Salt Fog Test Lab

The salt spray test is a standardized test method (ASTM B117) used to check corrosion resistance of coated or non-coated metallic samples. Since coatings can provide a high corrosion resistance through the intended life of the part in use, it is necessary to check corrosion resistance at an accelerated rate.

Salt fog testing is an accelerated corrosion test that produces a corrosive attack to the coated samples in order to predict its suitability in use as a protective finish.

The appearance of corrosion products (oxides) or coating adhesion is evaluated after a period of time. Test duration depends on the corrosion resistance of the coating; the more corrosion resistant the coating is, the longer the period in testing without showing signs of corrosion.

Metallurgical offers numerous cabinets conforming to ASTM B117 in order to provide the most cost-effective test program to our clients. We typically start your test upon receipt and our depth of facilities allows us to accommodate samples of various sizes. We provide professional photography in order to document performance changes in your product.
