1.1 This test method describes a potentiometric titration procedure for the determination of quaternary ammonium salts in fabric softeners. This test method is intended for the analysis of known quaternary ammonium salts such as the dialkyl dimethyl quaternary ammonium compound type and the diamidoamine based quaternary ammonium compound type.

1.2 The quaternary ammonium salts conform to the structures shown in Fig.1 and Fig. 2.

1.3 The analytical procedure appears in the following order:

1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use.
