Rain/Spray testing per JIS Speed and rate controlled rotating rain and spray nozzles

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
