ASTM G85

Full Name

ASTM G85 – Standard Practice for Modified Salt Spray (Fog) Testing

Scope

ASTM G85 is a standard practice used to assess the corrosion resistance of metals and coatings exposed to a salt spray environment. This accelerated corrosion test simulates the corrosive effects of marine environments, industrial atmospheres, and other environments where salt is present.

The test involves exposing specimens to a continuous spray of a salt solution at a controlled temperature and humidity. The salt solution is typically a 5% sodium chloride solution. The test duration can vary depending on the specific application and the desired level of corrosion resistance.

After the specified test duration, the specimens are visually inspected for corrosion. The extent of corrosion is evaluated based on factors such as rust formation, pitting, blistering, and cracking. The results of the test can be used to compare the corrosion resistance of different materials or coatings.
