ACCELERATED ENVIRONMENTAL TESTING: TECHNICAL REPORT NO. 2, GDOT RESEARCH PROJECT NO. 6301

THIS REPORT PROVIDES A DESCRIPTION OF THE DESIGN AND OPERATION OF AN ACCELERATED CORROSION ENVIRONMENTAL CHAMBER FOR METAL PROTECTIVE PAINTS AND A DISCUSSION OF THE FINDINGS OF EXPERIMENTS DESIGNED TO TEST THE REPRODUCIBILITY OF RESULTS IN THE CHAMBER AND LIMITED AVAILABLE DIRECT CORRELATIONS WITH DATA FROM AN EXTERIOR WEATHERING TEST FENCE AT A TIDAL ESTUARY IN BRUNSWICK, GEORGIA. THE MAJOR CONCLUSIONS REACHED WERE THAT THE ENVIRONMENTAL CHAMBER EXHIBITS HIGH PRECISION OF TEST RESULTS WITHIN RUNS AND AN EXCEPTIONALLY CLOSE SIMILITUDE IN A GREATLY ACCELERATED TEST TO THE MODES OF PANEL FAILURE OBSERVED IN THE FIELD. THE PROSPECTS FOR CLOSE LAB-FIELD CORRELATION APPEARED VERY GOOD, BUT, FOR GENERAL USE, SUCH CORRELATION WAS SEEN TO REQUIRE CONTROL SYSTEM TECHNIQUES WHICH HAVE BEEN PROPOSED BUT NOT YET VALIDATED WITH COMPREHENSIVE EXPERIENTAL STUDIES. /NTIS/
