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 3039 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 second edition cancels and replaces the first edition (ISO 3039:1975), which has been technically revised
to include precision data.

Introduction
This International Standard describes a procedure where the separated component layers are allowed to dry
freely, i.e. unrestrained. In 2008, an international round-robin was performed to compare precision data
between the two drying procedures: free drying (which can involve shrinkage) and restraint drying (where the
layers are prevented from shrinking). As no statistical provable difference in the repeatability and the
reproducibility between the two drying procedures was observed, the faster and simpler procedure, i.e. the
free drying method, was chosen for this International Standard. Precision data for free drying are given in
Annex A.
There is an indication from test results that some of the adhesive enters and stays in the papers it comes in
contact with, and is not or cannot be removed by the method we use. Thus, the results for layers will generally
be greater than the initial values.

INTERNATIONAL STANDARD ISO 3039:2010(E)

Corrugated fibreboard — Determination of grammage of the
component papers after separation
1 Scope
This International Standard specifies a method for determining the grammage of the component layers from
which corrugated fibreboard has been made.
This International Standard is applicable to all types of corrugated fibreboard.
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, board and pulps — Standard atmosphere for conditioning and testing and procedure for
monitoring the atmosphere and conditioning of samples
3 Terms and definitions
For the purposes of this document, the following terms and definitions apply.
3.1
grammage
mass per unit area
mass of a unit area of paper or board determined by a specific method of test
NOTE Grammage is expressed in grams per square metre.
[1]
[ISO 536:1995 , definition 3.1]
3.2
corrugated fibreboard
board consisting of one or more sheets of fluted paper glued to a flat sheet of board or between several
sheets
[2]
[ISO 4046-4:2002 , definition 4.49]
3.3
layer
component that is a part of corrugated fibreboard, which normally comprises a fluted layer (fluting) and a flat
layer (liner) on each side

3.4
facing
linerboard (liner) used as the flat component of corrugated fibreboard
[ISO 4046-4:2002, definition 4.66]
3.5
fluting medium
corrugating medium
fluting paper or board intended for use in the manufacture of corrugated fibreboard
[ISO 4046-4:2002, definition 4.73]
3.6
linerboard
board used as the facing material in the production of combined corrugated fibreboard, solid fibreboard or
“carton compact”
[ISO 4046-4:2002, definition 4.105]
4 Principle
Separation of the components of corrugated board specimens, to determine their grammage, by soaking in
water so that the component layers can be separated. Drying and conditioning of the component layers.
Determination of grammage of the individual layers.
5 Reagents
5.1 Tap water, normally having a temperature of 20 °C to 30 °C but not exceeding 60 °C.
6 Apparatus
Use ordinary laboratory apparatus and the following.
6.1 Tank, of sufficient size for immersion of the test specimen, to contain water at room temperature (20 °C
to 30 °C) or hot water not exceeding 60 °C.
6.2 Cutting device, for cutting circular (diameter 112,8 mm ± 0,5 mm) or square (length 100 mm ± 0,5 mm)
specimens from the corrugated fibreboard.
6.3 Drying oven, capable of maintaining the air temperature at 105 °C ± 2 °C, and suitably ventilated.
6.4 Balance, with an actual scale interval of 0,001 g which makes
