Soft soldering fluxes - Test methods - Part 6: Determination and detection of halide (excluding fluoride) content (ISO 9455-6:2022)
This document specifies three quantitative methods for the determination of the ionic halide (excluding fluoride) content of soldering fluxes. Halides are calculated as chlorides. A useful qualitative test method for the detection of ionic halides is also described.
Method A is a potentiometric titration method for the determination of halide (excluding fluoride) content and is applicable to flux classes 1 and 2, defined in ISO 9454-1. This method, which is considered the reference method for these fluxes, is suitable for halide contents generally within the range of 0,05 % mass fraction to 2 % mass fraction in the non-volatile matter of the flux.
Method B is a titration method for the determination of the total halide (excluding fluoride) content of water-soluble fluxes. It is applicable to flux classes 2122 to 2124, 3112 to 3114 and 3212 to 3214, as defined in ISO 9454-1.
Method C is a titration method for the determination of the halide (excluding fluoride) content of water-soluble fluxes containing phosphates and is applicable to flux class 331, as defined in ISO 9454-1.
Method D is a qualitative test, using silver chromate test paper, for the presence of ionic halides. The technique can be used for all classes of flux.
Flussmittel zum Weichlöten - Prüfverfahren - Teil 6: Bestimmung und Nachweis des Halogenidgehaltes (außer Fluorid) (ISO 9455-6:2022)
Dieses Dokument legt drei quantitative Verfahren zur Bestimmung des Gehaltes ionischer Halogenide (außer Fluorid) eines Weichlötflussmittels fest. Die Halogenide werden als Chlorid berechnet. Ebenso wird ein brauchbares qualitatives Prüfverfahren zum Nachweis von ionischen Halogeniden beschrieben.
Verfahren A ist eine potentiometrische Titration zur Bestimmung des Halogenidgehaltes (außer Fluorid) und ist anwendbar auf Flussmittel der Klassen 1 und 2 nach ISO 9454 1. Dieses Verfahren dient als Referenzverfahren für diese Flussmittel und ist geeignet für Halogenidgehalte im Bereich von 0,05 % Massenanteil bis 2 % Massenanteil des nichtflüchtigen Bestandteiles des Flussmittels.
Verfahren B ist ein Titrationsverfahren zur Bestimmung des Gesamthalogenidgehaltes (außer Fluorid) wasserlöslicher Flussmittel, anwendbar für Flussmittel der Klassen 2122 bis 2124, 3112 bis 3114 und 3212 bis 3214 nach ISO 9454 1.
Verfahren C ist ein Titrationsverfahren zur Bestimmung des Halogenidgehaltes (außer Fluorid) wasserlöslicher Flussmittel, die Phosphate enthalten, und ist anwendbar für Flussmittel der Klasse 331 nach ISO 9454 1.
Verfahren D ist eine qualitative Prüfung, die mit Silberchromatpapier durchgeführt wird und die Anwesenheit von ionischen Halogeniden anzeigt. Dieses Verfahren kann für alle Flussmittelklassen angewandt werden.
Flux de brasage tendre - Méthodes d'essai - Partie 6: Dosage et détection des halogénures (à l'exception des fluorures) (ISO 9455-6:2022)
Le présent document spécifie trois méthodes quantitatives pour le dosage de la teneur en halogénure ionique (à l’exception du fluorure) dans les flux de brasage tendre. Les halogénures sont calculés comme des chlorures. Une méthode d’essai qualitative utile pour la détection des halogénures ioniques est également décrite.
La Méthode A est une méthode de titrage potentiométrique pour le dosage de la teneur en halogénure (à l’exception du fluorure) et s’applique aux classes de flux 1 et 2, définies dans l’ISO 9454-1. Cette méthode, qui est considérée comme la méthode de référence, convient pour les teneurs en halogénure généralement comprises entre 0,05 % fraction massique à 2 % fraction massique dans les matières non-volatiles du flux.
La Méthode B est une méthode de titrage pour le dosage de la teneur totale en halogénure (à l’exception du fluorure) dans les flux solubles dans l’eau. Elle s’applique aux classes de flux 2122 à 2124, 3112 à 3114 et 3212 à 3214, tel que défini dans l’ISO 9454-1.
La Méthode C est une méthode de titrage pour le dosage de la teneur en halogénure (à l’exception du fluorure) dans les flux solubles dans l’eau contenant des phosphates et s’applique classes de flux 331, tel que défini dans l’ISO 9454-1.
La Méthode D est un essai qualitatif qui utilise du papier réactif au chromate d’argent, pour détecter la présence d’halogénure ionique. Le technique peut être utilisée pour toutes les classes de flux.
Talila za mehko spajkanje - Preskusne metode - 6. del: Določevanje in detekcija halogenida (razen fluorida) (ISO 9455-6:2022)
Ta dokument določa tri kvantitativne metode za določevanje ionskega halida (razen fluorida) v talilih za mehko spajkanje. Halidi se izračunajo kot kloridi. Opisana je tudi uporabna kvalitativna preskusna metoda za določevanje ionskih halidov. Metoda A je potenciometrična titracijska metoda za določevanje halida (razen fluorida) ter se uporablja za razreda talil 1 in 2, kot je opredeljeno v standardu ISO 9454-1. Ta metoda se obravnava kot referenčna metoda za ta talila in je primerna za halide običajno v razponu 0,05 % do 2 % masnega deleža v nehlapni snovi talila. Metoda B je titracijska metoda za določevanje skupnega halida (razen fluorida) v vodi topnih topil. Uporablja se za razrede talil 2122 do 2124, 3112 do 3114 in 3212 do 3214, opredeljene v standardu ISO 9454-1. Metoda C je titracijska metoda za določevanje halida (razen fluorida) v vodi topnih topil, ki vsebujejo fosfate, in se uporablja za razred talil 331, kot je opredeljeno v standardu ISO 9454-1. Metoda D je kvalitativni preskus, pri katerem se prisotnost ionskih halidov določi s preskusnim papirjem s srebrovim kromatom. Tehniko je mogoče uporabiti za vse razrede talil.
