ASTM B117: Standard to Test Corrosion on Coated Metals

What is Corrosion?
Corrosion is a process that transforms a refined metal or a coated metal into a chemical oxide which leads to a gradual destruction of metals Generally, corrosion occurs due to many environmental factors such as rain, wind, moisture, fog, etc.

Now the question is, how can the corrosion resistance strength of a metal be tested?

Well… there are many standards that are defined to test the corrosion resistance strength of a plated metal in Paint & Automotive industries such as ASTM B117, ISO 9227, and JIS Z 2371.

Out of the all, ASTM B117, is the popular standard designed to provide corrosion resistance information on coated metals. The test standard is also approved for use by Department of Defense agencies.

What does the standard say?
ASTM B117 defines the salt fog or salt spray testing procedure. The standard is designed to gauge the corrosion resistance strength of a metal and coated metals.

Now, you might be wondering how much time it requires to perform a salt spray test and how it can be performed.

The best testing equipment to perform the salt spray test is the Salt Spray Chamber.

Also known as Corrosion test chamber, the equipment is widely used to evaluate the corrosion resistance strength of products. It is the best testing machine that helps to measure the corrosion resistance of different types of coatings. Using the equipment, artificial environmental conditions are created inside the chamber, to give direct exposure of different weather conditions such as fog, mist, rain, etc. to the coated metals in order to assess their longevity and quality.

The salt spray test majorly helps paint and plating industries and automotive component manufacturers to assess the quality of the samples developed in their premises.

The test duration is examined based on the life of a product. For example, if a product is tested in a natural environment and observed that it will take 1 year to get corroded, a Salt spray chamber will take 24 hours to obtain the same results.

So, with the help of a Salt Spray Fog Chamber, one can calculate the corrosive strength of the sample and the estimated life that a customer can receive.
