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 2.

The main task of technical committees is to prepare International Standards. 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 document may be the subject of patent

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

ISO 17186 was prepared by the European Committee for Standardization (CEN) Technical Committee

CEN/TC 289, Leather, in collaboration with the Physical Test Commission of the International Union of

Leather Technologists and Chemists Societies (IUP Commission, IULTCS), in accordance with the Agreement

on technical cooperation between ISO and CEN (Vienna Agreement).

IULTCS, originally formed in 1897, is a world-wide organization of professional leather societies to further the

advancement of leather science and technology. IULTCS has three Commissions, which are responsible for

establishing international methods for the sampling and testing of leather. ISO recognizes IULTCS as an

international standardizing body for the preparation of test methods for leather.

This second edition cancels and replaces the first edition (ISO 17186:2002), which has been technically

revised, particularly in Clause 6 with the addition of alternative methods of measurement and analysis.

Leather — Physical and mechanical tests — Determination of
surface coating thickness
1 Scope

This International Standard specifies a method for determining the thickness of the surface coating applied to

leather when measured under zero compression. It is applicable to all types of leather.

2 Normative references

The following referenced documents are indispensable for the application of this document. For dated

references, only the edition cited applies. For undated references, the latest edition of the referenced

document (including any amendments) applies.

ISO 2418, Leather — Chemical, physical and mechanical and fastness tests — Sampling location

ISO 2419, Leather — Physical and mechanical tests — Sample preparation and conditioning

3 Principle

A section of leather is taken perpendicular to the coated surface. The thickness of the surface coating is

measured using a microscope and expressed both as a thickness and as a percentage of the total thickness.

4 Apparatus

4.1 Light microscope or scanning electron microscope, which can be operated with an object-field size

of 1 mm  1 mm, or lower, and is

 fitted with a camera-image unit connected to a computer (resolution of at least 500  500 pixels), or

 fitted with a photographical unit, or
 equipped with an eyepiece with a graduated scale (at least 100 scale marks).

NOTE 100 scale marks correspond to a scaling of 10 µm in the object-field dimension for an object-field size of

1 mm  1 mm.

For measurement of coating thicknesses of less than 50 µm, an object-field size of 0,4 mm  0,4 mm or lower

has to be used. For measurement of values of less than 15 µm, a scanning electron microscope with a

suitable object-field dimension should be used.
4.2 Razor blade.

4.3 Grid or similar calibration device, reading to at least 10 µm and suitable for use in the light

microscope or scanning electron microscope.

4.4 Coating unit, using sputter or evaporation, including a suitable element or alloy (e.g. gold) for coating,

if a scanning electron microscope is used.
4.5 Specimen stubs, suitable for a scanning electron microscope.

5 Sampling and sample preparation
5.1 Sample in accordance with ISO 2418. Condition in accordance with ISO 2419.

5.2 Cut three test pieces of approximately 10 mm  10 mm. If there is a requirement for more than two

hides or skins to be tested in one batch, then only one test piece need be taken from each hide or skin,

provided that the overall total is not less than three pieces. Section each of the three test pieces as described

in 5.3.

5.3 Place the cutting edge of the razor blade (4.2) on the flesh side, with the blade perpendicular to the

leather surface, and press the blade through the whole thickness of the leather, ensuring that the blade

remains vertical. It is recommended that a new razor blade be used for each section.

If using a scanning electron microscope, stick a section prepared as described above onto a specimen stub

(4.5) with the cut surface uppermost. Coat the stub and section in the coating unit (4.4) so that a sufficient

image quality can be obtained.
