SHORT-TERM EVALUATION PROCEDURES FOR COATINGS ON STRUCTURAL STEEL

The objectives of the study are to review existing short-term test procedures for selecting coatings, and to discuss analytical measurement techniques for characterizing coating systems and for monitoring coating degradation. In assessing current accelerated aging testing procedures several deficiencies became apparent. These included the reported lack of reproducibility in the rankings for different iterations of the same short-term test and the lack of correlatability between the rankings of short-term laboratory and long-term outdoor exposure tests.
