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 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 International Standard may be the subject of
patent rights. ISO shall not be held responsible for identifying any or all such patent rights.
International Standard ISO 2759 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 third edition cancels and replaces the second edition (ISO 2759:1983), which has been technically revised.
Annexes A, B, C and D form a normative part of this International Standard.

Introduction
This International Standard is applicable to boards with bursting strengths between 350 kPa (or 250 kPa for the
components of combined materials) and 5 500 kPa. All components of solid and corrugated fibreboard, irrespective
of bursting strength, should be tested by this International Standard.
For materials with bursting strengths less than 1 400 kPa, an alternative method, based on similar principles, is
specified in ISO 2758.
NOTE Due to differences in the specification of the apparatus, tests made on the same material using the procedures of
ISO 2758 and this International Standard will not necessarily give the same results.

INTERNATIONAL STANDARD ISO 2759:2001(E)
Board — Determination of bursting strength
1 Scope
This International Standard specifies a method for measuring the bursting strength of board submitted to increasing
hydraulic pressure. It is applicable to all types of board (including corrugated and solid fibreboard) having bursting
strengths within the range 350 kPa to 5 500 kPa. It is also applicable to papers or boards having bursting strengths
as low as 250 kPa if the paper or board is to be used to prepare a material of higher bursting strength, such as
corrugated board. In such cases, the measurements will not necessarily have the accuracy or precision stated for
this method and it is necessary to include a note in the test report stating that the test gave results that were below
the minimum value required by the method.
In the absence of any commercial agreement as to which method should be used for materials with bursting
strengths between 350 kPa and 1 400 kPa, all materials with bursting strengths below 600 kPa, except components
of solid and corrugated fibreboard, should be tested by ISO 2758 and the remainder by this International Standard.
2 Normative references
The following normative documents contain provisions which, through reference in this text, constitute provisions of
this International Standard. For dated references, subsequent amendments to, or revisions of, any of these
publications do not apply. However, parties to agreements based on this International Standard are encouraged to
investigate the possibility of applying the most recent editions of the normative documents indicated below. For
undated references, the latest edition of the normative document referred to applies. Members of ISO and IEC
maintain registers of currently valid International Standards.

3 Terms and definitions
For the purposes of this International Standard, the following terms and definitions apply.
3.1
bursting strength
maximum pressure developed by the hydraulic system in forcing an elastic diaphragm through a circular area of the
board when the pressure is applied in the manner described in the method
NOTE The indicated bursting pressure includes the pressure required to extend the diaphragm during the test.
3.2
burst index
bursting strength of the board divided by the grammage of the board determined in accordance with ISO 536

4Principle
A test piece, placed over a circular elastic diaphragm, is rigidly clamped at the periphery but free to bulge with the
diaphragm. Hydraulic fluid is pumped at a constant rate, bulging the diaphragm until the test piece ruptures. The
bursting strength of the test piece is the maximum value of the applied hydraulic pressure.
5 Apparatus
The apparatus shall contain, as a minimum, the features described in 5.1 to 5.4.
5.1 Clamping system, for clamping the test piece firmly and uniformly between two annular, plane, parallel
surfaces which shall be smooth (but not polished) and grooved as described in annex A, which also give
