Soft soldering fluxes. Classification and requirements - Performance requirementsBS EN ISO 9454 2: 2001 specifies the performance requirements for fluxes in solid, liquid and paste forms intended for use with soft solders. Fluxes assist molten solder to wet metals surfaces to be joined by removing oxides and related contaminants from the solder and surfaces of the parts during soldering. Fluxes also protect surfaces from oxidization and assist wetting of the base metals by molten solder. Care is necessary when selecting a flux for
