilities:

Temperature/humidity controlled rain chamber: Includes -20 to 150°C and 20 to 98%RH capabilities

Water recirculation: Allows re-use of the treated rain water

Water conditioning: Allows the water to be cooled (5 to 20°C) prior to spray

High pressure spray: Adds capability to meet car wash test requirement

Drip nozzle: Adds capability to meet drip test requirement

Rotating table: Rotates the sample for full exposure to spray
