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

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

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

Note 1 to entry: The term "coating" has a different meaning in the tissue industry from that in the printing and

writing paper manufacturing industry. In the paper industry, the term "coating" refers to

---------------------- Page: 17 ----------------------
SIST EN ISO 12625-1:2019
ISO 12625-1:2019(E)
3.18.6
wet creped paper

creped paper (3.18.1) typically produced on a wet creped tissue machine, where creping takes place
