ISO 12625-4:2005(E)
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 12625-4 was prepared by the European Committee for Standardization (CEN) Technical Committee
CEN/TC 172, Pulp, paper and board, in collaboration with Technical Committee ISO/TC 6, Paper, board and
pulps, Subcommittee SC 2, Test methods and quality specifications for paper and board, in accordance with
the Agreement on technical cooperation between ISO and CEN (Vienna Agreement).
This first edition cancels and replaces EN 12625-4:1999, which has been technically revised.
With regard to EN 12625-4:1999, the following changes have been made:
a) a more precise definition of the measurement was added;
b) “preparation of test pieces” was explained more exactly;
c) editorial updating.
ISO 12625 consists of the following parts, under the general title Tissue paper and tissue products:
 Part 1: General guidance on terms
 Part 3: Determination of thickness, bulking thickness and apparent bulk density
 Part 4: Determination of tensile strength, stretch at break and tensile energy absorption
 Part 5: Determination of wet tensile strength
 Part 6: Determination of grammage
 Part 7: Determination of optical properties

Tissue paper and tissue products —
Part 4:
Determination of tensile strength, stretch at break and tensile
energy absorption
1 Scope
This part of ISO 12625 specifies a test method for the determination of the tensile strength, stretch at break
and tensile energy absorption of tissue paper and tissue products. It uses a tensile-testing apparatus
operating with a constant rate of elongation.
It also specifies the method of calculating the tensile index and the tensile energy absorption index.
It is expressly stated that the detection of impurities and contraries in tissue paper and tissue products should
be applied according to ISO 15755.
For the determination of moisture content in tissue paper and tissue products, ISO 287 should be applied.

3 Terms and definitions
For the purposes of this document, the terms and definitions given in ISO 12625-1 and the following apply.
3.1
tensile strength
maximum tensile force per unit width that a test piece will withstand before breaking in a tensile test
3.2
tensile index
tensile strength divided by grammage
3.3
stretch at break
ratio of the elongation of a test piece, over its initial length, at the moment when the maximum tensile force is
reached during a tensile test
NOTE Stretch at break is expressed as a percentage of the initial length.
3.4
tensile energy absorption
amount of energy absorbed per unit surface area of a test piece while being stretched, until the onset of break
(the moment of maximum tensile force) in a tensile test
3.5
tensile energy absorption index
tensile energy absorption divided by grammage
[ISO 1924-2:1994]
4 Principle
A test piece of tissue paper or a tissue product, of given dimensions, is stretched to break at a constant rate of
elongation using a tensile-testing apparatus that measures and records the tensile force as a function of the
elongation of the test piece.
From the recorded data, the tensile strength, the corresponding stretch at break, and the tensile energy
absorption are calculated.
5 Apparatus
5.1 Tensile-testing apparatus
The tensile-testing apparatus shall be in accordance with ISO 1924-2. It is capable of stretching a test piece of
tissue paper or tissue product of given dimensions, at a constant rate of elongation of (50 ± 2) mm/min, and
recording the tensile force as a function of elo
