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.
