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.

The procedures used to develop this document and those intended for its further maintenance are

described in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the

different types of ISO documents should be noted. This document was drafted in accordance with the

editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).

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. Details of

any patent rights identified during the development of the document will be in the Introduction and/or

on the ISO list of patent declarations received (see www.iso.org/patents).

This sixth edition cancels and replaces the fifth edition (ISO 3037:2013), which has been technically

revised.
The main changes compared to the previous edition are as follows:

— the title has changed from "Corrugated fibreboard - Determination of edgewise crush resistance

(unwaxed edge method)" to "Corrugated fibreboard - Determination of edgewise crush resistance

(non-waxed edge method)";

— specifications for the compression testing machine have been replaced by reference to ISO 13820;

— introduction has been updated further highlighting the impact of edge effects and the incomparability

of different test methods;

— scope has been complemented by additional information about the corrugated fibreboard grades;

— terms "buckling" (3.2) and "tipping" (3.3) were included into Clause 3;
— Clause 6 "Sampling" has been revised;
— Clause 9 "Procedure" has been updated and a constant feed rate has been added;
— Clause 11 "Test report" has been updated;
— Annex A has been revised;
— Bibliography has been updated;
— editorial changes and adoption to ISO regulations.

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 four groups as follows:

a) Those in which a carefully cut rectangular test piece is tested without any special treatment or

modification (e.g. this document).

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).

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 (e.g. JIS Z 0403-2).

d) Those in which carefully cut rectangular pieces are tested with edges clamped to prevent the result

from being influenced by edges effects (e.g. TAPPI T 839).

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 and experience has shown that results for the

four groups of test methods will not correlate, but it can be shown that most of them can be used (at

varying levels of accuracy) to predict the top-to-bottom compression strength which will be achieved

when the board is properly converted into a transport package, provided that the formula to predict

BCT values from ECT results is based on data from the ECT method being used.

This document 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), c) and d). This systematic difference is due to edge effects.

Other methods can 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.

Corrugated fibreboard — Determination of edgewise crush
resistance (non-waxed edge method)
1 Scope

This document specifies a non-waxed edge method for the determination of the edgewise crush

resistance of corrugated fibreboard.

It is applicable to all corrugated fibreboard grades from K to D, including manufacturers specification

grades of the similar dimensions. For E grades it is applicable if no buckling and/or tipping occurs

during measurement. Under the defined test piece dimensions, grades finer than E are excluded, since

they are not measurable due to buckling and tipping.

constitutes requirements 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.

3 Terms and definitions
For the purposes of this document, the following terms and definitions apply.

ISO and IEC maintain terminology databases for use in standardization at the following addresses:

— ISO Online browsing platform: available at https:// www .iso .org/ obp
— IEC Electropedia: available at https:// www .electropedia .org/
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 with the flute structure perpendicular to the loading

surfaces
3.2
buckling

failure mode distinct from pure compression, where the mid-part of the sample moves substantially out

of the vertical plane creating a “c” or similar shape

Note 1 to entry: This can occur when the bending resistance of the sample is lower than the compression

resistance of the sample for the given geometry of the test piece, or when sample edge imperfections add an

angular or rotational component to the force from the loading platens.
