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 com-
mittees. 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 liai-
son 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 part of ISO 4623 may be the subject of patent
rights. ISO shall not be held responsible for identifying any or all such patent rights.
International Standard ISO 4623-1 was prepared by Technical Committee ISO/TC 35, Paints and varnishes, Sub-
committee SC 9, General test methods for paints and varnishes.
This first edition of ISO 4623-1 cancels and replaces ISO 4623:1984, of which it constitutes a minor technical revi-
sion.
ISO 4623 consists of the following parts, under the general title Paints and varnishes — Determination of resistance
to filiform corrosion:
— Part 1: Steel substrates
— Part 2: Aluminium substrates
Annex A forms a normative part of this part of ISO 4623. Annex B is for information only.

ISO 4623-1:2000(E)
Introduction
A scribed mark cut through a coating of paints or varnishes on steel can give rise to filiform corrosion. This corrosion
tends to develop when the relative humidity is high and when traces of salts are present either under the paint coating
or at breaks in the coating. A certain amount of under-rusting of the substrate, starting from the scribed mark, will al-
ways occur. Filiform corrosion, however, is considered to be present only if the typical pattern in the form of threads
is obvious.

Part 1:
Steel substrates
1 Scope
This part of ISO 4623 is one of a series of standards dealing with the sampling and testing of paints, varnishes and
related products.
It describes a test procedure for assessing the protective action of coatings of paints or varnishes on steel against
filiform corrosion arising from a scribed mark cut through the coating.
