Historical Standard: ASTM D5806-95(2003) Standard Test Method for Disinfectant Quaternary Ammonium Salts by Potentiometric Titration
SUPERSEDED (see Active link, below)
ASTM D5806
1. Scope
1.1 This test method covers a potentiometric titration procedure for determining active matter in disinfectant quaternary ammonium salts. This test method is intended for the analysis of quaternary ammonium salts used as disinfectants, and only applies to the following commonly used quaternary ammonium salts: n -alkyldimethylbenzylammonium chloride (see Fig. 1), cetyltrimethylammonium chloride, and a blend of n -octyldecyl dimethylammonium chloride, di- n -octyl dimethylammonium chloride, and di- n -decyldimethyl ammonium chloride (see Fig. 2). Also, this test method can be applied to the analysis of disinfectant type products where the formula ingredients are known and the quaternary ammonium salt is one of the above. Interferences such as amines oxides and betaines present in disinfectant formulations were not tested.
1.2 This disinfectant quaternary ammonium salt conforms to the structures in Fig. 1 and Fig. 2.
1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. For specific precautionary information, see Section 8.
