(Main)Metallic coatings - Determination of porosity in gold coatings on metal substrates - Nitric acid vapour test (ISO 14647:2000)
Metallic coatings - Determination of porosity in gold coatings on metal substrates - Nitric acid vapour test (ISO 14647:2000)
This International Standard specifies equipment and a method for using nitric acid vapour to determine porosity in
gold coatings, particularly electrodeposits and clad metals used on electrical contacts.
This method is designed to show whether the porosity level is less than or greater than some value that, by
experience, is considered by the user to be acceptable for the intended application.
It is suitable for inlays or claddings containing 75 % or more of gold, for electrodeposits containing 95 % or more of
gold or for substrates of copper, nickel and their alloys that are commonly used in electrical contacts.
The nitric acid vapour test is too severe to be used for gold coatings less than 0,6 _m thick. It is also not suitable for
coatings that are less noble than gold or platinum, such as palladium and its alloys, or gold-flashed palladium and
its alloys.
Several other porosity testing methods are described in ISO 10308 and in the literature (see e.g. Bibliography, [1]
and [2]).
Metallische Überzüge - Bestimmung der Porosität in Goldbeschichtungen auf Metallsubstraten - Salpetersäure-Dampftest (ISO 14647:2000)
Diese Internationale Norm legt die Prüfeinrichtung und ein Verfahren zur Bestimmung der Porosität mittels Salpetersäuredampf in Goldüberzügen, insbesondere galvanische Abscheidungen und Plattierungen, für elektrische Kontakte fest.
Dieses Verfahren beabsichtigt aufzuzeigen, ob die Porosität geringer oder größer als ein Wert ist, der vom Anwender als erfahrungsgemäß zulässig für den vorgesehenen Verwendungszweck gilt.
Sie ist geeignet für Inlays oder Plattierungen, die mindestens 75 % Gold enthalten, für galvanische Überzüge, die mehr als 95 % Gold enthalten, oder für Grundwerkstoffe aus Kupfer, Nickel und deren Legierungen, die gewöhnlich für elektrische Kontakte verwendet werden.
Die Prüfung mit Salpetersäuredampf ist für Goldüberzüge mit einer geringeren Dicke als 0,6 µm zu streng. Außerdem ist diese Prüfung ungeeignet für metallische Überzüge, die weniger edel als Gold oder Platin sind, z. B. Palladium und dessen Legierungen oder teilvergoldetes Palladium und dessen Legierungen.
In ISO 10308 und in der Literatur (siehe z. B. Literaturhinweise [1] und [2]) sind mehrere andere Porositätsprüfverfahren beschrieben.
Revêtements métalliques - Détermination de la porosité des revêtements d'or sur les substrats de métal - Essai à la vapeur d'acide nitrique (ISO 14647:2000)
La présente Norme internationale spécifie les matériels et une méthode d'utilisation de la vapeur d'acide nitrique
pour déterminer la porosité des revêtements d'or, plus particulièrement les dépôts électrolytiques et les métaux
plaqués utilisés sur les contacts électriques.
Cette méthode d'essai est conçue pour déterminer si le niveau de porosité est inférieur ou supérieur à une certaine
valeur qui, par expérience, est considérée comme acceptable par l'utilisateur pour l'application concernée.
Elle convient aux incrustations ou aux placages contenant 75 % ou plus d'or ou aux dépôts électrolytiques
contenant 95 % ou plus d'or sur les substrats de cuivre ou de nickel, ainsi que leurs alliages couramment utilisés
pour les contacts électriques.
L'essai à la vapeur d'acide nitrique est trop rigoureux pour être utilisé avec les revêtements d'or dont l'épaisseur est
inférieure à 0,6 μm. Il ne convient également pas aux revêtements moins nobles que l'or ou le platine, tels que le
palladium et ses alliages, ou le palladium à couche mince d'or et ses alliages.
D'autres méthodes différentes d'essai de porosité sont décrites dans l'ISO 10308 et dans la documentation
technique (voir par exemple [1] et [2] dans la bibliographie).
Kovinske prevleke - Ugotavljanje poroznosti v zlatih prevlekah na kovinskih podlagah - Preskus s hlapi dušikove kisline (ISO 14647:2000)
Ta mednarodni standard določa opremo in metodo za uporabo hlapov dušikove kisline pri ugotavljanju poroznosti v zlatih prevlekah, zlasti v galvanskih prevlekah in ploščah, prevlečenih s kovino, ki se uporabljajo za električne kontakte. Ta metoda je zasnovana tako, da pokaže, ali je raven poroznosti manjša ali večja od določene vrednosti, ki na podlagi uporabnikovih izkušenj velja kot sprejemljiva za predvideno uporabo. Primerna je za vložke ali obloge z vsebnostjo 75 % ali več zlata, galvanske prevleke z vsebnostjo 95 % ali več zlata ali podlage iz bakra, niklja in njunih zlitin, ki se pogosto uporabljajo za električne kontakte. Preizkus s hlapi dušikove kisline na zlatih prevlekah z debelino, manjšo od 0,6 μm, je prezahteven. Prav tako ni primeren za prevleke, ki so manj plemenite kot zlato ali platina, npr. paladij in njegove zlitine ali z zlatom prevlečen paladij in njegove zlitine. V standardu ISO 10308 in literaturi (glej bibliografijo [1] in [2]) je opisanih več drugih metod preskušanja poroznosti.
