The salt spray test is a popular method used for testing the corrosion resistance of surface coatings and materials. Salt spray testing produces an accelerated corrosive attack to evaluate the suitability of finishes and coatings. The duration of the test depends on the corrosion resistance of the material. Materials which are more resistant to corrosion will take longer to see the appearance of oxides or rust. The salt spray test was originally published in 1939 under ASTM B117 and is also covered in other standards such as ASTM G85, JUS Z 2371 and ISO 9227:2017.
Stucchi offers the A-ZN, with zinc plating for high corrosion resistance, designed to exceed the salt spray test.
