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.

assessment, as well as information about ISO’s adherence to the WTO principles in the Technical Barriers

with the Agreement on technical cooperation between ISO and CEN (Vienna Agreement).

This second. edition cancels and replaces the first edition (ISO 12625-3:2005), which has been technically

revised.
With regard to ISO 12625-3:2005, the following minor changes have been made:
a) title changed; “bulk” added;

b) the accuracy data in Annex A were adjusted to the existing equipment capabilities and calibration

procedures;,

c) preparation of test pieces more precisely described, 7.1 and 7.4 reformulated;

d) editorial updating.

ISO 12625 consists of the following parts, under the general title Tissue paper and tissue products

— Part 1: General guidance on terms;

Introduction
Thickness is an important property of tissue paper and tissue products.

In the tissue industry, thickness-related parameters, such as the roll diameter of rolled products

(kitchen towel) or the stack height of folded products (paper towels) are often measured. However, the

fact that not only end-use tissue products, but also the base tissue paper from which these products are

made, is the subject of trade between companies and countries, means that there is a genuine need for a

consistent measure of thickness that can be applied to tissue products at any stage of their manufacture.

The thickness of tissue paper and tissue products is known to be dependent on the pressure applied to

the material at the time of measurement. Several different loading pressures, pressure-foot diameters

and loading speeds have been used within the tissue industry. This part of ISO 12625 has been prepared

by harmonizing those standards applicable to tissue and tissue products currently in use. It specifies a

single loading pressure, foot diameter and loading speed to be used for all thickness measurements of

tissue and tissue products.

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 or ISO 638 should

be applied.

1 Scope

This part of ISO 12625 specifies a test method for the determination of thickness and bulking thickness

and the calculation of apparent bulk density and bulk of tissue papers and tissue products under a

pressure of 2,0 kPa.

NOTE This part of ISO 12625 has been developed to provide a consistent test method for the determination

of thickness and density of tissue paper and tissue products. Corresponding test methods for paper and board in

general are covered in ISO 534.
