A salt spray test is a corrosion testing method 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.

Salt Spray Testing
ASTM B117 Salt Spray, Salt Fog and Corrosion Testing
Element provides ASTM B117 salt spray, salt fog testing as a rapid method to evaluate the corrosion resistance of your material, surface or coating.
The ASTM B117 test method involves creating a controlled accelerated corrosive environment in a salt spray cabinet or chamber to determine the effects of corrosion on a test specimen.
At Element, our high-capacity salt spray testing labs can test a number of test specimens of many sizes, shapes and dimensions for the ASTM B117 Salt Spray Test. We can also accommodate the duration of the exposure for the test according to specific to customers’ requirements. Our Engaged Experts provide a thorough report with test data, pictures and discussions to help you understand your test results.
With a global platform of ISO 17025 and NADCAP accredited laboratories in the United States, UK, Europe and Asia, Element offers ASTM B117 salt spray and salt fog testing to support a wide range of regulatory standards and testing requirements in many industries including Oil & Gas, Aerospace, Military and Automotive industries.

Alternative salt spray test conditions
Alternative salt spray testing can simulate a variety of corrosive environments to ensure the integrity of a product.
When routine testing isn’t enough, Element offers alternative salt spray test methods to cover a variety of conditions. For large or unusually shaped components, our largest chamber is 8’H x 8’W x 10’L, and can reach temperatures of up to 55°C.
Some of our capabilities include:
- Neutral salt spray (NSS)
- Acetic acid salt spray (ASS)
- Copper-accelerated acetic acid salt spray (CASS)
- Calcium chloride (CaCl₂)
- Synthetic seawater testing
- Hydrogen induced cracking (HIC)
- Custom cyclic corrosion testing
