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

Introduction
This document defines terms for the determination of the physical properties of tissue paper
manufactured using creping or un-creped techniques, and includes products made using a combination
of these tissue-making processes.
Tissue products form an important and growing market for single-use disposable hygiene and
industrial products. The current range of these familiar products includes toilet tissue, facial tissue,
kitchen/household towels, hand towels, handkerchiefs, table napkins, mats, industrial wipes, other
absorbent tissue papers and lotion-treated products.
Tissue-paper-manufacturing technology has evolved and diverged from "ordinary" paper technology
so that a new glossary has become necessary.
The purpose of this document is to allow a common understanding of the various tissue-making
terms between tissue manufacturers, tissue converters and tissue customers, and to facilitate the
harmonization of testing methods. Each listed term is briefly defined and, where this was thought to
be useful, an example is given. While elaborating this document, English was chosen as the original
language. It was then stated that some expressions cannot be translated into another language. For
those cases, the English expression is used.

supported by a felt, and entirely dried by the Yankee cylinder
3.15.1
Yankee coating
coating package
combination of adhesive/release agent and potentially other chemical additives applied to the Yankee
cylinder (3.63) prior to the creping operation in order to ensure a homogeneous and even contact
between the tissue paper (3.58) web and the drying cylinder, and induce an easy release of the web
from the creping blade
3.15.1.1
adhesive
component of Yankee coating (3.15.1) delivering specific adhesion, durability and hardness
characteristics
3.15.1.2

SIST EN ISO 12625-1:2019
ISO 12625-1:2019(E)
3.18.6
wet creped paper
