Salt Spray Testing for Powder-Coated Parts

What salt-spray testing can and cannot tell you about a powder-coating system.

What the test is for

Salt-spray testing exposes coated specimens to a controlled corrosive environment for a specified duration. It is useful when a customer specification calls for an accelerated corrosion benchmark and defines how the specimen is prepared and evaluated.

Why hours alone are not enough

A requirement such as '1,000 hours salt spray' is incomplete without the test method, substrate, pretreatment, scribe condition, evaluation method and allowable corrosion or blistering.

What to put on the RFQ

  • Applicable test method and revision
  • Exposure duration
  • Specimen preparation
  • Scribe condition if applicable
  • Maximum allowable creep, blistering or corrosion
  • Reporting and sampling requirements
