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.
Abstract
Overview
ISO 9455-3:2019 is an internationally recognized standard that specifies test methods for determining the acid value of soft soldering fluxes, specifically types 1 and 2 as defined in . The standard presents two methods for measuring the acid value:
