Metallische und andere anorganische Überzüge - Messung der flächenbezogenen Masse - Übersicht über gravimetrische und chemische Analyseverfahren (ISO 10111:2000)
1.1 Allgemeines
Diese Internationale Norm erfasst allgemeine Verfahren zur Bestimmung der mittleren flächenbezogenen Masse von anodischen Oxidüberzügen, autokatalytisch, mechanisch, durch chemische Umwandlung, durch elektrolytische Abscheidung, durch Schmelztauchverfahren und durch Vakuum abgeschiedenen Überzügen durch gravimetrische und andere chemische Analysenverfahren die eine gewisse Bedeutung in der Nationalen und Internationalen Normung erreicht haben.
Eine Vielzahl von Verfahren werden beschrieben und sind eingeschlossen:
- Gravimetrische Verfahren für die chemische oder elektrochemische Auflösung des Überzugs oder des Substrats zur Bestimmung der flächenbezogenen Masse;
- Analytische Verfahren die die Auflösung des Überzugs für eine photometrische oder volumetrische Bestimmung der flächenbezogenen Masse nutzen;
- Zerstörungsfreie physikalische Instrumentenanalyse des Überzugs zur Bestimmung der flächenbezogenen Masse.
Außer für das gravimetrische Verfahren (ISO 3892:1980) werden in dieser Internationalen Norm keine Messunsicherheiten angegeben.
1.2 Quellen
Die im Anhang A zitierten Entmetallisierungsverfahren werden in der allgemein zugänglichen Fachliteratur beschrieben, oder sie sind zumindest von einem Laboratorium regelmäßig angewendet worden.
1.3 Einschränkungen
Die beschriebene Verfahren können für viele Kombinationen Überzug - Substrat angewandt werden. Sie sind nicht anwendbar, wenn weder der Überzug noch das Substrat chemisch oder physikalisch vollständig voneinander getrennt werden können, und ein Bestandteil, der beiden gemeinsam ist, kann nicht ohne weiteres abgetrennt werden kann (z.B. Nickel-Phosphor-Legierung von Nickel).
Revêtements métalliques et autres revêtements inorganiques - Mesurage de la masse surfacique - Présentation des méthodes d'analyse gravimétrique et chimique (ISO 10111:2000)
La présente Norme internationale présente un aperçu des méthodes générales d'analyse gravimétrique ou chimique de diverses sortes ayant atteint un degré de normalisation à l'échelon national ou international, utilisées pour la détermination de la masse surfacique moyenne de revêtements obtenus par dépôt électrolytique, dépôt par immersion, dépôt autocatalytique, matoplastie, dépôt sous vide, anodisation ou conversion chimique. Elle décrit un certain nombre de ces procédés de détermination de la masse surfacique, parmi lesquels : - des méthodes gravimétriques pour la mise en solution chimique ou électrochimique du dépôt ou du métal de base permettant la détermination de la masse surfacique du dépôt ; - des méthodes analytiques qui utilisent la mise en solution du dépôt en vue d'une détermination photométrique ou gravimétrique de la masse surfacique du dépôt ; - une méthode volumétrique ou une analyse physique du dépôt par des moyens non destructifs afin de déterminer sa masse surfacique. Sauf pour la méthode gravimétrique décrite dans l'ISO 3892:-, la présente Norme internationale n'indique pas les incertitudes de mesurage liées aux méthodes citées.

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 10111 was prepared by Technical Committee ISO/TC 107, Metallic and other inorganic
coatings, Subcommittee SC 2, Test methods.
Annex A forms a normative part of this International Standard.

INTERNATIONAL STANDARD ISO 10111:2000(E)
Metallic and other inorganic coatings — Measurement of mass per
unit area — Review of gravimetric and chemical analysis methods
WARNING — The methods referred to in this International Standard can involve hazardous materials,
operations and equipment. This International Standard does not purport to address all of the safety
problems associated with its use. It is the responsibility of whoever uses this International Standard to
consult and establish appropriate safety and health practices and determine the applicability of regulatory
limitations prior to its use.
1 Scope
1.1 General
This International Standard outlines general methods for determining the average surface density over a measured
area of anodic oxide or of a coating deposited autocatalytically, mechanically, by chemical conversion, by
electrodeposition, by hot dip galvanizing and by vacuum using gravimetric and other chemical analysis procedures
that have attained some degree of national or international standardization.
A variety of procedures are described and include:
� gravimetric procedures for chemical or electrochemical dissolution of the coating or the substrate to determine
the coating surface density;
� analytical procedures that utilize dissolution of the coating for photometric or volumetric determination of the
coating surface density;
� non-destructive instrumental physical analysis of the coating to determine the surface density.
With the exception of the gravimetric method described in ISO 3892:—, this International Standard does not give
the measurement uncertainties of the methods cited.
1.2 Sources
The stripping methods cited in annex A are described in specifications in the open literature or have been used
routinely by at least one laboratory.
1.3 Restrictions
The procedures described can be used for many coating-substrate combinations. They cannot be used where
neither the coating nor substrate material can be completely removed, one from the other by chemical or physical
means and there is a constituent common to both that is not readily separated (e.g. nickel phosphorus alloy on
nickel).
NOTE The measurement of very thin coatings on very small pieces can result in a reduction in accuracy and a lack of
repeatability. Several measurements using a combination of different procedures on similar samples might overcome this
situation.
ISO 10111:2000(E)
1.4 Limitations
In principle, the gravimetric procedures can be used to measure very thin coatings or to measure coatings over
small areas, but not thin coatings over small areas. The limits depend on the required accuracy; e.g., 2,5 mg/cm of
2 2 2
coating might require 1 cm , but 0,1 mg/cm of coating would require 25 cm to obtain 2,5 mg of coating. These
limitations do not apply to the chemical analysis methods.
The gravimetric method does not indicate the presence of bare spots or sites with thicknesses lower than the
specified minimum in the measuring areas. In addition, the single value obtained from each measuring area is the
mean thickness of that area. There can be no further mathematical analysis of this single value, for example, for
statistical process control purposes.
