Soft soldering fluxes - Test methods - Part 3: Determination of acid value, potentiometric and visual titration methods (ISO 9455-3:1992)

Specifies the two methods for a flux of types 1 and 2 only, as defined in ISO 9454-1. Gives precision of the two methods as determined by interlaboratory tests.

Flußmittel zum Weichlöten - Prüfverfahren - Teil 3: Bestimmung des Säurewertes, potentiometrische und visuelle Titrationsmethoden (ISO 9455-3:1992)

Dieser Teil von ISO 9455 legt zwei Methoden zur Bestimmung des Säurewertes eines Flussmittels der Typen 1 und 2 nach ISO 9454-1 fest. Methode A ist eine potentiometrische Titration und kann als Referenzmethode betrachtet werden. Methode B ist eine alternative Titrationsmethode über die visuelle Endpunktbestimmung.

Flux de brasage tendre - Méthodes d'essai - Partie 3: Détermination de l'indice d'acide par des méthodes de titrage potentiométrique et visuel (ISO 9455-3:1992)

La présente partie de l'ISO 9455 prescrit deux méthodes de détermination de l'indice d'acide des flux de type 1 ou 2 uniquement définis dans l'ISO 9454-1. La méthode A est une méthode de titrage potentiométrique. Elle est considérée comme la méthode de référence. La méthode B est une variante de méthode de titrage à repérage visuel de la fin de la réaction.

Foreword
IS0 (the International Organization for Standardization) is a worldwide
federation of national standards bodies (IS0 member bodies). The work
of preparing International Standards is normally carried out through IS0
technical committees. Each member body interested in a subject for
which a technical committee has been established has the right to be
represented on that committee. International organizations, govern-
mental and non-governmental, in liaison with ISO, also take part in the
work. IS0 collaborates closely with the International Electrotechnical
Commission (IEC) on all matters of electrotechnical standardization.
Draft International Standards adopted by the technical committees are
circulated to the member bodies for voting. Publication as an lnter-
national Standard requires approval by at least 75 9/o of the member
bodies casting a vote.
International Standard IS0 9455-3 was prepared by Technical Committee
ISO/TC 44, Welding and allied processes, Sub-Committee SC 12,
Soldering and brazing materials.
