ASTM B117-19: Standard Practice for Operating Salt Spray Tester

ASTM B117-19: Standard Practice for Operating Salt Spray (Mist) Devices provides guidelines for devices that help identify corrosion resistance information.

 

 

Corrosion is the decay of a material due to a chemical reaction with its environment. Total corrosion occurs when a large number of atoms on the surface of a metal are oxidized. The most common product of iron corrosion is rust. 

 

 

Corrosion can jeopardize human life. Many tragedies have occurred due to corrosion. For example, in 2017, a ride at the Ohio State Fair collapsed, killing one person and injuring seven others. The manufacturer cited corrosion as the reason for the ride's failure.In 1983, the Mianus River Bridge collapsed, killing three people and seriously injuring many others. The bridge was only 25 years old at the time. An investigation found corroded support pins on the bridge. 

 

The cost of corrosion can also be high. a study conducted by NACE International from 1999 to 2001 found that corrosion directly causes $276 billion in damage annually. This, of course, does not take into account the indirect costs of corrosion. According to the same NACE study, a conservative estimate of indirect costs totaled $552 billion. Clearly, corrosion needs to be considered.

 

 

ASTM B117-19 covers equipment, procedures, and guidelines for creating and maintaining salt spray (fog) test environments. Notably, the standard does not prescribe interpretation of results. It also does not specify exposure times to be used for specific products or types of test specimens. 

 

ASTM B117-19 provides a controlled corrosion environment that can be used to collect information on the relative corrosion resistance of metal samples and coated metals exposed in a stationary test chamber.
