DIN EN ISO 2871-2
Surface active agents - Detergents - Determination of cationic-active matter content - Part 2: Cationic-active matter of low molecular mass (between 200 and 500) (ISO 2871-2:2010); German version EN ISO 2871-2:2010

Title (German)

Tenside - Waschmittel - Bestimmung des Gehaltes der kationaktiven Substanz - Teil 2: Kationaktive Substanz niedriger Molmasse (zwischen 200 und 500) (ISO 2871-2:2010); Deutsche Fassung EN ISO 2871-2:2010

Overview

This standard specifies a method for the determination of low-molecular-mass cationic-active matter such as monoamines, amine oxides, quaternary ammonium compounds and alkylpyridinium salts which have a main chain of 10 to 22 carbon atoms and not more than 6 other carbon atoms in the cation. The specified method is applicable to solids or to aqueous solutions of the active material when the relative molecular mass of the cationic-active matter is known or when it has been previously determined, if its content is expressed as a percentage by mass. If more than one type of cationic-active matter is present, an estimate of average relative molecular mass may be used. The method is not applicable if anionic and/or amphoteric surface active agents are present. The standard EN ISO 2781-2 has been prepared by Technical Committee ISO/TC 91 "Surface active agents" (secretariat: ISIRI, Iran), in collaboration with Technical Committee CEN/TC 276 "Surface active agents" (secretariat: AFNOR, France). The responsible German Committee is Working Committee NA 062-05-62 AA "Analytik von Tensiden" ("Analytics of surfactants") of NMP.
