509,2-5 509.2-8 509.2-10 509.2-11 SECTION I I-1 M.EEQSE. Salt fog climatic chamber tests are performed to determine the resistance of equipment to the effects of an aqueous salt atmosphere. 1-2. ~. The effects of exposure of materiel to an environment where there is an aqueous salt atmosphere can be divided into three broad categories: corrosion effects, electrical effects, and physical effects. I-2.1 ~ a. Corrosion due to electrochemical’reaction. b. Accelerated etress corrosion. c. Formation of acidic/alkaline solutions following salt ionization in water. I-2.2 ~ a. Impairment of electrical equipment due to salt deposits. b. Production of conductive coatinga. \ c.
