ISO 9227 Salt Spray Testing

Assured Testing Services is capable of providing Salt Spray testing in accordance with the ISO 9227 specification requirements.


Salt spray testing provides a controlled accelerated corrosive environment to evaluate the relative corrosion resistance of the coating, substrate, or part itself. Parts or panels are placed inside a chamber and exposed continually for a specified period of time, then evaluated for resistance to corrosion. This type of testing is also known as salt fog testing.


ISO 9227 testing is commonly paired with such auxiliary evaluations listed below.

​Auxiliary Evaluations:

  • ASTM D1654  Scribing and scribe creep evaluation

  • ASTM D610 Degree of rusting

  • ASTM D714 Degree of paint blistering
