TESTING RESULT

The Simulation of Real World - Cyclical Seawater Immersion for 180 Days Corrosion Results (Cyclic Corrosion Testing)
The Test Results for 180 Days Seawater Immersion Corrosivity (Phase 2)
The Self-Drilling Screws Test Results for 180 Days Seawater Immersion Corrosivity  
Test Start Date At 3:00 on September 24th, 2015  
Sample QTY 5 Pieces/Per Different Self-Drilling Screw  
Test Cycle Time Per Stage (Phase 1) (Initial Period): 7 days’ immersion in seawater, and then another 3 days’ exposure to the sun (till 4th October, 2015).
(Midterm): 2 days’ exposure to the sun after 3 days’ soaking in seawater, and this cycle was to repeat 4 times. )
(Final): 3 days’ exposure to the sun after 7 days’ soaking in seawater. The test ends at this stage.
 
Test Cycle Time Per Stage (Phase 2) The self-drilling screws continued to be soaked when the phase 1 is completed.
The cycle time for the Phase 2:
7 days’ exposure to the sun after 30 days’ soaking in seawater, and this cycle was to repeat again and again.
 
Total Test Cycle Time 180 Days (From 2015/9/24 till 2016/3/21)
