## Abstract

The reference test method for salt-spray (fog) corrosion testing of coatings, including anodic coatings on aluminium. Specifies test chamber temperature (35 ± 1.1 °C), salt solution concentration (5 ± 1% NaCl), pH (6.5 to 7.2), and spray collection rate (1-2 mL/h per 80 cm² horizontal area). Test duration is specified by the product standard being verified — typical anodize targets are 336 hours for sealed Type II coatings and 500-1000+ hours for sealed hard anodize. The most-cited corrosion-resistance test method globally.
