A salt spray test is acorrosion testingmethod that uses high-saline environments to measure the corrosion resistance of products, paints and coatings over extended periods.
Sometimes referred to as salt fog, a salt spray test is conducted in a closed chamber that can be adjusted to create a variety of corrosive environments. During testing, samples are subjected to a specified salt concentration for a pre-determined amount of time, based on specification, product type, or industry standards.
Salt spray test conditions
In a typical salt spray test, a standardized solution of 5% NaCl (sodium chloride) is used to create a highly corrosive atmosphere. For projects with additional requirements, we can often adjust environmental conditions like temperature and humidity to simulate specific climates or working conditions.
Samples are often checked at regular intervals to monitor corrosion levels and record any milestones, such as white and red rust development or coating degradation. Our labs can provide detailed test reports that include pictures and descriptions of each stage of testing, from start to finish.
