Konversionsschichten auf metallischen Werkstoffen - Bestimmung der flächenbezogenen Masse der Schichten Gravimetrische Verfahren (ISO 3892:2000)

Anwendungsbereich
In dieser Internationalen Norm werden gravimetrische Verfahren zur Bestimmung der flächenbezogenen Masse von Konversionsschichten auf metallischen Werkstoffen festgelegt.
Die Verfahren sind anwendbar auf:
3 Phosphatschichten auf Eisen und Stahl;
3 Phosphatschichten auf Zink und Cadmium;
3 Phosphatschichten auf Aluminium und seinen Legierungen;
3 Chromatschichten auf Zink und Cadmium;
3 Chromatschichten auf Aluminium und seinen Legierungen.
Die Verfahren sind nur auf Konversionsschichten anwendbar, die keinerlei zusätzliche Schichten wie Öl, auf Wasser oder auf Lösemittel basierende Polymere oder Wachs aufweisen.
Die Verfahren zeigen nicht die Anwesenheit unbeschichteter Stellen oder Flecken mit Dicken unterhalb der auf den Messflächen festgelegten Mindestdicke an. Außerdem entspricht der an jeder Messfläche ermittelte Einzelwert einer mittleren Dicke dieser Fläche. Daher ist keine weitere mathematische Untersuchung dieses Einzelwertes möglich, z. B. für die statistische Prozesskontrolle.

Couches de conversion sur matériaux métalliques - Détermination de la masse par unité de surface - Méthodes gravimétriques (ISO 3892:2000)

La présente Norme internationale spécifie des méthodes gravimétriques pour la détermination de la masse par unité de surface des couches de conversion de matériaux métalliques.  Les méthodes sont applicables aux  - couches de phosphate formées sur du fer et de l'acier;  - couches de phosphate formées sur du zinc et du cadmium;  - couches de phosphate formées sur de l'aluminium et ses alliages;  - couches de chromate formées sur du zinc et du cadmium;  - couches de chromate formées sur de l'aluminium et ses alliages.  Ces méthodes ne sont applicables qu'aux couches de conversion dénuées de tout revêtement complémentaire, tel que huile, polymères à base de solvants ou d'eau, ou cire.  Ces méthodes n'indiquent pas la présence de points ou d'emplacements non revêtus dont les épaisseurs sont inférieures au minimum spécifié dans les aires de mesurage. De plus, les valeurs individuelles obtenues de chaque aire de mesurage correspondent aux épaisseurs moyennes sur cette aire. Il ne peut y avoir d'autre analyse mathématique de cette valeur individuelle, à des fins de contrôle statistique, par exemple.

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.

International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 3.

Draft International Standards adopted by the technical committees are circulated to the member bodies for voting.

Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote.

Attention is drawn to the possibility that some of the elements of this International Standard may be the subject of

patent rights. ISO shall not be held responsible for identifying any or all such patent rights.

International Standard ISO 3892 was prepared by Technical Committee ISO/TC 107, Metallic and other inorganic

coatings, Subcommittee SC 2, Methods of inspection and coordination of test methods.

This second edition cancels and replaces the first edition (ISO 3892:1980), which has been technically revised.
