DIN EN ISO 9455-3:1994 Soft soldering fluxes - Test methods - Part 3: Determination of acid value, potentiometric and visual titration methods (ISO 9455-3:1992); German version EN ISO 9455-3:1994
The document specifies two methods for the determination of the acid value of a flux of types 1 and 2 only, as defined in ISO 9454-1. Method A is a potentiometric titration method and is to be considered as the reference method. Method B is a alternative, visual end-point titration method.
