Note:

Salt Spray Test(SST):

Test condition: 5%NaCl, 35℃, Continuously spray a certain time, test whether there is corrosion on coating surface.

3.Pressure Cooking Test(PCT):

Test conditions : 2 atm, 95% RH(relative humidity), 121 ℃

Purpose: Test the coating adhesion.

Notes: The products coating Zinc,passivation/phosphated, or coating Epoxy are not suitable for PCT.

4.Other methods to test the coating quality: Drop test, Cross Cut test,Heating and Spilling Test ,the constant temperature and humidity test etc.
