It is not applicable to other basic substances.2 Normative referenceThis European Standard incorporates by dated or undated reference, provisions from other publications. Thesenormative references are cited at the appropriate places in the text, and the publications are listed hereafter. Fordated references, subsequent amendments to or revisions of any of these publications apply to this EuropeanStandard only when incorporated in it by amendment or revision. For undated references the latest edition of thepublication referred to applies (including amendments).ISO 607, Surface active agents and detergents — Methods of sample division.3 PrincipleThe sum of amide nitrogen and amine nitrogen as well as soap are determined by potentiometric titration of the testsample, dissolved in acetic acid anhydride, with standard trifluoromethane sulfonic acid solution. The content ofamine nitrogen as well as soap are determined by potentiometric titration of the test sample, dissolved in glacialacetic acid, with trifluoromethane sulfonic acid standard volumetric solution. From the difference between the twotitrations, the amide nitrogen content in grams per 100 g is calculated.4 ReagentsDuring the analysis, unless otherwise specified, use only reagents of recognized analytical grade and have beenchecked in advance as to not interfere with the analytical results.4.1Glacial acetic acid, purity 100 %.4.2Acetic acid anhydride, purity 98,5 % (minimum).4.3Trifluoromethane sulfonic acid standard volumetric solution, c (HSO3CF3) = 0,1 mol/l, in aceticacid (4.1).NOTEPerchloric acid
