This document specifies the procedure for obtaining the non-steady-state chloride migration coefficient
of specimens of hardened concrete at a specified age (see Annex A). The test procedure does not take
into account any interaction of concrete with the saline solution over time. The test result is a durability
indicator with respect to the resistance of the concrete investigated against chloride penetration.
The test procedure does not apply to concrete specimens with surface treatments such as silanes.
If the aggregate or any other embedded elements (such as metallic fibres or conducting particles) are
electrically conductive, this will influence the magnitude of chloride migration. This fact is taken into
account when establishing threshold values. It prevents comparison of chloride migration values
between concretes if the aggregates induce a difference of half an order of magnitude (higher or lower)
of chloride migration.
