Soft soldering fluxes - Test methods - Part 3: Determination of acid value, potentiometric and visual titration methods (ISO 9455-3:2019)
This 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 an alternative, visual end‑point, titration method.
