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 7263 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 7263:1994), which has been technically
revised. The major revision is the change in how the time between fluting and compression testing is
expressed. Description and calibration of the compression testing equipment have been eliminated and the
appropriate International Standard is referenced. Precision statements for the rigid platen instrument and for
the procedure involving conditioning prior to testing have been added. An annex describing steps to be taken
for fluter maintenance is included.

Introduction
The flat crush resistance of laboratory-fluted corrugating medium is regarded as an important property
because it is an indication of the potential flat crush resistance of corrugated fibreboard made from that
medium. The corrugated medium is fluted by passing it between heated rollers. Two different test procedures
are then widely used:
a) the fluted corrugating medium is compressed immediately after fluting (i.e. 5 s to 8 s after fluting);
b) the fluted corrugating medium is conditioned for 30 min to 35 min under standard laboratory test
conditions before being compressed.
Procedure a) generally gives considerably higher results than those obtained with procedure b). The
differences in results are claimed to be caused by
⎯ the lower moisture content (and thus higher stiffness) of the unconditioned fluted corrugating medium,
⎯ the change in flute profile which occurs during the conditioning period.
Since considerable advantages are claimed for both procedures and both are widely used, this International
Standard describes both procedures.
A method of determining the flat crush resistance of manufactured corrugated fibreboard is given in
ISO 3035:1982, Single-faced and single-wall corrugated fibreboard — Determination of flat crush resistance.
