Soft soldering fluxes - Classification and requirements - Part 2: Performance requirements (ISO 9454-2:2020)
This document specifies the performance requirements for fluxes in solid, liquid and paste forms
intended for use with soft solders.
NOTE 1 ISO 9454-1 specifies the requirements for labelling and packaging as well as the coding system for the
classification of the fluxes.
NOTE 2 Some of the fluxes intended for inert gas and vapour phase soldering may not pass some of the criteria
in Tables 1 and 2.
Requirements for these fluxes are agreed between the purchaser and the supplier.
Flussmittel zum Weichlöten - Einteilung und Anforderungen - Teil 2: Eignungsanforderungen (ISO 9454-2:2020)
Dieses Dokument legt die Eignungsanforderungen für Flussmittel in fester, flüssiger und pastöser Form, die zum Weichlöten verwendet werden, fest.
ANMERKUNG 1 ISO 9454 1 legt die Anforderungen für Kennzeichnung und Verpackung sowie ein Kurzzeichen-System zur Einteilung der Flussmittel fest.
ANMERKUNG 2 Einige Flussmittel zum Schutzgas- und Dampf-Phase-Löten können u. U. einige der Kriterien in Tabelle 1 und Tabelle 2 nicht erfüllen.
Die Anforderungen für diese Flussmittel werden zwischen dem Käufer und dem Lieferanten abgestimmt.
Flux de brasage tendre - Classification et exigences - Partie 2: Exigences de performance (ISO 9454-2:2020)
Le présent ducument fixe les exigences de performance pour les flux solides, liquides ou en pâte, destinés à être utilisés avec des métaux d'apport de brasage tendre.
NOTE 1 L'ISO 9454‑1 fixe les spécifications relatives au marquage et à l'emballage ainsi que le système de codification pour la classification des flux.
NOTE 2 Certains flux destinés au brasage tendre en atmosphère inerte et au brasage tendre en phase vapeur peuvent ne pas répondre aux critères indiqués dans les Tableaux 1 et 2.
Il est recommandé que les exigences relatives à ces flux fassent l'objet d'un accord entre l'acheteur et le fournisseur

Introduction
Fluxes assist molten solder to wet metals surfaces to be joined by removing oxides and related
contaminants from the solder and surfaces of the parts during soldering. Fluxes also protect surfaces
from oxidization and assist wetting of the base metals by molten solder.
Care is necessary when selecting a flux for a particular application, in order to ensure an adequate
service life of the assembly. Factors such as the ease of residue removal, corrosiveness, possible health
and safety hazards and the efficacy of the flux, should all be considered when making the choice.
