American Society for Testing and Materials (ASTM). Current edition approved July 1, 2005. Published August 2005. Originally approved in 1991. Last previous edition approved in 1997 as C 1202 – 97. 6 p. This test method covers the determination of the electrical conductance of concrete to provide a rapid indication of its resistance to the penetration of chloride ions. This test method is applicable to types of concrete where correlations have been established between this test procedure and longterm chloride ponding procedures such as those described in AASHTO T
259. Examples of such correlations are discussed in Refs 1-5.
