Soft soldering fluxes - Test methods - Part 3 : determination of acid value, potentiometric and visual titration methods

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.
