    Abstract

    This method covers a procedure, known as the NDHA method, for studying the corrosivity of waters. It is particularly applicable to waters relatively free of suspended materials at temperatures below 200 C and at flow rates below 5 ft per sec, and has had extensive use for determining corrosion by steam condensate. N 1.—This method conforms to the general requirements for conducting plant tests given in the Recommended Practice for Conducting Plant Corrosion Tests (ASTM Designation: A 224). N 2.—The prime purpose of the test is to investigate the corrosive characteristics of waters in the equipment in which the test is made. It may fail to indicate the corrosive characteristics of the same water in different equipment. Results may be used also to indicate the ability of the materials tested to withstand corrosion by the water.
