Preparation of copper accelerated acetic acid/salt mist solution for salt spray tester *Step, the analytically pure sodium chloride solution should be in accordance with GB6682XX water at a concentration of (50±10) g/L.
In the second step, reagent grade copper chloride was added to 3.8 liters of brine for dissolution and thorough mixing.
In the third step, the pH of the solution was adjusted with acetic acid to a value in the range of 3.1 to 3.2, which was measured using the collected salt spray sample. The pH should be measured at 25 ° C. The prepared solution should be filtered before use.
