prEN ISO 9455-8

This document specifies a method for the determination of the zinc content of water soluble fluxes of type 3, as defined in ISO 9454-1 [1]. The method is intended to apply to an aqueous solution of flux containing approximately 25 % of zinc, expressed as zinc chloride (ZnCI₂). For solid fluxes and for solutions whose concentrations differ appreciably from those stated above, an appropriate adjustment needs to be made to the amount of sample taken for the test.
