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).
Any trade name used in this document is information given for the convenience of users and does not
constitute an endorsement.
For an explanation on the meaning of ISO specific terms and expressions related to conformity assessment,
as well as information about ISO’s adherence to the World Trade Organization (WTO) principles in the
Technical Barriers to Trade (TBT) see the following URL: www.iso.org/iso/foreword.html.
This document was prepared by the European Committee Standardization (CEN) Technical Committee
CEN/TC 172, Pulp, paper and board, in collaboration with ISO Technical Committee 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 second edition cancels and replaces the first edition (ISO 12625-4:2005), which has been
technically revised with the following changes:
a) “stretch at break” was replaced by “stretch at maximum force”;
b) in Clause 7, a more detailed description of the preparation of the test pieces was included;
c) the number of test pieces required has been clarified with more detailed information;
d) in Clause 8, the procedure for the measurement was clarified;
e) in Clause 10, additional information is to be included in the test report;
f) this document has been editorially updated.
A list of all parts in the ISO 12625 series can be found on the ISO website.

INTERNATIONAL STANDARD ISO 12625-4:2016(E)
Tissue paper and tissue products —
Part 4:
Determination of tensile strength, stretch at maximum
force and tensile energy absorption
1 Scope
This document specifies a test method for the determination of the tensile strength, stretch at
maximum force 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.
[6]
In cases where impurities and contraries have to be determined, ISO 15755 applies for these
detections in tissue paper and tissue products.
2 Normative references

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.
