Soft soldering fluxes - Test methods - Part 17: Surface insulation resistance comb test and electrochemical migration test of flux residues (ISO 9455-17:2024)

This document specifies a method of testing for deleterious effects that can arise from flux residues after soldering or tinning test coupons. The test is applicable to type 1 and type 2 fluxes, as specified in ISO 9454-1, in solid or liquid form, or in the form of flux-cored solder wire, solder preforms or solder paste constituted with eutectic or near-eutectic tin/lead (Sn/Pb) or Sn95,5Ag3Cu0,5 or other lead-free solders as agreed between user and supplier (see ISO 9453).
This test method is also applicable to fluxes for use with lead-containing and lead-free solders. However, the soldering temperatures can be adjusted with agreement between tester and customer.

Flussmittel zum Weichlöten - Prüfverfahren - Teil 17: Bestimmung des Widerstandes der Oberflächenisolierung, Kammprüfung und elektrochemische Migrationsprüfung von Flussmittelrückständen (ISO 9455-17:2024)

Dieses Dokument legt ein Prüfverfahren zur Ermittlung von Schädigungen, die durch Flussmittelrückstände nach dem Weichlöten oder nach dem Verzinnen von Proben entstehen können, fest. Die Prüfung ist anwendbar für Flussmittel der Typen 1 und 2 nach ISO 9454 1 in fester oder flüssiger Form, in Lotdrähten, Lotformteilen oder Lotpasten in Verbindung mit eutektischem oder nahezu eutektischem Zinn/Blei (Sn/Pb) oder Sn95,5Ag3Cu0,5 oder anderen bleifreien Loten, wie zwischen Anwender und Lieferant vereinbart (siehe ISO 9453).
Dieses Prüfverfahren ist auch anwendbar für Flussmittel beim Einsatz von bleihaltigen und bleifreien Loten. Die Löttemperaturen können jedoch zwischen dem Kunden und dem Prüfer abgestimmt werden.

Flux de brasage tendre - Méthodes d'essai - Partie 17: Essai au peigne et essai de migration électrochimique de résistance d'isolement de surface des résidus de flux (ISO 9455-17:2024)

Le présent document spécifie une méthode d'essai relative aux éventuels effets néfastes des résidus de flux après brasage tendre ou étamage de coupons d'essai. L'essai est applicable aux flux de type 1 et de type 2, tels que spécifiés dans l'ISO 9454-1, sous forme solide ou liquide, ou sous forme de fil d'apport à flux incorporé, de préformes ou de crème à braser constitués de métal d'apport étain/plomb (Sn/Pb) ou Sn95,5Ag3Cu0,5 ou autres métaux d'apport de brasage tendre sans plomb comme convenu entre l'utilisateur et le fournisseur (voir l’ISO 9453).
Cette méthode d'essai est également applicable aux flux à utiliser avec des métaux d'apport de brasage tendre contenant ou non du plomb. Toutefois, les températures de brasage peuvent être convenues entre le responsable de l'essai et le client.

Talila za mehko spajkanje - Preskusne metode - 17. del: Preskus odpornosti površine izolacije z glavnikom in preskus elektrokemičnega prenosa talila (ISO 9455-17:2024)

Ta dokument določa preskusno metodo za škodljive učinke, ki lahko nastanejo zaradi talil po spajkanju ali kositranja preskusnih kuponov. Ta preskus se uporablja za talila tipa 1 in tipa 2, kot je določeno v standardu ISO 9454-1, v trdni ali tekoči obliki, ali v obliki varilne žice s talilnim jedrom ali paste za spajkanje, ki jo sestavljajo evtektične ali skoraj evtektične kositrne/svinčene (Sn/PB), Sn95,5Ag3Cu0,5 ali druge nesvinčene spajke, kot se dogovorita uporabnik in dobavitelj (glej tudi standard ISO 9453).
Ta preskusna metoda se prav tako uporablja za talila za uporabo s spajkami s svincem ali brez njega. Vseeno je mogoče temperature spajkanja prilagoditi ob dogovoru med preskuševalcem in stranko.
