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.
• A salt spray ‘pollution’ phase. This may be similar to the traditional salt spray test although in some cases direct impingement by the salt solution on the test specimens, or even complete immersion in salt water, is required. However, this ‘pollution’ phase is generally shorter in duration than a traditional salt spray test.
In salt spray tests zinc flake coatings demonstrate better protection against corrosion than a typical galvanic zinc coating, which in the tests (generally run in accordance with ISO 9227) often achieve only 96 to 200 hours.

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 ...
