This European Standard is a method for determining the unidirectional apparent chloride
diffusion coefficient and surface concentration of conditioned specimens of hardened concrete.
The test method enables the determination of the chloride penetration after a specified length of
curing and length of exposure to NaCl solution.
Since resistance to chloride penetration depends on the ageing, including the effects of continual
hydration and interactions with the chloride solution, then the apparent diffusion coefficient will
also change with age. A procedure to determine this ageing, expressed here by an ageing
exponent, is included in the standard and described in an annex.
The test procedure does not apply to concrete with surface treatments such as silanes and it
may not apply to concrete containing fibres
