ASTM B117 – Salt Spray Test

The ASTM B117 Salt Spray Test is an important test for the construction industry. Building products such as cold-formed steel framing (studs and track), fasteners (nails and screws), and other metallic products with protective coatings are often required to be evaluated for corrosion resistance. Sometimes even plastic materials are tested.

ICC-ES is an accredited third-party testing service that can provide this test on a variety of products and materials used in the building and automotive industries.

While performing the ASTM B117 test, all test specimens are cleaned and then exposed to an atomized saltwater solution inside the enclosed chamber. The chamber maintains a temperature of 95°F with humidity approaching 100%. Throughout the exposure period, the salt spray is monitored for dispersion throughout the chamber as well as for concentration, temperature, and pH level of the solution.

ASTM B117 salt spray test itself does not set a required duration for exposure; other specifications or governing standards typically specify the number of hours. Alternatively, in the absence of a governing specification, the client may specify the duration.
