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.
Salt concentration by weight is about 3.5% in sea water. With spray from waves and by other means, salt gets into the air as an aerosol, and eventually as a dust-like particle. This salt dust can be found everywhere near the coast. Salt is hygroscopic, and this property makes it harmful to coatings.

Environmental testing is the measurement of the performance of equipment under specified environmental conditions. [1] This can include the following: [2] [3] High and low extreme temperatures; Temperature cycling; Sand and dust exposure; Salt spray; High and low humidity; Wet environments; Deep water submersion; Corrosive material exposure ...
• 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.
MIL-STD-810 is maintained by a Tri-Service partnership that includes the United States Air Force, Army, and Navy. [2] The U.S. Army Test and Evaluation Command, or ATEC, serves as Lead Standardization Activity / Preparing Activity, and is chartered under the Defense Standardization Program (DSP) with maintaining the functional expertise and serving as the DoD-wide technical focal point for the ...
Spraying. The coating material is applied to the parts' surface using a spray gun. This can be done manually or in a fully automated spraying facility (this process is used for larger or unwieldy parts, also termed rack parts, as they are brought into the coating process on a rack). Dip-spinning. The parts get loaded into a basket.
The Kesternich test is a common name for the corrosion test with sulfur dioxide (SO 2) under general moisture condensation. This test was developed in 1951 by Wilhelm Kesternich [1] to simulate the damaging effects of acid rain. Acid rain and acidic industrial pollutants are corrosive and can degrade coatings and plated surfaces. Kesternich ...
