SalznebelTest
Salznebeltest, known in English as the salt spray test, is a standardized corrosion test used to evaluate the resistance of metals and coatings to saline environments. The test subjects coated or bare metal specimens to a fine saline mist to simulate exposure to sea air, road salt, and similar corrosive conditions. It is widely used in industries such as automotive, aerospace, marine, and infrastructure to compare protective coatings and materials.
In typical practice, a salt solution of about 5% sodium chloride in water is atomized inside a
Standards such as ISO 9227 and ASTM B117 govern test conditions, specimen preparation, and evaluation criteria.
Historically developed in the mid-20th century, the test remains a common and practical method for assessing
