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.
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 ...
Various manufacturers, such as car companies and their suppliers, have produced their own specifications and supply rules in order to define the requirements for these coating systems. Zinc flake coating is a generic term for the coating technology and this is marketed by the different suppliers under their respective brand names.
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 ...
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 is nothing new, however, social media users are panicking over the strange interview tactic after an old Reddit post from an Air Force chief was recently resurfaced in various publications.
