Application:
Salt spray testing provides the best possible laboratory simulation of natural atmospheric corrosion. Research indicates that test results are similar to outdoors in resulting structure, morphology, and relative corrosion rates.
Salt spray (a continuous salt spray at 35˚C), was the standard way to simulate corrosion in a lab. Because conventional salt spray methods failed to mimic the natural wet/dry cycles of the outdoors, test results frequently provided poor correlation to outdoors.
Continuous salt spray exposures are widely specified for testing components and coatings for corrosion resistance. Applications include plated and painted finishes, aerospace and military components, and electrical/electronic systems.
Most of these tests are performed to particular specifications such as ASTM B117 (Salt Spray), and BS 3900 F4. These tests are widely used for relative corrosion testing. They are typically run at an elevated temperature and do not incorporate a dry-off cycle. They require heated, humidified air for the spray.
