Salt Spray Corrosion Testing

Salt spray and salt fog are types of accelerated corrosion tests that are performed to assess the comparative corrosion resistance of certain materials when exposed to salt fog or salt spray at a specific temperature. In this test, specimens are put inside a chamber or cabinet for salt fog testing, with constant salt water spray or indirect fog, while the climate is maintained during the test. Salt fog is also known as the fog test or salt spray test.

This form of testing is only one form of corrosion testing which is designed to create a caustic environment for products to soak in for a specified amount of time (determined by any of several testing standards, or by specific manufacturer requirements).

Our Salt Spray Testing Services

Depending on the standard or test plan chosen, samples are exposed to the spray solution for a predetermined period of time and checked regularly throughout testing to evaluate the product.

Our most common applications requested are for spray testing and salt fog for coated or painted marine, automotive, and military equipment. We have extensive experience with MIL-STD salt spray testing as well as ASTM B117 and DO-160 testing standards.
