What is Salt Spray Testing?
The salt spray test — also known as the salt fog test — is a standardized, widely used corrosion test method used to check the corrosion resistance of materials and surface coatings. The materials tested are usually metallic, although stone, ceramics, and polymers may also be evaluated, finished with a surface coating intended to provide a degree of corrosion protection to the underlying metal.
Salt spray testing is an accelerated corrosion test that produces a corrosive attack on coated samples in order to evaluate — mostly comparatively — the suitability of a coating for use as a protective finish. The appearance of corrosion products (rust or other oxides) is evaluated after a pre-determined period of time; the more corrosion-resistant a coating is, the longer the testing period before corrosion or rust appears.
The salt spray test is one of the most widespread and long-established corrosion tests in the industry. ASTM B117 was the first internationally recognized salt spray standard, originally published in 1939. Other important relevant standards include ISO 9227, JIS Z 2371, and ASTM G85 — all of which UNICO's coating systems are tested and validated against.
