In addition to exterior exposure test sites, the Paint Quality Institute also relies on a variety of panel and paint testing procedures that are unique to industrial paints and painting, and are used to replicate various aspects of the industrial environment. Among these are the following test methods:
  • Corrosion resistance:
    • Salt spray (ASTM B-117)
    • Cyclic salt fog (ASTM D-5894)
    • Electrochemical Impedance Spectroscopy
  • Humidity and water resistance:
    • Humidity cabinet
    • Cleveland condensation cabinet
    • Immersion
    • Fog/rain box
    • Water permeability
  • Flexibility:
    • Impact resistance
    • Mandrel bend
  • Appearance properties:
    • Gloss and sheen
    • DOI – Distinctness-of-image
  • Accelerated weathering:
    • UV weatherometer
    • Xenon arc weatherometer
  • Stability:
    • Shelf stability
    • Heat aging
    • Shear stability
    • Freeze / thaw stability
  • Hardness:
