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 1519 was prepared by Technical Committee ISO/TC 35, Paints and varnishes, Subcommittee SC 9,
General test methods for paints and varnishes.
This third edition cancels and replaces the second edition (ISO 1519:2002), which has been technically
revised. The main changes are:
a) A principle clause has been added.
b) The requirement to carry out the test at a controlled relative humidity has been deleted (although the
relative humidity is measured and recorded during the test). A maximum limit for the time between
conditioning and testing has therefore been added.
c) The supplementary test conditions (formerly Annex A) have been integrated in the test report.
d) Information has been given on the precision of the method.

Introduction
This International Standard is one of six 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 five documents are:
⎯ ISO 1520, Paints and varnishes — Cupping test
⎯ ISO 6272-1, Paints and varnishes — Rapid-deformation (impact resistance) tests — Part 1: Falling-
weight test, large-area indenter
⎯ ISO 6272-2, Paints and varnishes — Rapid-deformation (impact resistance) tests — Part 2: Falling-
weight test, small-area indenter
⎯ ISO 6860, Paints and varnishes — Bend test (conical mandrel)
⎯ ISO 17132, Paints and varnishes — T-bend test
The method chosen will depend on the property to be measured and on agreement between the interested
parties. In principle, all these tests differ from each other technically and in their accuracy.

INTERNATIONAL STANDARD ISO 1519:2011(E)

Paints and varnishes — Bend test (cylindrical mandrel)
1 Scope
This International Standard specifies an empirical test procedure for assessing the resistance of a coating of
paint, varnish or related product to cracking and/or detachment from a metal or plastics substrate when
subjected to bending round a cylindrical mandrel under standard conditions.
For a multi-coat system, each coat can be tested separately or the complete system can be tested.
The method specified can be carried out
⎯ either as a “pass/fail” test, by carrying out the test with a single specified size of mandrel, to assess
compliance with a particular requirement;
⎯ or by repeating the procedure using successively smaller mandrels to determine the diameter of the first
mandrel over which the coating cracks and/or becomes detached from the substrate.
Two types of apparatus are specified, type 1 being appropriate for use on test panels of thickness up to
0,3 mm, and type 2 for use on test panels of thickness up to 1,0 mm. Both types of apparatus have been
found to give similar results with the same coating, but normally only one will be used for testing a given
product.
