The salt spray test result of LED lighting

Let us analyze the test report :

1, The test condition : Salt solution: 5% NaCl, (more than sea water 1%-3.5%），

2, Test duration : 72 hours, As it is accelerated corrosion test, so test 72 hours in chamber is means that test the sample 3 years in the natural environment.

3, Performance rating:

If the defect area is less 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 is that corrosion Performance rating (Rp/Ra) is 9 or 8 and vs E.

It mean the defect area only less 0.25%, very slight amount surface pitting for the surface of street light.

For the screw, no defect, no corrosion.

So we think that the result is positive, and good.
