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 20566 was prepared by Technical Committee ISO/TC 35, Paints and varnishes, Subcommittee SC 9, General
test methods for paints and varnishes.
This second edition cancels and replaces the first edition (ISO 20566:2005), which has been technically revised.
The main technical changes are:
a) a 'terms and definitions' clause has been added, defining the terms mar, scratch, scratch resistance, double
pass, test area and reflow effect;
b) tolerances have been added to any figures;
c) the spread of jet has been changed from 60° to 65°;
d) a specification of the thickness of test panels has been added;
e) the procedure has been stated more precisely;
f) visual examination of the test panels has been added;

Introduction
With this testing procedure, it is important to note that the test results will not, over time, remain constant as a result
of changes to the brush material, as the brushes age the test will become more severe. Additionally, a relation of
the position of the test sample on the test panel holder was observed. As a result, the test procedure is suitable
only for comparative tests at any one time for relatively short runs. The absolute readings attained for different
numbers of operating hours are not
