Soft soldering fluxes - Test methods - Part 9: Determination of ammonia content (ISO 9455-9:2020)
The principle of the method specified is to distil a prepared flux solution with sodium hydroxide to expel the ammonia present in the flux, to pass the resulting distillate into a standard sulfuric acid solution, to titrate the excess acid with sodium hydroxide solution and to calculate the ammonia content of the flux. Applies to fluxes of class 3.1.1 only, as defined in ISO 9454-1.
Flussmittel zum Weichlöten - Prüfverfahren - Teil 9: Bestimmung des Ammoniumgehaltes (ISO 9455 9:2020)
Dieses Dokument legt ein Destillationsverfahren zur Bestimmung des Ammoniumgehaltes von festen, pastösen oder flüssigen Flussmitteln fest. Das Verfahren ist nur für die Flussmittel der Klassen 311 und 321 nach ISO 9454 1 anwendbar.
Flux de brasage tendre - Méthodes d'essai - Partie 9: Dosage de l'ammoniac (ISO 9455-9:2020)
La présente partie de l'ISO 9455 prescrit une méthode de distillation permettant de doser l'ammoniac contenu dans les flux solides ou liquides. La méthode est applicable uniquement aux flux de classe 3.1.1 définis dans l'ISO 9454-1.

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out
through ISO 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, governmental and non-governmental, in liaison with ISO, also take part in the work.
ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of
electrotechnical standardization.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www .iso .org/ directives).
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of
any patent rights identified during the development of the document will be in the Introduction and/or
on the ISO list of patent declarations received (see www .iso .org/ patents).
Any trade name used in this document is information given for the convenience of users and does not
constitute an endorsement.
