The invention relates to a test method for accelerating reproduction of the salt spray corrosion pulverization effect of binding posts of an electric energy meter. The method comprises the following steps of: step 1, spraying salt spray to the binding post of the electric energy meter in a standard neutral salt spray test box, and continuously spraying the salt spray for 4 hours; 2, after finishing spraying, transferring the binding post of the electric energy meter into a damp-heat test box, and duration time being 20 h; 3, keeping the binding post of the electric energy meter in the damp-heat test box, and converting from a low-temperature and high-humidity damp stage to a high-temperature and low-humidity drying stage for 4 hours; step 4, maintaining a drying stage, and continuing the drying stage for 48 hours; and 5, repeating the steps 1-4 until a corrosion form distribution type and a corrosion area proportion are close to the actual corrosion form distribution type and corrosionarea proportion.
