The salt spray test (or salt fog test) is a standardized and popular corrosion test method, used to check corrosion resistance of materials and surface coatings.Usually, the materials to be tested are metallic (although stone, ceramics, and polymers may also be tested) and finished with a surface coating which is intended to provide a degree of corrosion protection to the underlying metal.
Field immersion comparison chart ASTM B117 Salt Spray Test. The chart on the right shows a comparison of corrosion resistance against other surface treatments, based on field immersion tests. Test conditions for the immersion test are full immersion in 3% sodium chloride plus 3 g /L of hydrogen peroxide for 24 hours. [citation needed]

The test methodology consisted of the ASTM B117 Standard Practice for Operating Salt Spray (Fog) Apparatus [52] which a corrosion expert, retained by the Competition Bureau, adapted in order to replicate the operational environment of an automobile. The test differed from the ASTM B117 insofar as the galvanized automotive steel panels were not ...
Corrosion protection results for various thickness and passivations of zinc mechanical plating, based on ASTM B117 test conditions. The greatest advantage of the process is its ability to overcome hydrogen embrittlement problems, which is important for workpieces that have a hardness greater than HRC 40.
The oil and whiting method used an oil solvent for cleaning followed by the application of a whiting or chalk coating, which absorbed oil from the cracks revealing their locations. Soon a dye was added to the liquid. By the 1940s, the fluorescent or visible dye was added to the oil used to penetrate test objects.
The Bresle method was launched in 1995 in the ISO 8502-6 and ISO 8502-9 standards. The test was developed to measure soluble salt concentration on steel surfaces prior to blasting cleaning and coating. Not only ISO, but also the US Navy, IMO, NAVSEA, and ASTM adopted this method as their standard. The method remains the primary and most ...
