Remarks The norm describes two procedures for determination of the total of (free and bound) acid-soluble chloride in hardened concrete and hardened cement. This information is provided for the assessment of the danger of steel reinforcement corrosion by chloride. The procedure can be carried out on powder samples gained from concrete structures by drilling or from drill corn samples or from fragments or from other suitable laboratory test items. Mortar prisms are made available according to EN 196-1. The traditional determination of loss of ignition through annealing in air in oxidizing atmosphere can be applied for the determination of loss of ignition and the “observed” loss of ignition as well. In case of oxidable substances especially sulfide or sulfurous substances the “observed” loss of ignition can be corrected to derive a “corrected” annealing loss for the summation of the oxide analyze. All mistakes due to oxidation of metallic iron, bivalent iron or bivalent manganese are normally considered to be negligible and only the corrected value is used for the correction for the extent of sulfide oxidation. The procedure is applied for both standard cements and for other cements and materials that are listed in the corresponding international standard.
