Scope

This European Standard specifies a method for the determination of the content of quaternary ammonium surface active agents in raw materials and formulated products, defined as being the amount of quaternary ammonium surface active agents expressed in millimoles per 100 g of product. NOTE 1 The applicability in products different than those tested should be checked in each particular case. NOTE 2 In comparison to usual laboratory two-phase titration with visual endpoint determination (see ISO 2871-1 and ISO 2871-2) potentiometric titration offers the advantage of automation, operator-dependent differences in recognising the equivalence point can be neglected, and a non-critical solvent replaces the toxicologically critical chloroform.
