GB/T 31820-2015 "Paints for Cargo Oil Tanks of Crude Oil Tankers" is applicable to coatings used for the protection of the inner walls of cargo oil tanks in crude oil tankers, focusing on key properties such as resistance to crude oil corrosion and adhesion. The corrosion resistance is tested using a salt spray test chamber and a crude oil immersion test device, the coating bond strength is determined using a pull-off adhesion tester, and the construction viscosity is controlled with a viscometer. The standard specifies coating thickness, drying conditions, and inspection rules to ensure that the coatings meet the requirements of the specific media and working conditions in cargo oil tanks.
