Parts Included in the Salt Spray Test

  • Three (3) UltraOx®'d cylinders; with nominal dimensions: 0.75”dia. x 1.18” length
  • Three (3) UltraOx®'d cylinders; with nominal dimensions: 0.79”dia. x 1.83” length

The Salt Spray Method

The samples were placed horizontal in the chamber, as seen below, and exposed for the duration of 300 hours, under the following ASTM B117-16 “Standard Practice for Operating Salt Spray (Fog) Apparatus” conditions:

  • Test Media: 5% Salt Solution
  • Cabinet Temperature: 95 to 96ºF
  • Fog Collection Rate: 1.1 to 1.8 ml/hr
  • Specific Gravity: 1.034 to 1.035
  • pH Range: 6.6 to 6.8
  • Tower Temperature: 112 -113 °F
  • Pressure: 12 psi
