This test method is suitable for evaluation of materials and material proportions for construction purposes as well as for research and development.

This test method can be used to establish the correlation between indirect measures of the chloride-ion penetration of concrete (see Test Method C1202) and the actual chloride-ion penetration under controlled conditions.

This test method is not intended to provide a measure of the length of service that may be expected from use of a specific concrete mixture or sealing material.

If the purpose for testing is to determine the apparent chloride diffusion coefficient, it is recommended that Test Method C1556 be used.

1.1 This test method determines the penetration of chloride ion into concrete from a sodium-chloride solution pond. This method is applicable to all types of concrete, as well as to concretes treated with systems such as sealants, penetrating sealers, or thin-bonded overlays.

1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this 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.
