Soft soldering fluxes — Test methods — Part 17: Surface insulation resistance comb test and electrochemical migration test of flux residues

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.

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

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.
