This document specifies the classification of fluxes used for brazing metals and characterizes these fluxes on the basis of their properties and use, and gives technical delivery conditions and health and safety precautions.
This document covers two classes of flux, FH and FL. Class FH is used for the brazing of heavy metals (steels, stainless steels, copper and its alloys, nickel and its alloys, precious metals, molybdenum and tungsten). Class FL is used for the brazing of aluminium and its alloys.st edition 2020-09 Brazing — Fluxes for brazing — Classification and technical delivery conditions Brasage fort — Flux pour le brasage fort — Classification et conditions techniques de livraison Reference number ISO 18496:2020(E) ？ ISO 2020 ISO 18496:2020(E) COPYRIGHT PROTECTED DOCUMENT ？ ISO 2020 All rights reserved.
