Soft soldering fluxes. Test methods - Flux efficacy test, solder spread method Ingestion-build-50790 whether they are conducting or1 Scope This part of ISO 9455 specifies a method for the determination of the efficacy of a soft soldering flux. The method is known as the solder spread method of filler metal and is applicable to all flux classes defined in ISO 9454 1. NOTE An alternative method for the determination of the flux efficacy, applicable to liquid fluxes only, known as the wetting balance method, is specified in ISO 9455 16.[3]
