Atmospheric Exposed Test vs. Simulated Acceleration Test on Painted Test Piece
In cooperation with test equipment and paint manufacturers, as well as other companies and associations involved in the handling of anti-corrosive agents, we at the Public Works Research Institute, Ministry of Construction, have developed and put into trial use an apparatus which simulates environmental conditions for the purpose of testing at an accelerated rate the durability of anti-corrosive products used on steel structures in coastal areas. The apparatus is so built that environmental conditions such as light, salinity, the presence of acidic gas, humidity and temperature can be controlled at will, the test pieces being subjected to these simulated conditions in cycles which can be repeated at pre-determined intervals. Since 1979, we have been conducting simulated acceleration tests to investigate the durability of corrosion protective paints. In this report, we would like to discuss some of the findings which these tests have yielded. This research was conducted jointly by the Public Works Research Institute, Ministry of Construction, the Public Works Research Center, and the Japan Steel Bridge Paint Specialists Association. Research planning and the compilation of the research results were executed by the Committee for Research on Simulated Acceleration Testing of Corrosion Protective Materials, set up internally in the center and chaired by Dr. Harumitsu Tamano.
