Dear Wa Sun Tech: |
The LaQue Center has completed a 240-hour salt spray test on five (5) specimens. The specimens, supplied and identified by you, were received on June 17, 2002. The test was conducted in accordance with the ASTM B-117 Standard Practice for Operating Salt Spray (Fog) Apparatus. Table I summarizes conditions within the exposure cabinet during the test period. Panels were inspected for signs of corrosion initiation after 5-hours of testing, thereafter when the cabinet was opened for condensate analysis. If corrosion was noted on the bold surface the specimen was removed from test. Table II shows the removal time for each panel. |
