GB/T 6824-1986 "Determination of copper ion exudation rate in real sea of anti-fouling paint on the bottom of a ship" is a national standard, which stipulates the determination method of copper ion exudation rate of anti-fouling paint on the bottom of a ship in a real marine environment. The standard covers the test design of real sea hanging plates, including sample preparation (test plates for painting anti-fouling paint), installation of hanging plate devices, setting of seawater soaking cycle, testing the copper Ion concentration in seawater solution in different time periods by chemical analysis and other methods, and calculating the exudation rate per unit area. This method is suitable for evaluating the performance of anti-fouling paint in inhibiting marine biological adhesion by releasing copper ions, providing a quantitative detection basis for the environmental friendliness, effectiveness and long-term effectiveness of marine anti-fouling coatings, and helping to standardize the quality control and performance evaluation of marine anti-fouling paints.
