Abstract : In the evaluation of corrosion preventives the most critical analysis of any compound in this field is to determine its ability to protect. A current protection test employes the ASTM tentative Method D1748-62T. An improved version of this test method, the accelerated condensation apparatus (ACA) was studied. The improvement of its functional properties was investigated and recommended. Experimental results indicated a nylon cloth, selected from 14 types of fabric, showed positive improvement in the precision testing of the ACA. The study also uncovered several factors which affect the performance of the ACA. They are the test chamber temperature and the surface finish of the test specimen. Critical corrections for these factors were recommended to be incorporated into the standard test conditions for the ACA to provide optimum precision. (Author)
