ASTM B117 Salt Spray Test
Many metal and coated metal products are exposed to corrosive environments throughout their lifetime. As you conduct research and prepare your product's design, testing its resistance to corrosion through ASTM B117 salt spray testing is essential. VTEC Laboratories offers salt spray tests as part of our extensive physical testing abilities. We lead the way in standardized material testing with capabilities like our B117 test labs for businesses and federal agencies across the country.
Understanding ASTM B117 and Its Importance in Corrosion Resistance Testing
A better understanding of the ASTM B117 standards and their significance can help you make more informed decisions about your metal and coated metal components.
What Are ASTM B117 Standards for Salt Spray Fog Testing?
The ASTM B117 standard was designed to guide technicians in testing coated metals' and alloys' resistance to the corrosion caused by salt water. It's one of the most commonly recognized practices for salt spray testing, adopted by numerous companies and even government organizations, like the United States Department of Defense and the Department of Energy. At VTEC, we've provided salt spray testing to diverse industries — including military, paints and coatings, automotive and aerospace — for more than 30 years.
In ASTM B117 testing, specimens are exposed to corrosion using a chamber that accelerates time and salt exposure. The chamber's temperature and the solution's pH levels typically remain the same throughout the test. The test's length depends on factors like the given material, product and intended use. When the testing apparatus exposes the materials to continual salt spray, technicians can use the test information and other factors to determine their relative corrosion resistance, supporting products that meet durability and safety requirements.
Comparing ASTM B117 to Other Corrosion Standards
ASTM B117 slightly differs from some other widely recognized corrosion testing standards, like ISO 9227 and ASTM G85.
The primary difference between ASTM B117 and ISO 9227 is their acceptance. The ISO 9227 standard is accepted worldwide, while ASTM B117 applies only in the U.S. They generally use the same testing methods.
ASTM G85 is a modified version of ASTM B117. It can be useful when a different testing approach or more corrosive environment is necessary for the application.
It's crucial to pursue the right standard for your corrosion testing needs. Doing so helps ensure your products meet applicable safety regulations and performance expectations.
ASTM B117 Salt Spray Test: Procedure and Compliance for Your Products
ASTM B117 establishes the scope, apparatus and testing conditions required to achieve compliance.
What Are the Conditions for ASTM B117?
During the salt spray test, we'll place your specimens in one of our specialized chambers designed to B117 specifications. This chamber is pre-prepared to the optimal operating temperature — usually around 35 degrees Celsius — and rate of fallout.
The machine will then continually spray the test solution, which usually combines 5% sodium chloride and 95% water. The solution's pH is maintained at a neutral level between 6.5 and 7.2.
How Can You Meet the Standard?
Working with an accredited partner like VTEC helps ensure your products are ready for their intended environments and comply with the guidelines. We offer more than three decades of experience serving customers nationwide using state-of-the-art equipment run by a qualified team. Our services are cost-effective for even small startup companies while remaining high-quality and compliant with oversight bodies like the ISO and ASTM.
Further, we offer fast turnaround times that accommodate even tight deadlines, keeping your projects on schedule. We will have your results ready within two weeks of your test's completion and can even rush your results sooner if needed.
How to Interpret ASTM B117 Testing Results for Better Product Development
The results from our accredited ASTM B117 testing services provide organizational value when accurately analyzed and applied.
Analyzing Salt Spray Test Results
After testing the material, we can measure its corrosion resistance by visually examining the specimen. Our resulting report will consider the visual results, any weight loss or gain and similar factors. With this report, we'll help you understand the results of your salt spray test and how you can use them throughout your products' research, design and manufacturing.
Applying Test Results for Improvement
A detailed analysis allows you to compare results across key factors, such as materials and exposure time. That information helps you identify which metals or coatings best meet your longevity and safety goals. You can leverage the knowledge to improve your product design and performance, gaining or maintaining a competitive edge.

1. How Long Does the Test Take?
The duration of a salt spray test can vary. The overall ASTM B117 standard doesn't define a time frame, but other guidelines may designate a certain period of exposure required to meet a specific evaluation.
For example, the Steel Framing Industry Association mandates that structural components with nonstandard coatings undergo a minimum of 72 hours of ASTM B117 testing to meet their industry compliance code.
2. What Industries Use ASTMB117 Testing?
Many industries require and benefit from ASTM B117 testing, including:
- Aerospace and aircraft.
- Automotive manufacturing.
- Construction and building materials.
- Infrastructure, such as water and sewer pipes.
