Paints and varnishes - Guidelines for the introduction of scribe marks through coatings on metallic panels for corrosion testing (ISO 17872:2007)
This International Standard describes methods of scribing coated steel or test-pieces for corrosion tests, where the coating system is applied at dry film thicknesses of less than 500 µm . It is intended as a guideline only, being based on the results of a collaborative trial with no subsequent corrosion testing having been carried out to determine the suitability of the introduced scribe marks for such tests. This International Standard covers the scribing of metallic panels or test pieces made from steel, chemically treated steel, aluminium or aluminium alloy, and chemically treated aluminium.

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 17872:2007(E)
Introduction
Many International Standards deal with corrosion testing, where scribe marks are introduced through a
coating to a metallic substrate. However, the method of scribe-mark introduction (scribing pattern, tools, etc.)
is not standardized across these standards.
The main purposes of an intentionally inflicted damage in a coating prior to corrosion testing are as follows:
a) to simulate and to investigate how a specific type of damage behaves during exposure;
b) to obtain an accelerated response during a corrosion test, e.g. at quality control during production;
c) to investigate the general durability of a coating by observation of the rate of corrosion spread after
exposure.
Preliminary investigations have shown that several variants, both in terms of shape and dimensions, of
scribing tools are used. This variation occurs both across countries and within countries. The effect of using
different tools is the production of scribe marks with different cross-sectional shape, depth and exposed metal
area. These differences will greatly affect test results obtained during corrosion tests, as the intention of
introducing scribe marks into a coating system is such that oxygen and the electrolyte present during
exposure testing can obtain access to a well-defined and active metal surface.
The actual method used to introduce a scribe mark depends on the coating type and thickness. However, in
all cases it is preferable if the cross-section is as smooth as possible, the metallic substrate is exposed evenly
and no coating remains on the exposed substrate. Additionally, it is desirable that scribing methods are
consistent across related International Standards.
The scribing method greatly affects how the corrosion process occurs and the reproducibility when tests are
repeated under the same conditions. In order to obtain anticorrosive results with high accuracy and
reproducibility, accurate and consistent scribing is required.
