BS EN ISO 9455-3:2020


This standard BS EN ISO 9455-3:2020 Soft soldering fluxes. Test methods is classified in these ICS categories:
  • 25.160.20 Welding consumables

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 endâ??point, titration method.
