Brasage fort - Flux pour le brasage fort - Classification et conditions techniques de livraison (ISO 18496:2020)

Le présent document établit la classification des flux utilisés pour le brasage fort des métaux et caractérise ces flux d’après leurs propriétés et leurs applications, et donne des recommandations relatives aux conditions techniques de livraison et à l’hygiène et à la sécurité.
Le présent document définit deux classes de flux, FH et FL. La classe FH est utilisée pour le brasage fort des métaux lourds (les aciers ordinaires, les aciers inoxydables, le cuivre et ses alliages, le nickel et ses alliages, les métaux précieux, le molybdène et le tungstène). La classe FL est utilisée pour le brasage de l’aluminium et de ses alliages.

Trdo spajkanje - Talila za trdo spajkanje - Razvrstitev in tehnični dobavni pogoji (ISO 18496:2020)

Brazing — Fluxes for brazing — Classification and
technical delivery conditions
1 Scope
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.
2 Normative references
There are no normative references in this document.
3 Terms and definitions
No terms and definitions are listed in this document.
ISO and IEC maintain terminological databases for use in standardization at the following addresses:
— ISO Online browsing platform: available at https:// www .iso .org/ obp
— IEC Electropedia: available at http:// www .electropedia .org/
4 Classification
4.1 General
The form of the fluxes shall be classified according to Table 1 A, B or C. The effective temperature range
can be determined according to Annex A.
4.2 Fluxes for brazing heavy metals (Class FH)
4.2.1 General
Class FH covers nine types of flux. The code for each type consists of the class letters FH followed by
two digits.
4.2.2 Type FH10
Fluxes with an effective temperature range from about 550 °C up to about 800 °C. They contain boron
compounds, simple and complex fluorides and are used at brazing temperatures above 600 °C. These
are general purpose fluxes. The residues are usually corrosive and have to be removed by washing or
pickling.
4.2.3 Type FH11
Fluxes with an effective temperature range from about 550 °C up to about 800 °C. They contain boron
compounds, simple and complex fluorides and chlorides and are used at brazing temperatures above
