This document specifies the performance requirements for fluxes in solid, liquid and paste forms intended for use with soft solders.
NOTE 1 ISO 9454-1 specifies the requirements for labelling and packaging as well as the coding system for the classification of the fluxes.
NOTE 2 Some of the fluxes intended for inert gas and vapour phase soldering may not pass some of the criteria in Tables 1 and 2.
Requirements for these fluxes are agreed between the purchaser and the supplier
