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 17132 was prepared by Technical Committee ISO/TC 35, Paints and varnishes, Subcommittee SC 9,
General test methods for paints and varnishes.

Introduction
This International Standard is one of five standards which specify empirical test procedures for assessing the
resistance of coatings of paints, varnishes and related products to cracking and/or detachment from the
substrate under different conditions of deformation. The other International Standards are ISO 1519,
ISO 1520, ISO 6272 and ISO 6860.
The T-bend test has already been standardized in the USA (ASTM D 4145), Europe (EN 13523-7) and Japan
(JIS G 3312). The test methods in these standards are basically the same, but differ from each other in details
such as
⎯ whether the coated test panel is folded back on itself or is bent round a mandrel or a test panel used as a
spacer;
⎯ the way in which the test result is expressed.
In this International Standard, the basic contents common to the US, European and Japanese standards have
been adopted, but details in which the US, European and Japanese standards differ, in particular the use of a
mandrel or spacer panels, have been made subject to agreement between the interested parties.

INTERNATIONAL STANDARD ISO 17132:2007(E)

Paints and varnishes — T-bend test
1 Scope
This International Standard describes a method of evaluating the flexibility and adhesion of an organic coating
on a metallic substrate by observing the cracking or loss of adhesion when a coated test panel is bent.
The method can be used to confirm whether paints, varnishes or related products meet a given test
requirement in a pass/fail test, or to determine the minimum bending diameter at which cracking does not
occur.
