Salt Spray Test for Material Testing

ASTM B117 Salt Spray Test

ASTM B117 is a standard test method for salt spray testing, also known as salt fog testing, which is used to evaluate the corrosion resistance of metallic materials and coatings. The test involves subjecting a test specimen to continuous and controlled exposure to a salt spray mist, typically made up of a 5% sodium chloride solution, in a closed chamber for a specified period of time

ASTM B117 Salt Spray Test

Throughout their existence, several metals and coated metal goods are subjected to corrosive conditions. It is crucial to evaluate your product’s corrosion resistance using ASTM B117 salt spray testing as you do your research and plan your product’s design. In addition to our diverse range of physical testing services, Infinita Labs now offers salt spray tests. With capabilities like our B117 test labs for businesses and federal agencies across the nation, we are the industry leaders in standardized material testing.

The ASTM B117 Salt Spray Test: What Is It?

The ASTM B117 standard was created to provide specialists with instructions for conducting tests on coated metals’ and alloys’ resistance to corrosion brought on by seawater. Numerous businesses and even governmental bodies like the Department of Defense and the Department of Energy of the United States have adopted it as one of the most widely used procedures for salt spray testing. At Infinita Labs, we’ve spent more than 30 years providing salt spray testing to a range of industries, including the military, paints and coatings, automotive, and aerospace.

Procedure for Salt Spray Test

In ASTM B117 testing, samples are subjected to corrosion utilizing an environment that speeds up the passage of time and salt exposure. The pH of the solution and chamber temperature is normally held constant during the test. The length of the test will vary depending on the product, material, and planned application. Technicians can utilize test results and other data to assess the materials’ relative corrosion resistance when the testing apparatus continuously sprays salt water on the samples.

Your samples will be placed in one of our specialist chambers built to B117 criteria during the salt spray test. The ideal working temperature and fall-out rate are already set for this chamber, which is typically approximately 35 degrees Celsius. The test solution, which is typically produced by combining 5% sodium chloride and 95% water, will then be continuously sprayed by the machine. The pH of the fluid is kept neutral, ranging between 6.5 and 7.2.

After the material has been tested, we can visually inspect the specimen to determine its corrosion resistance. The final report will take into account the visual outcomes, any weight reduction or growth, and other similar aspects. We’ll explain the findings of your salt spray test in this report and show you how to apply them to the development, design, and manufacture of your products.
