适用范围：This European Standard specifies the Karl Fischer method using electrometric end point detection for the determination of the water content of surface active agents. The method is applicable to products in form of powders, pastes and solutions. The following substances interfere with Karl Fischer reagent: alkali metal silicates, carbonates; hydroxides and borates; oxidizing agents, ketones, aldehydes; strong mineral acids and strong bases. Samples that contain any of these substances cannot be measured directly by this present method; in those situations the solvent system and/or the Karl Fischer reagent have to be modified, but these modifications are out of the scope of this European Standard.
