What is salt spray testing?

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. This accelerated process applies a 5% NaCl (sodium chloride) solution to coated or painted marine, automotive, and military equipment. For projects with specific requirements, we can adjust environmental conditions like temperature and humidity to simulate different climates or working conditions. Samples are checked regularly to monitor corrosion levels, noting milestones such as white and red rust development or coating degradation. Our labs provide detailed test reports with with before-and-after photographs, calibration data, time/date records, and Element's certifications.

What is the difference between salt spray and salt fog testing?

From a testing standpoint, salt fog testing and salt spray testing are the exact same test, with names often used interchangeably. These tests are often referred to by these different names because the levels of salt being applied vary accordingly to the specific environmental conditions needed to be replicated.

What are the outcomes of ASTM B117 testing? 

The test provides visual inspection results on corrosion resistance, coating adhesion (combined with ASTM D3359), and corrosion development from scratches (combined with ASTM D1654). Note: correlating results to real-world conditions is challenging.

When is it not recommended to use ASTM B117?

It is not recommended for products with decorative chromium plating, zinc die castings, or cadmium plating on steel. For these, consider ASTM B368 or Practice G85 instead.

What are the testing conditions for ASTM B117? 

The test is performed in chambers with a temperature of 35°C (+/- 2°C), neutral pH (6.5–7.2), and a salt concentration of 5% sodium chloride. Exposures are typically 96, 240, or 600 hours.

What should you ask before requesting an ASTM B117 test?

How many units will you test? How should the samples be oriented in the chamber? At what stages of corrosion should photographs be taken? Do you need post-test cleaning of the samples? Is ASTM B117 compliance mandatory for your product?
