Soft soldering fluxes. Test methods. Flux efficacy test, solder spread method | Status: Under review, Current

1 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]
