ISO/FDIS 9073-1

Nonwovens — Test methods — Part 1: Determination of mass per unit area

Measurement of the area and mass of a test piece and calculation of its mass per unit area in grams per square metre. In order to meet the specific needs of nonwovens, alternative requirements to those listed in ISO 3801 are specified in this part of ISO 9073. These are: a) a different sampling procedure; b) an alternative specification for dimensions of test piece; c) a greater accuracy for the balance.

Nontissés — Méthodes d’essai — Partie 1: Détermination de la masse surfacique

La présente partie de l'ISO 9073 prescrit une méthode pour la détermination de la masse surfacique des nontissés.

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/directiveswww.iso.org/directives).

Attention is drawn to the possibility that some of the elements of this document can 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/patentswww.iso.org/patents).

Any trade name used in this document is information given for the convenience of users and does not

constitute an endorsement.

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

This document was prepared by Technical Committee ISO/TC 38, Textiles, in collaboration with the

European Committee for Standardization (CEN) Technical Committee CEN/TC 248, Textiles and textile

products, in accordance with the Agreement on technical cooperation between ISO and CEN (Vienna

Agreement).

This second edition cancels and replaces the first edition (ISO 9073-1:1989), which has been technically

revised.
The main changes compared to the previous edition are as follows:
— the title has been changed;

— the title has been changed from "Textiles — Test methods for nonwovens — Part 1: Determination of

mass per unit area" to "Nonwovens — Test methods — Part 1: Determination of mass per unit area";

— the mandatory Terms and definitions clause (Clause 3) has been added and subsequent clauses have

been renumbered;
— the text has been reviewed and improved;
— Addition of principle.
— Clause 4, "Principle", has been added.
