Let us analyze the test report :
1, The test condition: Salt solution: 5% NaCl, (more than seawater 1%-3.5%），
2, Test duration: 72 hours, As it is an accelerated corrosion test, testing 72 hours in the chamber means that testing the sample 3 years in the natural environment.
3, Performance rating:
If the defect area is less than 0.1%, the Rp/Ra is 9.
If the defect area is 0.1%-0.25%, the Rp/Ra is 8.
4, Rating of types of coating deterioration:
5, Result:
After the test, the results are that the corrosion Performance rating (Rp/Ra) is 9 or 8 and vs E.
It means the defect area is only less than 0.25%, a very slight amount of surface pitting for the surface of street lights.
For the screw, no defect, no corrosion.
So we think that the result is positive and good.
