Metallic and other inorganic coatings - Measurement of mass per unit area - Review of gravimetric and chemical analysis methods (ISO 10111:2019)

This document gives guidelines 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 chemical or physical vapour deposition 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;
— gravimetric procedures for weighing the uncoated substrate and the coated (finished) specimen to
determine the coating surface density;
— analytical procedures that utilize dissolution of the coating for determination of the coating surface
density by instrumental chemical analysis methods.
With the exception of the gravimetric method as described in ISO 3892, this document does not give the
measurement uncertainties of the methods cited.

Revêtements métalliques et autres revêtements inorganiques - Mesurage de la masse surfacique - Présentation des méthodes d'analyse gravimétrique et chimique (ISO 10111:2019)

Le présent document donne des recommandations relatives aux 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, déposition en phase gazeuse par procédé chimique ou physique, anodisation ou conversion chimique.
Il 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 gravimétriques pour la pesée du métal de base nu et de l'éprouvette revêtue (finie) 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 de la masse surfacique du dépôt par des méthodes instrumentales d'analyse chimique.
Sauf pour la méthode gravimétrique telle que décrite dans l'ISO 3892, le présent document 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.

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.

For an explanation of the voluntary nature of standards, the meaning of ISO specific terms and

expressions related to conformity assessment, as well as information about ISO's adherence to the

World Trade Organization (WTO) principles in the Technical Barriers to Trade (TBT) see www .iso

.org/iso/foreword .html.

This document was prepared by Technical Committee ISO/TC 107, Metallic and other inorganic coatings.

This second edition cancels and replaces the first edition (ISO 10111:2000), which has been technically

revised. The following changes have been made:

a) a gravimetric method has been added for weighing the uncoated substrate and the finished sample;

b) the surface area increase caused by surface roughness has been considered to obtain a more

realistic estimation of local geometric coating thickness (optional);

c) Annex A, which gives reagents for etching or stripping solutions, has been changed to informative

as other solutions can be applied;

d) reagents in Annex A that referred to no longer existing standards or which contain hazardous

chemicals have been removed;
e) outdated and uncited references in the Bibliography have been removed.

Any feedback or questions on this document should be directed to the user’s national standards body. A

1 Scope

This document gives guidelines 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 chemical or physical vapour deposition using

gravimetric and other chemical analysis procedures that have attained some degree of national or

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;

— gravimetric procedures for weighing the uncoated substrate and the coated (finished) specimen to

determine the coating surface density;

density by instrumental chemical analysis methods.

With the exception of the gravimetric method as described in ISO 3892, this document does not give the

measurement uncertainties of the methods cited.

4 Principle
The mass of a coating over a measured area is determined by

a) weighing the test specimen before and after dissolving the coating in a reagent or electrolyte that

does not attack the substrate, or

b) weighing the coating after dissolving the substrate in a reagent that does not attack the coating, or

c) dissolving both the coating and the substrate, or the coating alone, and quantitatively analysing the

resulting solution, or

d) weighing the test specimen before and after the coating process, provided that the mass of the

substrate material removed during those pre-treatment steps, after which a weighing would

negatively affect the coating deposition steps, is negligible compared to the mass of the coating.

The surface density of the coating is calculated from the mass and area measurements. Its thickness is

based on the mass, area and density of the coating material.
5 Special equipment

Certain specialized chemical, electrochemical and chemical analysis equipment is required for some of

the specific methods referred to in Table A.1 (see Clauses 8 and 9).
6 Preparation of test specimen
6.1 Size

The specimen should be large enough to permit area and mass measurement of adequate accuracy (see

Clauses 8 and 9).
6.2 Shape

The shape of the test specimen should be such that the surface area can be readily measured without

difficulty. A rectangular or circular test specimen is usually suitable.
6.3 Edge condition

If the area to be measured is small and has to be known accurately, the edges may need to be dressed

to remove smeared coating, to remove loose burrs and to provide well-defined and (for rectangles)

straight edges. This should be considered for areas less than 100 mm .

One method of dressing the edges of a rectangular specimen involves clamping the specimen between

two plastic or metal blocks with the edge of the specimen flush with the edges of the blocks and then

grinding and polishing the edges metallographically.
6.4 Heat treatment

If the substrate has to be dissolved in such a way as to leave the coating intact, it may be desirable to

first treat the test specimen so that the coating will not curl up tightly or fall apart. Some gold deposits

of 1,5 mg/cm (< 0,9 μm) will
