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 3037 was prepared by Technical Committee ISO/TC 6, Paper, board and pulps, Subcommittee SC 2,
Test methods and quality specifications for paper and board.
This fourth edition cancels and replaces the third edition (ISO 3037:1994), which has been technically revised.
Specifications for the compression testing machine have been replaced by reference to ISO 13820. Details of
acceptable cutting devices have been moved to an informative annex and have been replaced by specification
of the quality of cut.

ISO 3037:2007(E)
Introduction
A variety of methods for the determination of edgewise crush resistance are in use in different parts of the
world. These can be classified into three groups as follows:
a) Those in which a carefully cut rectangular test piece is tested without any special treatment or
modification (e.g. ISO 3037).
b) Those in which the edges of the test piece to which the force is applied are waxed, to prevent the test
result being influenced by “edge effects“ (e.g. ISO 13821, Corrugated fibreboard — Determination of
edgewise crush resistance — Waxed edge method).
c) Those in which the test piece edges are not waxed but the shape of the test piece is such that the length
is substantially reduced at a point midway between the loaded edges, in order to induce the failure to
occur away from those edges.
The dimensions of the test piece vary from one group to the other and, in group c), the methods vary in the
shape and method of reducing the length, and in whether or not the test piece is held in a clamp during
crushing.
The methods may not give the same numerical results, but it can be shown that most of them can be used to
predict the top-to-bottom compression strength which will be achieved when the board is properly converted
into a transport package.
This International Standard describes a method from group a). It is intended as a method for quality
measurement and quality specification purposes and is selected because it correlates with the top-to-bottom
compression strength of the final transport package and because it is the simplest and most operationally
convenient method, an important factor when large numbers of tests need to be conducted. However, it does
not measure the actual intrinsic compressive strength of the corrugated fibreboard, giving lower results than
most of the methods in groups b) and c). This systematic difference is due to edge effects.
Other methods may be used for other purposes, particularly when the object of the test is to study
fundamental structural characteristics of the package.
There are methods available for calculating the edgewise crush resistance from the compression strength of
the component papers.
INTERNATIONAL STANDARD ISO 3037:2007(E)

Corrugated fibreboard — Determination of edgewise crush
resistance (unwaxed edge method)
1 Scope
This International Standard specifies an unwaxed edge method for the determination of the edgewise crush
resistance of corrugated fibreboard. It is applicable to all corrugated fibreboard grades.
2 Normative references
The following referenced documents are indispensable for the application of this document. For dated
references, only the edition cited applies. For undated references, the latest edition of the referenced
document (including any amendments) applies.
ISO 186, Paper and board — Sampling to determine average quality
ISO 187, Paper and board — Standard atmosphere for conditioning and testing and procedure for monitoring
the atmosphere and conditioning of samples
ISO 13820, Paper, board and corrugated fibreboard — Description and calibration of compression-testing
equipment
3 Terms and definitions
For the purposes of this document, the following terms and definitions apply.
3.1
edgewise crush resistance
maximum force per unit length that a test piece of corrugated fibreboard can support until the onset of failure
when a compressive force is applied parallel to the flutes
4 Principle
A rectangular test piece of corrugated fibreboard, placed between the platens of a compression tester with the
flutes perpendicular to the surfaces of the platens, is subjected to an increasing compressive force until failure
occurs. The maximum force sustained by the test piece is measured.
5 Apparatus
5.1 Fixed-platen compression testing machine as described in ISO 13820. It is preferable to avoid the
use of emery paper on the platens.
While it is safer to avoid the use of emery paper on the platens, because it is a requirement of other test
methods, the platens may be faced with very fine emery paper of a grade not coarser than 00. Where this is
done, due regard should be paid to maintaining the flatness and parallelism requirements specified for the
faces.
ISO 3037:2007(E)
5.2 Cutting device, such as a high-speed table saw or Billerud-type cutter (see Annex A), capable of
cutting test pieces to the quality of cut described in 8.3 and 8.4.
5.3 Guide blocks, two rectangular, smooth-finished, blocks of dimensions approximately
20 mm x 20 mm x 100 mm, to support the test pie
