1.1 This test method covers the laboratory determination of the chloride-ion threshold for corrosion of reinforcing steel in concrete. 1.2 UnitsThe values stated in either SI units or inch-pound units are to be regarded separately as the standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in nonconformance with the standard. 1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
The chloride value at which corrosion initiates for steel in concrete is critical in determining the service life of concrete structures. As of now there is no standard method for determining this value which is used in various service life modeling programs.
