Salt testing can have different variations such as salt atmosphere, corrosion, salt fog, salt spray testing, etc. Common among these variations is the goal of determining the effects of salt on a product. Salt can have detrimental effects on the physical, electrical, and optical device under test.

The worst effects of salt occur near coasts. Other areas are do not have high salt content but are nonetheless still exposed. Because of such differing salt content, there are different objectives for different salt spray testing. Some standards may call for a corrosion or pitting visual inspection. While other standards test the ability of the product to prevent clogging or buildup.

Salt spray testing laboratories will have a chamber that will not affect the corrosive of the salt atmosphere. The chambers will have appropriate nozzles and venting. Common salt solutions consist of distilled water and sodium chloride will be used. Experior Labs has the visual inspection testing and measurement tools to check for physical damage or corrosion.

It is nearly impossible to avoid exposure to salt. It is found in the atmosphere, ground, lakes, and rivers. The highest content of salt is near the ocean and sea. Product manufacturers intending to use their component or devices in any of these areas should have a salt spray testing requirement. Indeed, many military testing qualification or requirements specification have salt testing.
