Salt Spray (Fog) Testing is conducted to evaluate the corrosion resistance of metallic materials, protective coatings, and surface treatments under accelerated chloride-rich environments. The test exposes specimens to a controlled salt fog atmosphere in accordance with recognized international standards, enabling assessment of coating durability, corrosion protection performance, and susceptibility to surface degradation. The evaluation includes examination of rust formation, blistering, coating breakdown, and other corrosion-related defects following exposure.
These tests are widely used for quality assurance, product qualification, and comparative performance assessment of materials and protective systems intended for industrial, marine, and corrosive service environments.
